Procedures for tile care and maintenance
There are three phases in the process of cleaning and maintaining tiled surfaces. General cleaning and problem solving are addressed below…
Phase One
During tiling and prior to handover
Phase Two
General cleaning of tile surfaces
Phase Three
Problem Solving
During tiling and prior to handover
We begin by stressing the importance of protecting tiled surfaces during the laying process and immediately prior to the area being used.
The tile layers are responsible for sweeping the floor prior to commencement and during the installation process, thus removing any grit or debris which may scratch or mark the surface of the tiles.
Regardless of the area you have tiled or the type of tile used, all products require adequate protection during the installation process and prior to handover.
During construction a floor is laid in sections, then grouted. Surplus grout is washed off taking care to avoid the joints. After the grout has cured, a further rinse is necessary before the floor is then protected by a cover of taped soft board or an equivalent. This should be left in place until all other trades have completed their work and the floor is no longer at risk from building damage.
The condition of a cleaned tile floor is dependant on using the appropriate machinery, cleaning solutions and methods. The machinery and manpower required to achieve the best possible cleaning result is the responsibility of the cleaning and maintenance contractors. Your cleaning contractors should ensure a new floor has undergone a Builders Clean and is in a good condition prior to the hand over from the builders to avoid inheriting long term cleaning problems.
Builders Clean
An initial Builders Clean is fundamental to the maintenance of a newly laid tile floor. Failure to execute this procedure correctly will cause problems particularly where anti-slip tiles are concerned. The grouting process leaves an invisible film of cement residue which, if not completely removed, will allow the build up of dirt and grime reducing the floor’s slip resistance.
Non-slip surfaces
Due to their particular non-slip, rough or structured textures, non-slip surfaces are more difficult to clean. Therefore pay particular attention to cleaning methods, in particular clean sooner and use motorised brushes with white and beige discs.
The Builders Clean should be carried out as follows:
The floor must be swept and vacuumed and all dust and debris removed.
Using a single disc professional cleaner with green pads for plain surface tiles and brush pads for anti-slip tiles together with a phosphoric based acid detergent such as Lithofin KF range of products normally diluted 1:5 with water (this can vary according to the degree of builders/cement residue). This will remove existing build ups of grout residue, lime scale, rust stains, scum film, uric acid salts and shod foot dirt. The procedure should be carried out in areas of approximately 50m2 at a time, the solution is placed on the said area and must be left for three to five minutes to allow the chemical to work - but not allowed to dry. The scrubber/drier using green pads or brush pads should be used to work the floor in one direction continuously and then in the other direction, for approximately 15 minutes, ensuring that the floor is not allowed to dry. The dilution of the detergent and water is dependent on the degree of cleaning required.
Use a vacuum wet pick up to remove the soiled water.
Rinse the floor twice, using clean warm water.
Vacuum up the soiled water, ensuring that all traces of the acid have been removed.
The machine and its pads should be cleaned thoroughly after each use. The rinsing is an integral part of the cleaning process, as any chemicals left on the tiles will harden and attract dirt.
Protecting after installation and before handover
In many instances other tradespersons will have to walk on the finished tiling to work in the area in question or adjacent locations.
Once the adhesive has set, and tiles can be subjected to foot traffic, the builder should ensure that the surface is protected by covering the tiles with an appropriate protective layer – cardboard, plywood, building paper, felt or a proprietary product designed specifically for this purpose. Critically, the floor should be swept and be completely cleaned before the protective layer is applied, and any objects that may scratch the tiles surface should be removed.
In addition, other trades should be advised not to place tools, or tool boxes directly on the surface of the tiles. Care must be taken to avoid spills of plaster or paint. Loose sand and cement particles can scratch or mark tiles. Blue metal aggregate can scratch the hardest ceramic surfaces, when trapped in the soles of work boots.
Care should be taken to avoid dropping heavy objects, or dragging ladders and other equipment over the surface of the tiled floor.
Critically the tiled floor should be examined when work is completed, just prior to handover.
General cleaning of tile surfaces
Ceramic floor and wall tiles generally require minimal levels of care and maintenance. Nevertheless, it is important to understand how a particular tile surface should be cleaned and maintained. For example, the maintenance of regular glazed tiles, is different to the processes required to clean and maintain unglazed materials. Fortunately those processes are relatively simple to understand and apply.
Glazed Floor Tiles
Traditional glazed ceramic tiles and glazed porcelain floor tiles laid in residential homes require minimal maintenance.
Tiles laid in commercial environments or public spaces will require daily cleaning and maintenance.
In a residential environment the levels of cleaning and general maintenance are determined by the location of the floor tiles and the volume of foot traffic and general wear and tear the surface is subjected too.
In a busy home with multiple occupants, including children and pets daily maintenance may be required. In an apartment where grit and dirt are rarely transported to the apartment’s interior, or in a home occupied by minimal occupants, maintenance can be carried out on a weekly basis.
Regardless of circumstances the cleaning and maintenance processes required to clean and maintain glazed ceramic tiles or glazed porcelain tiles are identical, only the frequency will vary, in response to the number of occupants and the general levels of foot traffic.
Tiles are best kept clean by adopting the following simple steps and procedures:
In circumstances where ceramic surfaces may be subjected to dirt or grit, brought in from the street or the garden, ensure that an appropriate entry mat is provided, or change footwear.
Immediately wipe-up spills of any liquid that may create a slip hazard or dry and prove difficult to remove.
Sweep floors with a soft broom.
Vacuum when necessary.
Wash floors with a solution of warm water and a soapless pH neutral cleaner.
Frequently a combination of light sweeping and cleaning with a microfiber wipe is all that is required.
If there is a build-up of grease the occasional use of a detergent which incorporates an organic solvent or a highly-alkaline detergent (pH9) will resolve the issue. Note that overuse of acidic cleaning materials may attack the grout or produce a haze on the surface of the tiles.
Textured Glazed and Unglazed Floor Tiles
There are a variety of unglazed ceramic surfaces which include:
Natural (matt)
porcelain Terracotta
Quarry tiles
Natural (matt) finished porcelain tiles are generally impervious, which means that their surface is highly resistant to liquid spills and subsequent staining or a build-up of grime or dirt. However, in certain circumstances these surfaces are sealed to add a layer of protection which makes it easier to remove residual material.
Most terracotta tiles are relatively porous, so they are sealed to prevent spills of liquid being absorbed into the body of the tile.
Quarry tiles are generally impervious, but may be sealed to permit easy cleaning and removal of residual grime.
The general cleaning processes used to clean and maintain unglazed surfaces are:
Use a pH neutral soapless cleanser. Avoid using detergents which are excessively acidic or alkaline, as they can cause irreversible damage to unglazed ceramic surfaces. In particular, avoid use of cleaners which contain wax, sodium silicate, or other additives which create a sticky residue that attracts dirt.
Sweep, dust-mop or vacuum the surface.
Dilute the chosen cleanser in warm water and apply using a mop and bucket. Large spaces may be cleaned using a mechanical scrubbing machine. Allow the cleansing solution to remain on the floor for sufficient time to penetrate and soften dirt or accumulated grime. Do not allow the solution to dry. Agitate, the surface mechanically or with an appropriate scourer or brush to disperse contaminating material, prior to completely removing the cleaning solution, using clean water. When using hand held or mechanical scourers, it is advisable to use ‘white’ pads to avoid scratching.
Rinsing dirt water should be replaced frequently.
Remember, the final application of clean water actually removes the dirt.
Remove any excess water with a wet-vac or mechanical scrubbing machine that has a suction function.
Wet Areas
In wet areas like showers and around swimming pools a build-up of various contaminants like body fat, oils, soap residue and liquid spills may occur. In humid conditions organic growth, algae and mould may appear. These potential contaminants can be removed with an appropriate, heavy-duty (problem solving) cleaner.
Slip-Resistant Tile Surfaces
Textured or profiled slip-resistant tile surfaces may attract various fibres, organic dirt and liquid substances which create a gradual build-up of grime. These surfaces will require regular maintenance, including the use of a rubber stubble or micro-fibre broom, to agitate and remove potential contaminants.
Large Areas
Clean large floor areas with a rotary or cylindrical scrubbing machine.
If the machine features a ‘suction drying’ function, ensure it is switched off. • This will allow the water/cleaning solution to penetrate and dissolve layers of dirt and grime.
Wait 15 minutes before repeating the scrubbing process, using water only. • Rinse the floor thoroughly.
The final rinse should remove all residue particles of dirt/grime.
In some instances use of a high power water-jet will be sufficient to remove loose particles of dirt. This will not damage the tiles, but it may erode cementitious grouts if the process is conducted regularly.
Polished Porcelain
Many leading European and Asian manufacturers produce polished porcelain tile. In layman’s terms, the manufacturer obtains a bright, highly polished, marble-like surface by grinding down and then polishing the hard surface of natural, unglazed porcelain.
In some instances, the polishing process may open micro-pores in the surface of the tile, which attract a build-up of grease or grime, or permit spills of liquid contaminants to seep into the surface of the tile creating a stain which may be difficult to remove.
Note: It is worth repeating that any spills should be wiped up as quickly as possible.
Sealing Polished Porcelain Tiles
Many manufacturers state that their polished porcelain tiles comply with International Standards Organisation (ISO) 13006 – 2013; 4.3.2-2(i), which classifies products that have a water absorption rate that does not exceed 0.5 per cent – Class B1a. In theory these products should not require sealing.
Unfortunately, some porcelain tiles although still within the required standard limits, have slightly higher rates of porosity which may result in a build-up of grime, dirt, discolouration and in some instances staining caused by liquid penetration.
If in doubt, you can conduct a simple test by using an eye-dropper to deposit small amounts of potential contaminants on the surface of a tile. Deposit small samples of red wine, ink, cooking oil and lemon juice on a tile’s surface, leave the substances on the floor for 15 to 20 minutes and then try to wipe the residue away. If any of them have seeped into the surface or leave a visible stain, the polished porcelain requires sealing.
The sealing process is relatively simple, some tile layers will carry out the task, or a sealing specialist can be consulted.
Maintenance
In general terms, the maintenance of polished porcelain is similar to the processes used to clean and maintain regular glazed ceramic tiles and glazed porcelain. Sweep the surfaces regularly, mop carefully with a minimal amount of water, and vacuum or use micro-fibre wipes as required.
By sealing polished porcelain tile it is easier to clean and maintain the surface. The manufacturer of the sealing product will also supply products which can be used to carry out general maintenance of the sealed surface.
A choice will be made between topical sealers which sit on the surface and penetrating sealers. The latter type is usually preferred with polished porcelain.
Refer to the following chapter on Problem Solving for further advice.
Glazed Wall Tiles
Kitchen wall tiles can be splashed during food preparation and cooking processes, however these marks will not pose a problem, especially if they are promptly wiped away.
Bathroom wall tiles particularly in the shower where soap and shampoo residues will eventually develop a feint film which will detract from the overall appearance.
In some instances, the water supply may contain calcium carbonate or calcium sulphate, which can create a white stain.
A light wipe with a soft cloth will remove soap, shampoo and calcium before it dries.
If a problem develops it can be easily resolved by using warm water with a pH neutral cleaner, which will provide a clean, shining surface.
Harsh and abrasive cleaners should be avoided at all costs, especially on decorated feature tiles as some feature tiles contain a metallic finish that can be easily scratched
Problem solving
In spite of the fact that ceramic tile is the simplest surface to clean and maintain, problems can occur. We have seen that tiles require minimal levels of maintenance. In some instances, problems are created by using inappropriate and often unnecessary cleaning and cleansing materials or by allowing stains (staining agents) to set on the tile surface for long periods. Light sweeping, light mopping with clean water and a pH neutral soapless cleanser, if absolutely necessary, will suffice.
In many instances, this task only needs to be completed once a week.
Specialist acidic or alkaline cleaners should only be used to resolve complex staining problems, which rarely occur in private dwellings. Avoid using cleaners which contain wax, sodium silicate, or any additives which may leave a sticky film on the floor that may attract dirt and a subsequent build-up of grime.
Many of the problems outlined below relate to tiles which have a textured or structured surface, these are usually unglazed products.
-
This problem can occur on a variety of tiled surfaces. It is usually created when tile layers hastily complete the grouting process, without washing off residue grout effectively. Some contemporary ceramic products have slightly textured surfaces which can encourage grout to cling to the surface of the tile.
Tile layers should use a clean sponge and clean water to carefully remove excess grout, without dragging grout out of the grout joints. To do this effectively it is important not to commence the wash off process too soon. In addition, residue grout should be completely squeezed out of the sponge, and the water should be changed frequently.
On Warm days grout will dry quicker and will be more prone to adhering to the tile’s surface. In those circumstances, smaller areas should be grouted to avoid sections drying too quickly, leaving behind a feint residue that later proves difficult to remove.
In most instances a light grout bloom will become evident, this can be removed using a dry rag. If grout has not been washed off effectively, this bloom or haze may reappear making the surface look smeared, dirty or dull.
If this problem occurs, the contractor needs to address it promptly, as the longer it is left unattended the harder it becomes to remove the residue grout film, which will attract additional grime.
In some instances, latex contained in grout improvers may be part of the problem, the cementitious element of the grout will have been removed, but feint traces of the latex element of the mix may remain.
At this point, most resort to using general household cleaners which may contain a mild alkaline or mild acidic element, which may not prove successful. Latex is usually removed by using an appropriate solvent to release it from the surface. The floor should be thoroughly cleaned with water prior to application of the solvent.
-
Epoxy grouts are more difficult to remove. These should always be applied and cleaned strictly following manufacturer recommendations. Never leave residues on the tile surface. Most epoxy grout manufacturers have specific dedicated products for the cleaning.
Fortunately, most of our leading manufacturers of adhesive and grout produce problem solving cleaners which will resolve the problem. If grout haze occurs consult with the tile layer to ascertain which grout was used.
Once the floor is cleaned it will no longer be necessary to use these special cleaners on a regular basis.
Always follow the manufacturer’s instructions to the letter. Conduct a test on a small out of the way section of the floor to check that the result is satisfactory.

This may occur in areas which lack adequate ventilation, it may be necessary to install an extractor fan. Mould can be removed by scrubbing with a scourer, using one of the following - bicarbonate of soda, methylated spirits, cloudy ammonia or epsom salts.
-
The popularity of porcelain products encouraged manufacturers to apply a light wax coating to the surface of each tile, to protect the surface of the tile from scratching during the packing, in transit and installation processes.
The majority of these wax coatings are water soluble, they can be removed using a water based alkaline cleanser.
Before removing solvent based waxes let the cleaner dwell on the tile surface for 10 to 15 minutes to dissolve the wax. Your tile retailer can give you guidance.
You should check if your chosen porcelain tile has been coated with wax, your tile layer should be alerted prior to installation.
-
As previously stated, clean water and a mild pH cleanser will be suitable for cleaning the majority of tile surfaces. Use of alkaline or acidic cleaners will often create problems.
Alkaline cleaners should only be used to remove specific stains, they should not form a part of the regular maintenance program.
-
This problem usually occurs in external applications of unglazed ceramic materials and natural stone.
Efflorescence usually appears on the surface of a tile or around the joints in the form of a white powder. This unsightly problem is created by the transmission of liquid salts from below the tiles to the surface. In most new installations the residue can be swept or vacuumed away. The presence of excessive moisture is the prime cause of the problem.
In some instances the problem reoccurs, always remove every trace promptly to prevent hardening and subsequent calcification.
Specialist cleansers are available to treat the problem. These can only be employed when the source of the moisture is identified and if the problem persists a specialist should be consulted.
Guide to Stain Removal for Unglazed Tiles
Unglazed surfaces undoubtedly present the greatest problem in regard to staining, as it is generally harder to remove liquid spills or other marks from textured or rough surfaces. Once again emphasis is placed on early removal. In addition unglazed products are frequently used externally because of their enhanced slip-resistance.
It is probably wise to seal unglazed, matt finished products laid externally around pools and in entertainment areas.
Listed below are some of the remedies which can be used to treat stains on unglazed tiles.
Note: Always read the manufacturer’s instruction carefully and test a small area first to check effectiveness.
| Stain | Cleanser Type |
|---|---|
| Daily Cleaner | PH neutral Cleaner |
| Cooking fats & oils | Solvent based cleaner Acid |
| Ink | Acid based cleaner, Acetone |
| Rust & Oxides | Acid based cleaner |
| Rubber | Solvent based cleaner |
| Ice cream | Solvent based cleaner |
| Paint | Solvent based cleaner |
| Coffee | Alkaline based cleaner |
| Wax | Alkaline based cleanerr |
| Linseed oil | Alkaline based cleaner |
Correct Use
The wrong cleaner is often chosen and in many instances cleaners are used incorrectly so adopt the following procedure:
Select the correct cleaning agent.
Apply the cleaner and allow it to dwell on the surface (The chemicals need time to do their work – usually between 5-10 minutes)
Scrub and agitate the area to be cleaned
Periodically extract the dirt (and cleaning agent) from the surface (by wet or dry vacuum cleaner, squeegee or an absorbent cloth) to determine results. (NOTE: Heavy duty cleaners must be extracted every time they are used).
Rinse the area with clean water. (Any cleaning agent left on the surface can accelerate contamination of the area).
To avoid long term issues immediately wipe-up spills of any liquid which could cause a stain.
Important Notes
Whenever there appears to be a problem, it is generally thought that this can be resolved by using more of the chemical or scrubbing harder with the wrong chemical, which is not effective at all. If the correct chemical and procedure is not used, this only increases the problem and build-up, particularly in instances where general purpose cleaning agents are involved which are a neutral detergent, but not PH7. The products mentioned are all biodegradable and therefore safe for use, as recommended by the manufacturers.
