ALCALAGRES porcelain stoneware in natural finish is a product that has virtually no micro-porosity and is constant over time, unlike other materials used in paving (natural stones, marble, granite, wood, glazed and unglazed ceramics, etc.) which have porosities and cracks on their surface that become more pronounced with use.

Porcelain stoneware has a beauty that might be masked once its installation is finished. The small cement build-ups that have been generated when installing it, if not removed in time, can seriously affect the final result, so once the grouting process is finished and having left a prudential waiting time for the bonding and grouting material to have dried properly, a first cleaning must be carried out.

The resistance to chemical attack of porcelain stoneware allows cleaning with concentrated detergents. Check that no product used contains hydrofluoric acid, as it damages porcelain stoneware and any other material of ceramic origin. The products tested and recommended by ALCALAGRES for the first cleaning are the KERANET cleaner from MAPEI or a cement residue remover - ammonia water (salfumant or similar) reduced to 50 - 60% in water. In either case it is advisable to test one of the unused pieces to make sure it does not damage the material.

ALCALAGRES porcelain stoneware in natural finish requires no special maintenance. For daily cleaning, the use of hot water with a neutral detergent is recommended.  For rustic and non-slip finishes it is advisable to use a hard fiber brush to remove dirt from the rough surface.

For large surfaces the use of industrial scrubbing machines with hot water is recommended.

Never use waxes or oily or colored soaps and follow the instructions of the machine manufacturer regarding the use of detergents.

However, the maintenance of polished porcelain stoneware requires greater attention, especially with plain and light colors. This material is supplied with a surface protector that allows easy cleaning immediately after installation.  This protective layer must be removed with the first cleaning at the end of the job.

Daily cleaning can be done with a slightly wet mop so that the typical shine of the polished surface is perfectly restored.

If any liquid is spilled on the floor, it is recommended to act diligently.

In areas such as workshops, bars, industrial kitchens, etc., a special surface protector for porcelain stoneware can also be used, which prevents stains from adhering strongly to the surface and makes subsequent cleaning easier. However, there are specific products on the market to clean all types of stains: rubber, grease, paint, marker, etc. It is important to know the origin of the stain in order to use the right solvent.

The use of products with acid components does not attack ALCALAGRES Porcelain Stoneware (except hydrofluoric acid) but their use may affect the safety of people and other decorative or constructive elements, so they should be used with caution and always following the indications of the manufacturer of the chemical product.

It has been proven that caustic soda concentrated and deposited for some time on porcelain stoneware alters the polished appearance of this material, but does not affect its technical features. ALCALAGRES is not responsible for any damage that these products may cause to materials other than porcelain stoneware.

Decorative accessories containing metal or glass effects must be treated with care both in their installation and maintenance. These materials do not have the same strength qualities as porcelain stoneware. The use of physical or liquid abrasive products can damage these parts. Be especially careful when applying the grout, wipe immediately with a soft, very damp cloth or sponge. If defects are found in these parts, do not install them.

It is advisable to install industrial doormats at the entrances of public premises, especially if the access is direct from the street. This precaution will prevent slippage by "aquaplanning" and will achieve greater durability of polished surfaces.

Below is an indicative table with the most frequent stains and how to treat them with the usual chemical products on the market.
