Natural stone is exposed to pollution because of its high porosity and unfavourable influences of the environment. Inside of premise, the stone is frayed, and is exposed to everyday pollution. Therefore, natural stone requires proper care and it is protection and cleaning of the stone.
There are several kinds of cleaning the stone, it is chemical, mechanical and physical-chemical cleaning.
For chemical cleaning of stone uses special cleaners that can remove dirt, stains from paint, rust, also the remnants of glue or cement. For acid category of quartzite, sandstone, granite and other are used acid cleaners. Neutral cleaners are used for limestone, marble, slate and similar stones.
Next type cleaning of stone is mechanical. It is includes scraping, removal of dust, sandblasting and etc.
Physico-chemical cleaning of stone is the combination of chemical and mechanical cleaning.
For her are uses steam under high pressure washing with water or with chemical methods.
The frequency and degree of protection is determined based on the physical properties of rock and mineral composition. In order to correctly identify the mode of cleaning is enough to just look at the stone surface and it will become clear when and what the procedures for cleaning should be performed.
Products of natural stone faster and easier submit to the influence of temperature on outdoor air, precipitation, and toxic waste. In this connection, a terrace and pool area should be cleaned with warm water using special detergents. Perhaps the use of soft bleach to remove mold, moss and chronic pollution.
For remove soap scum in the bathroom , usually on the surface of natural stone should be used that do not contain acids or weak solution of ammonia and water. It is necessary to remember that with frequent use of ammonia surface of the stone can become darker.
In whole, for domestic everyday can use universal polymeric liquids, which simultaneously serve and protect, and car polish . They do not change the natural colour of the stone, do not leaving marks, not form a pellicle.
If heavily dirty spot of stone (traces of dirt, oil, paint, lime pellicle) is recommended to use alkaline cleaners. They have a very strong degreasing effect and open the pores of the stone for further processing by protective means.
To improve the appearance of natural stone and to protect it during operation, apply the wax of protective equipment. They are also intended to restore the faded colors of the worn surfaces of natural stone cladding for protection from penetrating into the micro-organisms.
If these means are not able to solve the problem of pollution (rust, cement incrustations, mineral deposits) should apply the most powerful tools - acidic cleaners. But it should be remembered that such means "eat" polishing.
It is not recommended to use too much cleaning agents, dry paste and creams, powdered detergent. You should not use cleaning agents that contain lemon, vinegar or other acids.
