My home decoration just finished tiles to clean up the tiles when there is a cement with a damp cloth has been wiped out how to do? (My family to buy all the tiles) Will you have nothing to hurt the tile method can be removed? Thank you!
1. Tile cement stains can not be used steel ball, can be used 1500 or 2000 water sand paper gently wipe, or wipe with dilute hydrochloric acid, wipe clean with clean water .2. Clean up the cement residue cleaning agent can try; 3. "Banana water" paint thinner, good decontamination effect, sprinkle a few drops of tiles, wipe and rinse with water
Cement is alkaline, generally removed with acidic substances. Oxalic acid may not be acidic enough. Pour some vinegar up the effect will be better. Industrial hydrochloric acid can also be used after dilution, but to prevent corrosion of the tile itself. To try it a little bit.
If hydrogen peroxide is not used, it is recommended to use stone-specific products, such as strong concentrated cleaning agent, PH value of 10.5 or so. This product can decompose the organic matter on the surface of the stone pollution, and can remove the surface type protective agent. If necessary, the cleaning agent can be mixed with the decontamination powder, which can extend the reaction time of the compound and adsorb the stain to the paste. Before using the compound, first test a small area inconspicuous, such as the corner, and to ensure that the stone surface will not be covered with dark flower marks. Clear the slight scratch operation is relatively simple, the market has a lot of polishing powder for sale. However, the use of polishing powder, most of the need to use a polishing machine or a single rub machine.
If it is glazed tiles, with a gray knife or iron to large scraping off, leaving a small part of the cotton yarn wiped on the line. If it is quintana brick, (that is, no glazed), the first scraping more, and then wipe with a wire wipe off on the line.
