The joints are cleaned with cleansing materials that we find in stores with sanitary equipment and tiles. There are special acid cleansers for difficult stains (e.g. Bio Clean B 21) that clean, shine and revive the colors of the putty joint.

BE EXTREMELY CAREFUL WITH THE ACID CLEANSERS. THEY ARE NOT APPROPRIATE FOR USING ON MARBLES, POROUS TILES, LIMESTONE STONES, DECORATIVE STONES AND SILK SCREENED TILES.

ALWAYS READ THE INSTRUCTIONS FIRST.

On the surfaces where we cannot use acid materials, we apply cleansers of a milder form, e.g. the Clean B 22.
