Open the CIPO recordAbstract From the Canadian patent
Acidic floor cleaning compositions are employed to improve the coefficient of static friction of floors especially quarry tile, in environments conducive to the buildup of slippery-when-wet films, e.g. fast food restaurants. Such compositions, preferably buffered and containing surfactants, also improve the appearance of the floor by maintaining the floor free of ugly film without any significant attack on the grout or the tile.
