Vinegar is acidic and can etch certain natural stone, such as marble, travertine and limestone. The occasional use of vinegar on porcelain or ceramic tile with cement-based grout should not cause damage. However, frequent or regular use can discolor and weaken grout and should not be used for routine maintenance. There are several professional-grade UltraCare acidic cleaners that are available when needed, including UltraCare Sulfamic Acid Crystals, UltraCare Cement Grout Haze Remover and UltraCare Acidic Tile & Grout Cleaner.
A thin layer of residue, or grout haze, left on the tile surface can usually be removed with a dry cloth. If it is more stubborn to remove, use the appropriate UltraCare product recommended in our technical document: “Removing Grout Haze.”
