Question

How do I clean mosaic tiles? Many people insist on using hydrochloric acid. Is this chemical right for cleaning mosaic tiles? If not, what would make them more white and shiny?


Answer

It depends on the type of mosaic tile. If marble, or other calcium-based stone, acid would be very harmful. If ceramic or other clay-based tile, try an alkaline solution, followed by agitation and rinse. If tile or grout is not completely clean, try a safer acid solution. Look for a product that is an organic salt, with an acidic pH. These are less harmful to the technician using the product. Rinse after use and then place an alkaline solution over all areas where acidic solution was applied to prevent long term degradation of the grout. Rinse thoroughly and dry.
