TSP is short for trisodium phosphate. Painters often use this for preparing surfaces prior to painting. However, this alkaline cleaning agent can also be used for wall or floor tiles that need extra heavy-duty cleaning, such as tiles hazy with soot or with grout dust. Because TSP is a strong chemical, you will need to avoid skin and eye contact with this product.
