Pet urine stains tile grout. Cleaning unsealed grout offers more of a challenge than sealed grout, as urine penetrates unsealed grout. To keep the pet from re-staining the same area, pet owners must also remove the urine odor. Basic cleaning products already found in the home will remove pet urine stains from unsealed grout. Sealed grout may need to be stripped, cleaned and sealer reapplied for successful results.
