I too love Natures Miracle, but the urine may have soaked into the grout, is this ceramic tile with grout you are referring too? You are going to have to use a lot in the grout area, and maybe even repeat it. The enzymes in the product eat the protein that cause the dog to return to the same spot, but this takes time. You should probably have your grout resealed after a through cleaning because with sealed grout nothing can sink in. Unfortunately sealers wear down, and may need replacing yearly. |
