“Terrific product because it has throughly cleaned the backsplash from "bacteria and mildew" gathered over time on an untreated kitchen backsplash. Only used on a small section with great results. Project will begin in late Fall before the Holidays!”
“Residential use bathroom tile - bought a small kit 2018? And it worked great - took off years of white hard water film and brought shine back to tiles only used pre treat in kit and it was enough - been five years so just did a light clean with the pre treat this time...happy with product ....how often can I use pre treat safely..do not want to overdo chemicals-thanks”
