Hi Judy - This is the shower cleaner that we use to help keep grout and tiles clean and minimize the mildew - it works on kitchen grout too. I've also included a great article about mold if it's gone that far. Hope this helps! Hugs, Holly

If it's normal dirt, you can clean with a cup of hydrogen peroxide to 2 gallons warm water. If it's really bad build up, Lysol Lime & Rust Remover Toilet Bowl cleaner, comes in a black squirt bottle. Scrub with Scrub Daddy or Mr. Clean Magic Eraser. If stubborn, use a scouring stick to scrub.
