Hi Amanda - 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. Hope this helps! Hugs, Holly

make paste from Dawn dish soap and baking soda smear on tile/tub use new stiff toilet bowl brush to scrub it all over let sit about 10 minutes then spritz with vinegar lots of fizzing and rescrub it well let solution sit on tiles again then rinse with hottest water possible. don't be shy with the products and leave drain stopper/plug in closed so it doesn't all run down the drain while you are cleaning.
Folex for grout. You won’t be sorry. Also, I bought the scrubbers to put in the electric drill/screwdriver and love them!
Your basic (professional grade is what I use, I'm not sure if it's stronger, but I get the giant one with the pump spout from Lowe's or Sam's) Blue Dawn dish soap is miraculous in bathrooms. I'd use it with a brush or scruffie thing and see what happens. Once I learned about using it to clean tubs, I've never used anything else! It totally makes tub scrubbing a breeze!
