Tub and Shower Soap Scum Buster! BEST tub and shower cleaner I've ever used! I kept seeing pins just like this one and had to try it one day I was out of bathroom cleaner. I didn't have dawn so used the Kirkland brand ecofriendly stuff i had and it worked. The stuff sticks to the shower walls, consistsncy is great. It foams or suds up a lot so a little goes a long way. Never buying product again.
