"I have found a new product that works on the grout, the caulking and the floor of my shower, which is Swanstone and white. Plus, it works fast. It is a product from Clorox called Clorox Precision Pour Bleach Gel. I have only seen it in one grocery store in my area, but it is great. No scrubbing; just let it sit for a few minutes. It also works on the walls because it doesn't run off like regular bleach. I found it when I was searching for a bleach pen, which did well on wall grout. I am assuming this is a replacement for that."
Thank you for the new information on the Clorox Precision Pour Bleach Gel. I also am happy to hear that the toilet paper trick works well to remove mildew from the surface of affected caulking.
