I discovered a non-toxic, do-it-yourself cleanser that I just love. I clean my bathroom grout and my bathtub with this mixture, and it gets all the Soap scum off my tub which the toxic cleansers failed to do. Believe me, I tried enough times. This has also worked on my stovetop and I used it to clean my sinks as well. Take about 2 Tbs. of Baking Soda and add some liquid soap to form a paste. It kind of looks like Soft Scrub. I used my Soft Soap hand soap, but dish soap would work as well. I just used a bowl to make this in. Add it to your surface you want to clean with a rag, sponge, or brush. I let it sit for 15 minutes, then washed it off with hot water. My grout was whiter as it had bluish color to it from the water no doubt. I have issues with soap scum and we use alot of bubble bath and bath oils so it leaves this ick, so this eliminates that entirely. I love this stuff!
