Cleaned my dirty shower very well. It was mainly mold and soap scum on the grout and tiles, and especially in the caulked areas. Sprayed it on, let it sit, then scrubbed it with a battery powered scrubber. It did a great job, brightening the entire shower. I did this while actually showering, which makes it easy to rinse off. No overwhelming smell.

This stuff is a godsend. I had mold/mildew stains in a shower that did not come off when I used regular scrubbing bubbles foam, let it sit, and then scrubbed with a brush. I was super disappointed. So I tried this product as my last hope, and it worked great! The pictures are from after scrubbing with the other product and then after using this product. It's like night and day. The stains were already gone after I let it sit for 5 minutes before I even scrubbed it with a brush. The pictures speak for themselves. Highly recommend for mold and mildew stains. I also used it in my bathroom sink for the orange ring around the drain that didn't come off with multipurpose cleaner. It helped that too. Great product.

Very effective
Works great in a timely manner.
