"I WILL buy this again! I wish I had taken before and after, the "after" pic means nothing if you had no idea how bad the "before" pic was. I will truthfully say this stuff works, and it works extremely well. Well worth the price and the container is bigger than I thought it was. I have plenty left for future "situations". The smell was no different than the many other attempts of pouring straight bleach on the problem. Just pop a window open and turn on a small fan if bleach smell bothers you. The result is well worth the minor inconvenience of a light smell of bleach! Easy to use. Gel clung to the problem spot until it was gone."

"Amazing! I am blown away. I had this for a few weeks under save for later. I deleted it last week due to a few negative reviews. Also, my machine is 13 years old and I thought there is no way this will work for mine because it is bad. I even had bleach in the spot with no luck. So, I thought it was a waste of money. Fast forward to black friday week and this thing popped up in my feed at half off. I said let me take a chance. I bought it and followed the instructions. I let it sit for 6 hours and BOOM! It actually worked. So, so sorry I didn't take pics. In summation, IT WORKS!"

"This stuff is awesome. Most the caulking around my apartment tub had turned black. I used several other things on it with no luck. Applied this, went out of town for a week, came back and it almost looks like it did when I moved in. I simply brushed off the residue and ran the shower for a minute. No cleanup! You’ll need a full bottle for a full size tub. And you’ll also miss spots or need some touch ups, so maybe order an extra. I’m ordering more now."
