Mold & Mildew Stain Remover by RMR-86, 32 fl oz – Contractor Grade Instant Cleaner for Bathroom, Shower, Tile & Grout

Absolutely amazing! I tried everything I could think of to get black spots off the caulk in the old shower. Bleach, vinegar, and I even tried toilet bowl gel, none of them removed the mold stains. I bought this, and I couldn't believe how quickly it removed every spot! Now the smell is very strong! Be sure the room is well ventilated when using. I'm so very happy to have found this product.

I regrouted my shower 4 years ago and thought I would have to regrout again due to mold and mildew. a friend recommended this. sprayed in dry shower in morning, ran errands and came back. in less than 2 hours, mold and mildew are gone. rinse off and leave fan running. strong chlorine smell, used vinegar to dissipate smell for an hour. rinsed off again and shower is like brand new and has no strong smell.

North East Florida... north facing walls and overhang always get mold on caulked areas. (Do NOT buy Sherwinn Williams 'mold proof' caulk - worthless) This product IS bleach based, so be sure to wear eye protection, old clothes and decent spray mask...... but within minutes it knocked the mold and mildew completely back all the way through the caulk.... no scrubbing... just wet cloth or sponge to wipe off...

I recommend this highly, literally sprayed, washed my hands turned around and the mold was gone, only bad thing was even with all the doors and windows open and fan, the smell made me sicker than a dog. Other than that, this is like Mr.clean on steroids

This stuff is AMAZING! I was skeptical because the mold on my old window in my bathroom was BAD and stained the window and i tried everything from bleach to vinegar to norwex etc and was about to get the window replaced because it was so bad but i found this stuf and holy crap! litterally took the mold and stains off completely and withing like 45 seconds! It looks like i painted the window frame thats how good it worked! Definitely recommend! It does have a strong bleach smell and the bottle leaks where it sprays but those are the only cons.

I saw this on YouTube, and ordered it as a sceptic. I've always used X14 in the past, and wasn't sure about trying something new. I am happy to say it worked fantastic! I used it on my tile shower. I didn't have to do any scrubbing. I sprayed it on, let it sit awhile, rinsed it off. Anywhere remaining spots got sprayed again. Its the best my shower has looked in a long time. One of those products I wish I'd tried sooner.

This stuff worked for mold spots on bathroom ceiling. They are gone. Worked better for me than vinegar or bleach. The smell is AWFUL but small price to pay for the end result in my opinion. More pricey than other brands I found online but I am satisfied I chose this one because it actually got the job done. I sprayed, let it sit for a few and wiped away. Easy, peasy. Just be sure to wear a mask. It was harsh on the nose and eyes.

I have used everything I could find to get rid of the mold and mildew in my shower. I have scrubbed and bleached and used white vinegar and baking soda. You name it, I have tried it. I stumbled across this product. Folks, this did the job! I did not use it in great quantities, and was really careful about the fumes, they are strong! But it worked and I am so pleased!

I would encourage improved packaging for shipping as my bottle arrived with a small hole in the seal and a bit had spilled out into the cardboard box. Used some that very day and there was a noticeable difference in the area. However, the spray nozzle trigger becomes stuck when spraying. The smell of chlorine can become strong (teen grandson asked why it smelled like a pool). The product is great, just these other items were the issue.

it did nothing, except it did do damage to my caulking. It softened it and it started to come off. I have used bleach before and other mold and mildew removers and never have this problem. The bleaching in this is milder than others I have used. It must be another chemical made to adhere it. I bought it because it said 15 seconds.
