RMR-86 Pro Contractor Grade Mold Stain & Mildew Stain Remover Cleaning Solution, Professional Quality Formula, 1 Gallon

This is absolutely an excellent product. I have spent lots of money to remove the mold and mildew in the shower. I live alone, and I don't have the energy to bend and scrape. I sprayed the liquid on the built-up mold and mildew, and it was quick reacting, for the mold and mildew disappeared. My bathroom looks new. This product is by far the absolute best item I have purchased from Amazon. I was so impressed that I immediately went to the local hardware store, asked for the manager, and told him to stock this product, for homeowners will thank him!

This is the best product I ever purchased. Just pour into a chemical spray bottle, spray and watch all that mold and mildew come off so easily. I used to follow all these ideas about using baking soda and vinegar, mold/mildew removal products, scrubbing, …. Nothing worked no matter how much scrubbing I did except for RMR-86 Pro. I highly recommend it to anyone who wants to save time and money. Don’t believe all the hype you read or watch on YouTube for cleaning, this is the mother of all product I highly recommend. Please be aware, the product has a strong chemical odor. You will need to let it air out for at least two days or more and with good ventilation. I had the luxury of doing this since no one would be around for days.

This product actually works Removed mold stains and black streaks and shoe scuffs on inflatable boat.

Works so well. Wish i knew about this sooner

It is a great stain and mildew removing product however in transit the jug got damaged and had a nasty leak. ruined the boxes and I lost much of the product. When I tried to report it they wanted me to ship it back to them. Here's my question... If they can't ship it to me without it getting a leak how am I supposed to send it back with no box and have it not leak more? Whatever... I am just keeping the 12 ounces there is left in the jug and moving on with my life. The product is amazing and I love it. Don't breathe in the fumes, it is strong. I will purchase again and hope they package it better next time.

This stuff works!! I had old, black colored mold in my shower caulking and this pulled it right off like it was never there! I also used it for mildew staining on my hot tub cover and it got that off too. I had tried so many products on both of these problem areas and nothing made a difference, so this stuff is a miracle worker!

Hands down the best cleaner I’ve ever used removed mold and mildew from my rv with just a brush no scrubbing removed all the bugs too careful though when I got all done the front of my clothes were bleached terribly

So I think it’s a pretty good product for removing algae on surfaces outside like the sidewalk, rocks, or driveway. It def. works, I would say give it a full minute on surfaces such as the ones I listed vs 10 seconds. I read other reviews that said the product works in seconds which wasn’t my experience. Now on to removing mold. Well that’s why I gave it a 3 dow it lift the mold yes, but my experience has not been that it totally removes it. I have applied several applications to a wooden cabinet and it has lifted the mold in certain spots, other parts are still black, and it def. chipped the wood. I’ve applied the product at least ten times in one day. I let it sit the first time for probably a hour and then after that I reapplied every 40min-1hr. It also has a bleach smell but not as strong as other customers have written. I would recommend wearing goggles as the fumes did cause my eyes to sting a little but I wouldn’t describe what I experienced as burning. Gloves and old clothes were recommended as well from other reviews which I too recommend, and old clothes. I wouldn’t purchase again but I’m not upset at my purchase bc I do plan on using it outside again but I don’t think it’s going to completely remove the stain, even after scrubbing it.
