RMR-86 Pro Instant Mold Stain & Mildew Stain Remover (1 Gallon)

The item worked as advertised. It was the best item we've used so far to clean mold and mildew on our patio pavers. As it has been a few years and it was quite bad, 1 gallon only cleaned a portion of the job. We also found that we needed to go over the area with a light spray and did brush the surface with a firm scrub broom. For future cleaning, if not allowed to get so bad, it would clearly not need as much effort. I will be purchasing more of this product as it really does work well. My only complaint was not with delivery but with the packaging. While the gallon does have a seal, it doesn't hold the contents well and it leaked in transport. The box the rmr 86 product is in has arrows and is clearly marked as to which was up. The Amazon warehouse placed the box containing the 1 gallon jug on its side into another box along with other items I ordered. There was a sticker on the outside indicating a liquid was in the larger box but no directional indication. The product leaked. Ate through the inner box and was starting to soak the outer. Thankfully nothing was ruined

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.

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.
