Magic spray

Brad HoffmanMay 1, 2025✓ Verified purchase

This product is magical. I tell you my DIY friends about how it effortlessly cleans stubborn mold stains. Use this product on outdoor pvc railing to make it perfectly clean without any scrubbing. It works on composite decking. I've tried powerwashing the railing and deck with no results, this spray makes all the difference. I've also use this product in my tiled shower as it removes all signs of soup scum, no scrubbing required. If you have any pool swimmies or plastic toys left in a damp environment with mold spots they will disappear but the bleach may also change their color. The fumes after spray are very strong. I recommend wearing a mask even when applying outside. It's not worth injuring your throat, lungs. I've heard others wear gloves. I only wear gloves for bigger jobs. Bottom line. Add this to your set of tools. Every house should have a bottle. Read more

Eliminates mold and stops it from coming back!

John BOctober 18, 2025✓ Verified purchase

This is an outstanding product!!! I had received a FB ad for a similar type mold removal product. I found this brand on Amazon and decided to go with the pro version. We have a tile and glass shower and have been dealing with black slimy stuff in the corners for the last few years. Even after cleaning, it never looked that great. I mixed this up, sprayed it in the bottle and it virtually all went away but for one corner I'm going to retreat. What's better is it has stopped the mold from coming back. I also had some green mildew on our front porch that I treated with this and it went away as well. Read more

Best mold removal product on market!

BubbleboyDecember 6, 2025✓ Verified purchase

This product is nothing short of a miracle. Bought some 60’s vintage wicker furniture and the original cushions had black mold spots on a very delicate fabric, otherwise in great shape. Really wanted to keep the pieces original we tried all the standard cleaning remedies for mold, borax, baking soda & vinegar, etc.. I was ready to give up ehen I found this product on Amazon. The effectiveness was evident immediately. You know you have the right stuff when the dirt starts to disappear almost instantly. No harsh smell and completely removed the mold and other stains. Bought this size after using smaller bottle as we know we’re going to use this on everything. Don’t waste time and money on anything else as this is far and away the most effective spray product on the market! Read more

Fantastic product

GPERUFebruary 6, 2026✓ Verified purchase

I have been using for years. Absolutely the best. I just figured out using it on my outdoor furniture molded fabric, works great and doesn't bleach the fabric. I only wish I would have tried that a lot sooner. Read more

Worked Fantastic — But Definitely Not a DIY Job!

STNovember 14, 2025✓ Verified purchase

Worked Fantastic — But Definitely Not a DIY Job! This mold and mildew remover worked fantastic. It cleared everything up way better than I expected and did exactly what it promised. The results were impressive! That said… I would not recommend doing it yourself. The fumes are strong, and it’s definitely one of those jobs that’s better left to a professional if you can. Great product — just use caution! Read more

Amazing product. Do not hesitate. Its the real deal.

LJXKJune 24, 2025✓ Verified purchase

This stuff is what you wish all other products were. This actually works. So well, it does the job itself. Sprayed it and it was gone. It’s cleaning power is unmatched. The smell is like you’d expect, but not insanely overwhelming either. You don’t feel like you are going to instantly die if you are not wearing a mask as you spray it. I have only had this stuff for two days, so far, it is very durable, as in .. once it’s gone, it does not grow back. The packaging is great too. Typical gallon jug, with extra internal cap sealers so even if cap came off, it would not leak in transport. Once you remove that, your only defense to spillage is using the actual cap, which works great. I poured this stuff into a spray bottle. I only had a small issue… but then I decided to clean everything with it…. For fun. Nothing else to do. My house has never been cleaner. In the past I tried all the stuff in stores. It barely does the job, tones of elbow grease (as they say) and it doesn’t completely solve the problem. Then I found this stuff while doom scrolling….. and Amazon had a fair price. I went for it, and here we are today. I help review this product on Amazon reviews as 5 stars. Honesty, if this stuff does not work, you probably need to cut the part of your house out, burn that chunk of your house, and rebuild that area. Read more

Truly Amazing - Wish I found it sooner

Ed T.January 25, 2026✓ Verified purchase

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. Read more
