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

I can not say enough good things about this product! Does exactly what it says. What sold me was a customers review video where he sprayed a bad mold spot and it disappeared without rubbing in less than 10 seconds. That’s exactly what it does. It’s pretty versatile too. We have this white fence that’s essentially plastic but it looks good anyway it was covered with greenish/brown spots from hurricanes kids lawnmowers etc spraying it and who knows what else. and there was actual mold in some tighter places. anyway I used an adjustable spray bottle and was able to cover it all pretty quickly and before I even finished I could see the pure solid white where I started. Then I tackled the back of the fence that was somehow more covered in grass/dirt/whatever.. like twice as bad especially where our hedges cover some of it. that needed two different sprayings but was no competition for this spray. My fence looks Brand new 🤩I also have a garbage disposal that gets used very often and for whatever reason it always starts to smell after a few days..no matter how well you rinse it. But I spray this in the garbage disposal every single night and the smell hasn’t come back and I’ve been using this for at least a year ..every night just a couple sprays straight in the garbage disposal. I try to cover the sides because I don’t know if you’ve ever looked at the underside of them but… It’s gross. I also use it in my showers, and since I used it the first time when it got everything off, nothing has come back. Maybe a little soap scum every now and then but nothing bad. This is an incredible product. they say to wear a mask. I don’t I just hold my breath, but I probably should. obviously it’s a very serious chemical so you want to be very careful. Somehow it always gets on my hands.. it doesn’t burn but it’s the consistency of bleach and it’s hard to get off the the way bleach is.

Does exactly what is in the description. Was able to remove mildew stains that I thought would never come out, after trying everything else. It’s been a year since I first started using this product to get rid of mole stains around Windows inside my Florida home. The stains cleared up right away and they haven’t come back. I would expect them to come back eventually. When it does, I will treat them again. Like everyone else in the reviews, I recommend using a good respirator when using this product and keep your room or area well vented until the smell can dissipate. It’s a very very strong chlorine/bleach smell.

I was apprehensive about making this purchase but I am soooo glad that I did. I live in a house with painted cement walls so I was concerned about how this product would interact with everything. Fortunately, everything worked perfectly! I used protective gear as advised and then applied the product onto my walls with a garden sprayer. After 20 minutes, the mold stains were completely gone. No exaggeration...COMPLETELY gone. This product is an answer to prayer!

Why did you pick this product vs others?:I have used this product for a few years now. It absolutely kills molds and fungi and the best part, they don't come back!I have used multiple products before RMR86 and some may get rid of the mold but they all come back. Worth the price.

What I didn't expect was a 15 minutes chore to open the jug. Darn near gave up and was going to drill a hole in the bottle before one final "push and turn." Was annoyed to have to disrobe from my gear because I got too hot trying to open it.I used the product in a spray bottle on a dry North facing surface that was getting a little mold build up. After 10 minutes of sitting and soaking I pressure sprayed and wiped it down. It's only been a couple weeks since doing that. So I don't know yet how long that results will last.I wore an old PVC rain coat with hood on and fitted safety glasses during a south wind day. It was definitely needed as it smelled pretty chemically even outdoors with a good breeze. Mainly smelled like a heavy Clorox.One star off because cap was probably messed up for why it was so difficult to open. It looked fine and the product was also bagged in the shipping box. Hopefully I'll be able to open it easier next time. 🤞🏻

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.

Smells awful- use ventilation (as expected). This worked wonders! We bought a 30 yr old home and the shower grout lines were black in several areas and even some green algae on the glass block window edges along the inside of the glass. My husband cleaned it all out in one day with this stuff. The grout lines look new, no traces of black. We had previously tried scrubbing them with various over the counter products but nothing else worked. It did take another day and half to get the odor out of the house after finishing but we opened the windows to speed that up. Def. will use this again.

If you want sodium hypochlorite to kill mold and mildew, then buy a gallon of laundry bleach at a retail store. You will get the same active ingredient at less than one-third the price.
