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

This stuff works amazing for removing algae off white vinyl fences, you spray it on and you just see results in seconds. For the more hard to get off ones you may have to apply a second time in a 10 minute span but this RMR is worth every penny. I have also personally used this in a shower also to remove mold and tuff grim. Works like a charm, make sure to wear a respirator and have good ventilation to not breath in this chemical.

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.

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.

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.

This product works pretty good, however it DOES NOT KILL MOLD! It removes the staines.You have to use a different product to actually kill the mold. Also, if you’re a contractor be careful using this on framing, as it is corrosive and if all your nails/other metal component's aren’t galvanized then you could have issues.

So darn easy! Wow what a difference this made on our deck rails. Spray on and leave a few seconds, we did use a soft brush too bc it was so many crevices. I think I’ll be finding more things to clean now. Watch clothing bc it will bleach it. My husband found out the hard way. 😊highly recommended. Does have a chlorine smell but outside it was not bad. Watch your eyes in case it blows- safety glasses needed.

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!

If you need to get rid of the stains from mold.....this is the product you want!!!! Unfortunately I tried a couple other products (total waste of time and money!) Then, after being totally frustrated from lack of results.... I came across a few reviews of RMR-86 Pro.....thought...what the heck...give it a try.Awesome product....works as advertised. PPE is mandatory, especially if working in a crawl space. Bleach smell, but not totally horrible.Buy this stuff, you won't regret it.
