RMR Brands DIY Mold & Stain Remover Bundle, Complete Mold Killer & Mildew Prevention Kit, Disinfectant Spray, Includes 2-32 fluid ounce Bottles

We used this to clean a bathroom with this that was contaminated with ringworm from a foster cat. You definitely want to use it with proper ventilation as the smell is rather strong, however, the cleaner worked very well. It was very easy to apply, and remove. Just spray, leave on for a a minute or so, and wipe off. I left mine on for several minutes to ensure no fungus was left, but it removed easily, and it didn't stain any of the services I sprayed it on, including wood. This would be quite good for mildew application, and did actually remove some mildew from our grout in the shower. I wouldn't use this as an everyday cleaner, but its great when you have mold buildup or mildew in bathrooms, laundry rooms, etc. I would also make sure to use gloves, as again, this stuff is very strong.

I managed to purchase this because our project couldn't wait +1 week delivery from Lowes/Home Depot. Amazon offered next-day shipping. Applied RMR-141 and RMR-86 and it was HIGHLY effective at removing mold. Easy application with powerful pump. Leaves zero streaks. Dries fast. Recommended wear a mask for safety, smells like bleach. Very consistant results when applying to areas such as wood. I don't consider amy other brand to get the job done as effective as RMR

Full disclosure: I used Google's AI Gemini to generate a summary of the safety precautions needed before using these products. Do your own research and proceed cautiously. I make no claims about the accuracy of this summary. The comments in brackets are mine, not AI generated. Working with RMR-82 (a sodium hypochlorite-based mold stain remover) and RMR-141 (a quaternary ammonium-based disinfectant) requires a specific workflow. Because these products serve different purpose, one for "killing and cleaning" and the other for "removing stains", using them safely involves preventing dangerous chemical reactions and protecting your health. CRITICAL: Do not mix RMR-82 and RMR-141 in the same container or apply them at the same time. RMR-82 contains bleach (sodium hypochlorite). RMR-141 is an RTU (Ready-To-Use) disinfectant. Mixing bleach with other cleaners can create toxic chlorine gas, which is harmful or even fatal if inhaled. The Recommended Sequence: Apply RMR-82 first to remove the mold stains. LET IT DRY COMPLETELY BEFORE USING RMR-141. Apply RMR-141 second to kill any remaining spores and provide a residual barrier to prevent regrowth. Personal Protective Equipment (PPE) Since RMR-82 is a high-strength professional formula, standard "household" precautions aren't enough. Respiratory Protection: Use a NIOSH-approved respirator with acid gas/organic vapor cartridges like an N95 at minimum, but a P100 with organic vapor cartridges is highly recommended. Eye Protection: Use chemical splash goggles. Do not use standard safety glasses, as vapors can still irritate the eyes. Skin Protection: Wear chemical-resistant gloves (nitrile or latex) and long sleeves. RMR-82 is corrosive and will bleach clothing and irritate skin. [I'd suggesting using a disposable chem resistant hazmat suit. Some are in the $20 range but not from trustworthy suppliers like Dupont which charge significantly more]. Ventilation and Airflow Both products, especially the RMR-82, have a very strong odor and release potent fumes. Cross-Ventilation: Open all windows and doors in the work area. Mechanical Ventilation: Use floor fans to push air out of the space. If working in an attic or crawlspace, use a "negative air" setup if possible to ensure fumes don't drift into the living quarters of the house. Evacuation: Keep pets and children out of the area until the surfaces are dry and the odor has completely dissipated. Surface Safety & Prep Check Compatibility: RMR-82 is safe for wood, concrete, and tile but can damage certain metals or fabrics. Always do a spot test in an inconspicuous area. Protect Surroundings: Cover any items you aren't treating (carpet, furniture, plants) with plastic sheeting. RMR-82 will permanently discolor fabrics and plants. Runoff Control: Ensure that the liquid does not pool in areas where it can't be easily dried or rinsed. So, there you have it. I plan on using these products after taking the suggested precautions. Will update if it doesn't perform as advertised.

NOTHING comes close to cleaning my shower and tubs as well as this product. The bottle is sturdy with no leaking and easy to spray. It has options for stream or broad spray. It cleans the mold and mildew stains immediatley without much effort. It does have a strong odor and could possibly pose safety concerns, but that is to be expected with heavy-duty cleaning products. It has been safe to use on my tub and shower material with no damage.

This stuff worked AMAZING on attic mold. I had an insulation contractor come and look at doing blown in insulation in my attic. But they spotted some black mold and wanted a complete mold abatement before they would do any work. I looked into professional mold abatement. No way I could afford that. So I bought this premix in the spray bottles. Don’t want to get into mixing in a sprayer. I started by making and using a tyvek suit and the 86 remover. You definitely don’t want to breathe it in. Headed into the attic. Started spraying wherever I could see mold. Then ended up spraying the entire underside of the roof decking. The mold disappeared almost instantly! And these bottles go along ways. Two were enough to get all areas of concern in my 600 sq ft house. After spraying couple hours later I went up and reapplied on the trouble spots just to make sure it was all dead. Then the next day once it was all dry I went up with the other bottle that contains a fungicide and I sprayed everything again. Two coats. 2 months later the blown in insulation project is complete. The company was completely happy with how I did it with these chemicals and were perfectly willing to do the job after I killed it all. And the biggest advantage of using these chemicals is no sealing things up. The professionals hit the surface with pressurized dry ice. This requires them to seal everything and use fans with hepa filters to make sure no spores end up in the house. But this method you are just killing it in place. You are never disturbing it, so don’t have to deal with all the masking and plastic and hepa filtration equipment. And there is no risk of it escaping in the house as it’s dead in contact. Then the second spray just makes sure it doesn’t come back. I now have proper insulation and venting so hopefully will never be an issue ever again. I just rechecked several of the worst areas. It’s now a couple months later. Nothing. The wood sheathing is clean. No black mold has returned. So hopefully problem solved. The two bottles in the kit will easily treat 200 to 300 square feet of surface very well. I ended up buying 2 kits and it did all I needed with half bottles left for future if needed. So thank you to whoever makes this. In this case the expression “better living through chemistry” holds true. This stuff killed the mold instantly and appears to have sold the problem of reoccurrence. Just don’t breathe it. The first bottle, the 86, had an almost overwhelming smell. It’s strong. But I used a spray painting respirator which I fit nice and tight and properly after shaving my beard and I was absolutely fine.

This product ROCKS! I run a dog agility business and all my tunnels and tunnel bags were severely molded and I thought I was going to have to replace them. I looked up and found this product decided to give it a shot. I am so impressed with this product. It is so easy and 100% does what it says it can do. Previously we had used products and then scrubbed and scrubbed and nothing ever changed. With this product you spray it on wait literally 15 seconds and spray it off with water and my tonal bags and my tunnels are like new. The one thing I would say to remember is wear gloves it is chemicals it is hard on skin so try not to get it on your skin. The instructions tell you to suit up I think that I would take the extra caution to keep your skin safe. Will purchase this again as needed. It comes with a second jug that is to be used to keep them old from coming back, I will be using that as well in the next couple days to keep them looking great. I have no reason to think that that product won't be equally as good but I can update once I try it.

This is the strongest mold remover I’ve ever used. If you want to see years of grime that all the bleach you ever used missed, this will expose the most vile of junk on any surface it touches. No scrubbing required, but would highly recommend a mask, gloves, and probably a N-95 mask as well. Open every window you have, and be prepared to gag from a combo of the smell and the mold you watch fall off, chunks at a time with every spray. Cannot recommend this product enough for truly needed mold removal, just be so careful around kids and pets and bare skin! Open a window, or you will leave your project high.

I ordered RMR Brands Complete Mold Killer and Stain Remover Bundle—2-32 ounce sprays because I had a nasty stain on my kitchen wall (see photo). A bag of sugar snap peas had rotted at the top of the trashcan and was evidently touching the wall (don’t judge!). I thought the stain was mold, but as I used these products, I saw that it wasn’t, but rather the dried residue from the rotting peas. Here is what I did: RMR-141 Disinfectant, Fungicide, and Cleaner 1. Because I had read in the reviews about the odor of the products, I first opened the patio door and the bedroom window (we have a small apartment). I turned on the exhaust fans in the bathroom and the laundry room, and the ceiling fan in the dining room. I also placed a stand fan in the living room and one in the bedroom, and waited for about 30 minutes for the air to flow well before I started using the products. Turns out RMR-141 has no odor. 2. I read the instructions on the purple bottle, that of the RMR-141 Disinfectant, Fungicide, and Cleaner. NOTE: USE THIS PRODUCT FIRST. 3. I opened the seal and inserted the provided pump. NOTE: THE PUMP COMES IN THE “SPRAY” POSITION. BE CERTAIN TO SCREW TIGHTLY; EVEN THOUGH I DID, THE PRODUCT POURED OUT OVER MY HAND LATER WHEN I TILTED THE BOTTLE. 4. I sprayed the area on the wall thoroughly, starting at the top. The stain began running down the wall immediately. 5. I then waited for 10 minutes as per the instructions. 6. Wearing glasses, a mask, and gloves, I used a wad of paper towels and made one swipe through the middle of the area so I could see how well the product worked (see photo). I was impressed. 7. Then I scrubbed the wall. 8. I applied the RMR-141 a 2nd time and immediately scrubbed the wall again with no waiting period. Much more came off the wall. 9. I applied the RMR-141 a 3rd time and waited another ten minutes. 10. I scrubbed the wall with paper towels again. 11. I sprayed the wall with RMR-141 a 4th time and scrubbed (see photo). 12. I sprayed a 5th time and scrubbed with a thick crevice brush (see photo). I actually took the paint off down near the baseboard. 13. Then I was satisfied I had gotten the wall as clean as I could and I let it dry for an hour. RMR-86 Instant Mold and Mildew Stain Remover 1. See #1 above. RMR-86 DOES have a strong odor reminiscent of bleach. 2. I read the instructions on the green bottle, that of the RMR-86 Instant Mold and Mildew Stain Remover. NOTE: USE THIS PRODUCT LAST. 3. I shook the bottle well, as the directions stated. 4. See #3 above. 5. Wearing glasses, a mask, and gloves, I sprayed the area on the wall thoroughly, starting at the top. 6. I watched for 15 seconds, as per the instructions. There was no change. Keep in mind the stain on my wall was NOT mold or mildew, which is what this product is for. 7. I rinsed the wall and floor thoroughly with clear water. 8. To avoid the possibility of any sort of chemical reaction or contamination of other items, I put the paper towels and gloves used with each product in separate gallon Ziploc bags before putting them in the trash. Dispose of chemically saturated towels, rags, and gloves responsibly! 9. I left my apartment open to the air for two hours. Overall, I’m very happy with my purchase. The kitchen wall will still have to be painted eventually, but the performance of RMR-141 was impressive. I can’t speak to the performance of RMR-86, but if the reviews of other buyers are anything to go by, it, too, is an incredible product. At the price point of $23.99, this duo is a good value for the money. Even with the glowing reviews I read before buying, the performance of RMR-141 exceeded my expectations.
