This is the literally the BEST product for mold or mildew i have ever used. YES, it may need to be evaluated by the Chernobyl Nuclear Assessment Team down the road, but PLEASE let me explain and leave some application pointers #1) If you're not using PPE + a respirator, make SURE you only plan to work on small patches at a time, and in a well ventilated area you can get in and out of to fresh air quickly. I cannot stress this enough. This stuff is STRONG. As in...BLEACH x about 5. You can Taste It. Do NOT BREATH IT! If you can, hold your breath, hold the bottle at a safe distance, spray the area quickly, then runaway! “Spray. Then Runaway.” #spraythenrunaway #2) Get a CLEAN towel and place it under the door crack of the room you run out of after spraying. use it, ALWAYS! Clean towel is your buddy here. #3) After 15 minutes, Hold your breath and check out your progress carefully. It dries VERY quickly and the smell/fumes drop to a good 1/2 of what they are during initial application. Again, wait AT LEAST 15 minutes before checking. More mold? Spray a bit more in the areas that need it, ...runaway #spraythenrunaway, ....wait 15 more mins and check again....same process as above. #4 Repeat protocol until about 15-25% of mold or mildew remains. #5 WAIT 2-5 HOURS then check again. At this point, the mold should be almost 100% gone. #6 IF more application needed, repeat process again as many times as needed, ....then proceed to fortune and glory. My Actual Spray Process I used on our Bathroom Window Casing: 1. Remove Blinds. 2. Cut large piece of cardboard out to use as a mask for window vinyl, steel or fibrex behind the wood casing. 3. Grab paper towels, about 10 squares and fold them into little wads that can be stuffed at the bottom of the window sill's left and right sides to catch the runoff from the vertical side casings. 4. Grab a small ziplock bag to store the used paper towels in and keep them sealed up and the fumes contained. You can just leave that in the sink. 5. Get a fan and set to low about 3 feet from the open window and blowing toward it. 6. Grab your cardboard and your RMR 86, take a deep breath, hold it....hit the left side wood casing, using the cardboard as a mask for the window behind the casing, hit the right side, same process. Do NOT try and do the top casing, or spray will potentially come back down on you and get on your skin. Don't overspray. Just hit them quickly enough to cover each side. About 15-20 seconds total should be fine. Stuff paper towel squares in the lower right and left window frame, runaway! (for me, I closed the door behind me and stuffed a paper towel under it. Worked like a charm as the smell never got into the rest of the house. 15 minutes later, I cautiously walked back in each time, smelling carefully from a distance and as I approached, as I said, the fumes and volatility drops a LOT after the first 15 minutes but is still STRONG! I removed the paper towels used to capture the runoff in the lower left and right sills, sealed them in the baggie, dropped it back in the sink. Then went outside the room to fresh air, took another deep breath and repeated step 6. Our casing was BAD, so I had to hit it about 4x over an hour. For me, and because I was doing such a small area with plenty of ventilation, I did not go full PPE or respirator. I used long dish gloves, goggles and held my breath each application, keeping the airflow via a fan pushing air OUT the wide open window and as to move any overspray or fumes outside asap. The first application, not a lot of difference. Second, BIG difference. By application 4, 85% of the mold and mildew were gone and we were looking at CLEAN wood. Next morning, I checked and the mold was 100% GONE...so this stuff KEEPS working long after that 15 minute mark. I'd say it likely keeps working up to 24 hours after application so expect to see additional progress on the affected area up to a day later. For the TOP casing, I waited until the sides were treated as explained above. Then 2 days later, I used the same ventilation setup as before. This time, I grabbed a paint brush, poured a tiny bit of rmr 86 into a plastic cup, and lightly painted it onto the top casing, still wearing gloves and goggles. It took more applications...i believe 5 or 6, but was a lot less stressful as I was using so little of the stuff and the fumes, although still bad, were no where near what spraying did. Each application, I'd let sit 15-20 mins, and I kept the paint brush and tiny bit of RMR solution in a cup in the sink so I could just grab and go each new session or dump out with running water. This worked well on the top casing as it was no where NEAR as caked as the left and right sides were, but something tells me, spraying/aerating this stuff out of the bottle must increase effectiveness, as it IS a corrosive and reacts with O2. I'd say if you're doing ANY job larger than what I described here, go Full PPE with Respirator and make SURE the room you are working out of is well ventilated and siphoned OFF from the rest of the house. If you're just squirting a few corners of your bathroom...1-2 squirts, 1 area at a time, then gloves, eye protection and lotsa of ventilation should be fine. Higher up areas, I'd recommend the paintbrush trick. And I'd personally NEVER try and spray multiple areas in the same room...I'd do 1 at a time and leave. Even a few squirts in a few areas adds up fast, and you don't want to create a potential "fume trap" by which you get a breath of lingering spray and burn your lungs/throat, etc. Not worth it! Review: Works as advertised - spray - wait 15 seconds - mold and mildew is gone - Had years worth of dark mold/mildew stains on bathroom ceiling. Put off cleaning because of hours of scrubbing required by tsp and other similar solutions. This product says spray and it works in 15 seconds. To be honest, I was skeptical. When it arrived, I sprayed a spot to test and watched the second hand on my watch - 15 seconds and the test spot was clean. My wife has done the entire bathroom and looks like new. Started with 2 32 oz bottles which wasn't quite enough so I bought a gallon. HIGHLY recommend having a window open - VERY strong bleach like scent. The smell will also take a while to dissipate but definitely worth it. As an added bonus, the product is made in USA by a veteran owned business. ## Features - GET RID OF STUBBORN MOLD AND MILDEW STAINS: Our instant spray cleaner removes the stains left behind from black mold and mildew.

Removes mold within three minutes! *by T***H on April 21, 2026* This actually works!!! I had many black and yellow mold, stains on my paint, and after spraying most of the spots just once within two or three minutes full of the stains were completely gone! I transferred this to a smaller spray bottle so I can use it in the future if needed, but I was able to use less than 16 ounces for an entire bathroom which is pretty impressive. Super simple to use just spray it and be careful. Do not stand under it if you’re spraying it on a ceiling so it doesn’t drop down on you and make sure to wear a mask as it is a very strong chemical smell. ## Frequently Bought Together - RMR-86 Instant Mold and Mildew Stain Remover Spray - Scrub Free Formula, 30 Fl Oz - Clorox Toilet Bowl Cleaner, Clinging Bleach Gel, Ocean Mist - 24 Ounces, Pack of 2 - Scrubbing Bubbles Foaming Bleach Bathroom and Shower Cleaner Disinfectant Spray, Helps Erase Mold & Mildew, 32oz --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/673078005-rmr-86-mold-stain-remover](https://www.desertcart.com.cy/products/673078005-rmr-86-mold-stain-remover) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-28*
