Review: Works great as I am cleaning to repaint all interior rooms of our house! - We waited far too long to fix up mildew spots in a various locations around our house (mostly its on our louvered doors and a few other doors, and in bathroom cabinets / shelves / closets... Anyways, this spray is great. It is STRONG smelling, and I don't like the spray so we have our own method: a) wear eye protection, gloves, mask b) pour the solution into some plastic handheld containers c) use a sponge to lightly dip and then rub over the areas to clean them I find we use less of the solution and it's more accurate than just spraying. It definitely cleans up the mildew spots, sometimes not fully (some had been there a long time and really stained the paint) but for me that is OK as we're cleaning, scrubbing and then I'm repainting everything inside the house anyways. recommend also, if you repaint, use some paint that has some mildew/mold resistance. not sure how much it helps but it can't hurt. but yeah, strong cleaner! just go slow, and be safe, and it works like a charm.
Review: FORTUNE & GLORY - Ok, seriously, if you’re brave AND a home owner, BUY THIS. 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!

### ⭐⭐⭐⭐⭐ Great great at cleaning mold, chlorine smell fades away after 2 days
*by T***N on December 18, 2025*

My bathroom had these old mold stains that started peeking from underneath a coat of paint that the previous owner had put, which started to come out with vengeance. Multiple members in my family take really really hot showers and leave tremendous amount of steam on the walls and the surfaces. RMR-86 cleaned them all. Including the mold that was inside the calking, leaving the whole place shining and very clean. Only one bad thing about the product is the STRONG chlorine smell that lingers around for days. Advice to close the bath room doors properly and open any windows, spray vinegar mixture after application and wear mask while applying the product. Inspite of the strong smell, I've given 5 stars because of the cleaning performance and how quick it was!
