RMR-86 Instant Mold and Mildew Stain Remover Spray - Scrub Free Formula, 2 Pack - 32 oz

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!

I wish I had taken a before photo. I used this in my shower and the caulking all looks band new and not like I’ve lived here 10 years. It’s beautiful and worked super fast with zero scrubbing. I sprayed and walked off for a while and then just came back and rinsed it off with my shower head. I did get a bit I my shirt and it bleached a spot so definitely be mindful using in nicer clothing or with pets or small children around. It had a mild bleach scent so I did use my bathroom vent to circulate air. Easy and effective!

This stuff works great! We had some surface mold starting in our garage on the walls and this stuff cleaned it up right away!! It was like magic, it just disappeared with such ease. I wish it was a bit more affordable, but with the ease of use and speed it works I can understand. Highly recommend!!

Product works well on mold and mildew stain removal, but the chemical smell is very strong with the scent of bleach.Make sure you wear rubber gloves to protect your hands, a facemask to prevent throat irritation and safety glasses.Make sure you use it in a well-ventilated area for safety.

I was SHOCKED at how effective this spray is. I sprayed it on the rubber casing of my front load washing machine and some inside the drum itself. Ran the tub clean cycle and went to bed. Woke up and thought to myself “this spray was probably another waste of money.” I was shocked when I flipped open the rubber casing and saw that it is 85% gone. I am going to keep using it to remove all of the mold. NOTHING has ever worked to get rid of front loader washing machine mold and mildew. I was ready to just give up and get a top loader. I’m truly blown away at how effective and fast this product worked. Warning: it does smell like a powerful bleach agent. This is not a paid review. Just a truly amazed mom who had to share!

This stuff is incredible.Our garage doors developed mold because the previous owners covered up the ventilation (idiots) and we live in the PNW of the USA. I did a ton of research on the best products to clean, kill, and prevent mold. Eventually, I selected and purchased 4 different products, including this one. I tested each one, side by side, on the same door and let them dry overnight. Now I can’t speak to the prevention of mold since it’s only been 12 hours, but this product did an amazing job of removing the stains without damaging the paint on the door - and it worked almost instantly. Literally before I even finished spraying the last product (within 30 seconds).Products tested in this experiment (from left to right)1. MOLD ARMOR Mold Blocker Spray2. 30 SECONDS Pro Mold and Mildew Stain Remover3. RMR-86 Instant Mold and Mildew Stain Remover4. Concrobium Mold ControlPlease note that the picture below shows some white spots on #2 - but they are just small bubbles and went away shortly.I didn’t notice a huge difference in the results between this product (#3) and the 30 SECONDS PRO (#2), but the spray on this product wasn’t that great to use. “Stream” and “spray” were very similar and the trigger didn’t recoil fully and product #3 was a much better experience. The other product also states clearly that it didn’t require rinsing, which is a huge bonus, where this one does require rinsing.I give this product 9.5/10.I suppose it’s possible that the other products would work on other types of mold and it just so happens that my mold was highly susceptible to #2 and #3. If this product doesn’t work for you, that is the only reason I can think of.I’ll be leaving this same review (or similar information) on the other 3 products.
