RMR-86 Instant Mold and Mildew Stain Remover Spray - Scrub Free Formula, 30 Fl Oz

I wish I would have taken before and after photos!! I tried a few cheaper products that did nothing! So finally decided to spend a little more and it works just as advertised! After 15 minutes the mildew was gone and i didn't have to scub at all! The smell is really strong! So make sure to ventilate, but definitely buy this one!! I just bought the two pack and gave one to my mom and she is also very happy!! The spray nozzle is kind of flimsy, I do wish that was better. I'll probably have to buy a spray bottle to transfer is into at some point. But the product itself works amazing!

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 bought this product for 2 bathroom projects:1) I had a hole in the wall near the pipe under my sink that was leading to humidity in the under sink cabinet and mold on the inside of the cabinet door/items in the cabinet2) I had old, cracked caulking around bathtub/shower in the same bathroom that had gotten mold/mildew from water being able to get into itI had tried MANY things to get the mold/mildew off of these surfaces. Vinegar, Bleach, recipes off Pinterest, and pretty much every bathroom cleaner or mold and mildew remover that you can buy at the grocery store or target. Nothing worked. It might get a little off, but minimal improvement even after soaking and scrubbing.Then I decided to give this a shot based on the Amazon reviews and I’m so glad I did! It came packaged securely (which I was glad a lot because I imagine it’s pretty toxic). The application was easy, just spray and let sit. I will say, after you spray this, while the area is soaking, make sure you run the air vent, open a window if possible, and leave the room. The chemical smell is intense and honestly doesn't feel safe to inhale for very long. I also wore a mask, but just a cloth one from the days of peak covid. Return after letting it sit, and I can almost guarantee that your mold and mildew will wipe right off if it isn’t already gone and disappeared just from sitting there. In extra tough areas I did reapply a second time just to be extra sure it was all gone since this was part of a project stripping old caulking and applying new.Bonus: the size of this bottle came with far more than I needed for these 2 projects. I could easily do another room in the house if needed with the amount included. I definitely recommend this product!

Works great on all kinds of stains.Only problem is spray handle does not work until the last . I had to change the bottle for the spray handle every time .Hope they can improve this.

If I could give more stars I would. Cannot believe how well this product worked on mold spots on the walls in my basement. Simply spray on, leave for a few minutes and I rinsed off with a wet cloth. Strong smell but its a smell that you know is clean! Can’t wait to try it for my shower doors!

I never write reviews but i had to rate this one.This is the best product. Works great. Removes the mold. Wear gloves and a mask. It smells horrible and its very very strong but it does the job well. It might take 2-3 applications overnight for 2-3 days and the mold disappears.Highly recommend this product.

I don’t usually write reviews, but this one deserves it! We bought a pontoon that had seats in horrible condition. We tried everything! Last thing I tried was this and I wish I had found it sooner! I mean instantly when it’s sprayed on it melted the mold, mildew, stains away! Absolutely amazing product! A before and after of the magic!

This worked well. The odor is very very strong. Smells like it's bleach based. However, we plan on painting in the bathroom and this helped get rid of any mold on any surface. Spray, walk away, rinse and your done. Make sure room has ventilation and wear gloves, mask and goggles. I will say it's worth the money.
