RMR-86 Instant Mold and Mildew Stain Remover, 1 Gallon

I used this to remove ugly black mold buildup on the white painted wood railings of my front porch. I've tried so many other products but they just didn't do the trick. I tested this with high hopes from the good reviews I read, and I was pleasantly surprised! I'd say 90% of the test area cleaned right up after applying and letting it sit for about 15 seconds. But this was years of build up, so I'll do a second application and see what happens. I'm very happy with the results already, however. Even using it outside, it still had a strong bleachy smell, but that's okay. I would recommend this for sure.

Quickly and thoroughly removed black mold from painted walls inside a closet. Made the basement walls which had a gray mold on them look like they had just been painted when in fact it has been 20 years. Even took mold off a vinyl window shade with no scrubbing or scouring. Still waiting to try it on bare wood but have every reason to think it will eradicate all traces of mold. I am going to be ordering the preventative spray to try after the treatment to help keep from recurring. Very pleased with this purchase and the value. Only drawback is the heavy chlorine odor, but I used a paint respirator the second tie and made sure to ventilate the area well.

I have tried it on some old Molds around the shower and kitchen sink. The effect is amazingly fast , in few seconds it took care of many stains, some old stains required 2 or 3 applications, but this product beats everything else I have tried by far>

This stuff here it's amazing it works like magic. I would recommend this product to everyone. It does a wonderful job. It's literally one and done. I definitely recommended this to all my family, friends and coworkers.

If you are in an enclosed spaced wear PPE. This stuff is serious business. It will for sure get the job done. It's pretty cool how you can actually watch the stains go away.

This is amazing stuff. There was so much green mold on my parents deck from lack of sun and too much moisture. I got myself a spray bottle and sprayed it down real good and wow it worked like magic. Truly incredible stuff. Highly recommend it!!

this is an amazing product that works wonders..not only does it remove that icky green mold on my white walls but it works quickly and even on rough surfaces the stain is gone by the next day..and I have tried lots of other products..this one is the best

PROFESSIONAL STRENGTH!!! It is potent. It doesn't say to dilute it but I did and it was still a strong smell in the air. Probably should of worn breathing apparatus cause i was feeling uneasy. Had to ventilate the whole house to clear it out. But, it did a really good job

Works very well and quickly. I use on vinyl window frames. Much better than any others Ive tried. This actually works!

I had high hopes for this product, but ended up very disappointed. It claims that you just spray it on and wipe it off and the black mold stains will come off. It states that in some cases where the mold has been there for some time, it may require some light scrubbing to get it clean. I sprayed and scrubbed three or four times, scrubbing hard, but the stains are still there in the caulking, almost the same as before using the product. I sprayed and let it sit for a while, hoping that time would allow some stain removal, but no such luck. Now I have most of a gallon left and little hope of being able to make the shower ever look clean again. Sorry, Bob Villa. If this is your %231 product for removing mold, I am left without hope.
