Watch RMR-86 PRO Remove Mold in Seconds!

RMR-86 Pro is a more aggressive mold and mildew stain remover than the original RMR-86. This new integrative formula is designed to last longer and is five times stronger than any mold and mildew stain remover on the market today. The new RMR-86 Pro is a mold stain cleaner that utilizes special deep penetrating surfactants with Hybrid Ultrapure Sodium Hypochlorite™ which creates a deep-cleaning action that breaks apart stains, dissolving them quickly and easily, while removing the ugly mold/mildew stain color. Having trouble removing mold stains? No problem with this ready to use product that requires no mixing, just shake well and apply with a standard pump up sprayer or our 110 Electric bucket sprayer. Watch those deeply embedded fungal stains disappear within seconds. This contractor grade formula will now give you at least 10 months of shelf life, if not more. Start saving even more and use less with RMR-86 Pro. If you are still hand sanding, soda blasting, or using any other chemical other than RMR-86 Pro, you are wasting thousands of dollars in not only product cost but labor cost as well. Last but not least, don’t forget to apply RMR-141 RTU to kill the mold after RMR-86 Pro. Pick up the phone today or go to our distributor locator page to find product near you.

  • REQUIRED SAFETY PRECAUTIONS: Before starting application, make sure you’re wearing full PPE.

On average a 32 oz bottle covers about 60 square feet and a 1 gallon covers about 200-400 square feet. This can vary based on the severity of the affected area, as well as how liberally the product is applied.


Unfortunately, RMR Solutions is unable to state that this product actually kills mold due to not having an EPA registration number. We have been told from numerous contractors from their proven tests, that this product did in fact kill the mold spores.


Mold can certainly grow back after using any type of mold product out there. The key to keeping mold from growing back is making sure you correct the issue in which mold is able to grow. Keep in mind if there is humidity relatively above 50% or any kind of moisture on a substrate, mold can grow. Use RMR-86 to remove those ugly stains and make sure you fix the moisture problem to prevent mold from fully coming back.


A direct spray is required for the RMR-86 to work properly. Using a trigger sprayer on the bottle for small jobs, or a pump-up sprayer or an electric sprayer for larger jobs. Using on a rag is also acceptable in some cases. Make sure you shake product vigorously prior to applying as well.


Yes, but some work areas like outdoors are already well ventilated, so skin and eye protection are mainly needed. We still always recommend wearing full PPE when applying RMR-86. This includes a hooded tyvek or a chemical poly coated suit, full face respirator with P100 organic vapor and acid gas cartridge filter and latex gloves.


RMR-86 is Sodium hypochlorite-based, which can be hazardous without proper equipment and precautions. In addition, mold stain cleanup environments are already hazardous, and precautions should always be taken.
