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 Botanical after RMR-86 Pro to eliminate any left over odor from the stain remover.
