Review: Quite literally took the black mold completely away in about 30 seconds. All I had to do was spray it. No scrub no mess. Does have a very strong smell and will irritate your lungs.
Review: This stuff was really amazing! Instantly cleared mold/mildew. I did wear gloves, and N95 mask/safety glasses. Fumes not too bad. We did have fan in window. The warnings are scary, but with proper gear, it is highly recommended.

## Questions & Answers

**Q: Does this work on porous materials?**
A: We used it to removed the algae/mildew from vinyl siding. It worked really well however we did have to saturate it heavily.

**Q: How long after use can the room be used again?**
A: I used it on boat seats and used it the next day. I have not used the product on interior items.

**Q: Do I need special protective gear to use this?**
A: Some work areas like outdoors are already well ventilated, so skin and eye protection are mainly needed. Especially indoors, 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.Please let us know if you have any further questions. Thank you.

**Q: Can I use this on my  travel trailer with aluminium factory painted siding**
A: You should not use RMR-86 on aluminum as it is corrosive to metals. Please contact us with any further questions. Thank you!
