RMR-86 Pro is a contractor-grade solution designed for rapid stain oxidation on porous surfaces like attic wood and drywall. This "Pro" variant features a higher concentration of active oxidizers and specific hybrid stabilizers, allowing it to work significantly faster than standard retail bleach. Its surfactant blend is engineered to help the solution reach deeper into the roots of organic growth than traditional household cleaners.
The product is packaged in an industrial-thickness HDPE gallon jug, which is built to handle gas expansion and prevent "bloating" during storage. However, once the induction heat seal is broken, the resulting outgassing can affect nearby metallic objects if stored in a confined space. Practical reality also shows that the high concentration of sodium hypochlorite can be extremely taxing on standard sprayers; users often find that third-party trigger mechanisms may fail if not specifically rated for corrosive chemicals.
Due to the aggressive pH (12.0 to 13.0) and high VOC levels, the use of a respirator and active ventilation is strongly recommended. While it offers unmatched "no-scrub" efficacy for heavy-duty projects, it will pit aluminum and degrade nylon fibers almost instantly upon contact. This is a powerful tool for serious remediation, provided the user is prepared for its industrial strength.
If you prefer a more controlled, gel-based application for smaller indoor areas like bathroom caulk, the HIHWEM Mold Remover Gel may be easier to manage.
