Does Hypochlorous Acid Kill Mold?

Yes, hypochlorous acid (HOCL) effectively kills mold on contact. It's EPA-registered as an antimicrobial proven effective against all common mold species including black mold (Stachybotrys), Aspergillus, Penicillium, and Cladosporium. HOCL works by disrupting mold cell membranes, denaturing proteins, and preventing reproduction. Unlike bleach, it penetrates porous surfaces to kill mold at its source.

Yes, significantly. HOCL is 80-100x more effective than bleach at killing pathogens while being completely non-toxic. Bleach only cleans surface mold and cannot penetrate porous materials where mold roots grow. Worse, bleach adds moisture that actually promotes mold regrowth on wood and drywall. HOCL penetrates surfaces, leaves no toxic residue, and helps prevent regrowth.

Yes, HOCL is one of the safest antimicrobials available. It's the same compound your immune system produces naturally to fight infection. HOCL is non-toxic, produces no harmful fumes, and is safe for people, pets, and children. The FDA has approved it for food contact surfaces. You can re-enter treated spaces within 1 hour, unlike traditional mold treatments.

Yes, hypochlorous acid effectively kills black mold (Stachybotrys chartarum). HOCL eliminates black mold spores on contact and can help neutralize mycotoxins - the harmful compounds black mold produces. For extensive black mold contamination, professional treatment is recommended, and our HOCL application may be combined with physical remediation depending on severity.

HOCL kills mold spores on contact - the action is essentially instantaneous. For professional treatment, we apply HOCL and allow a dwell time of 15-30 minutes for complete coverage and penetration into porous materials. The entire treatment process for most homes takes 2-4 hours, and spaces are safe to re-enter within 1 hour of completion.

HOCL treatment helps prevent mold regrowth, but it's not a permanent barrier. For lasting results, moisture control is essential since mold needs moisture to grow. We recommend combining HOCL treatment with proper ventilation, humidity control, and addressing any water intrusion issues. Maintenance treatments every 3-6 months can provide ongoing protection in high-humidity environments like Georgia.

While consumer HOCL products exist, professional treatment is far more effective. Professional-grade HOCL is more potent, and we use specialized fogging equipment that ensures complete coverage and penetration. DIY treatment risks incomplete coverage, inadequate concentration, and failure to identify all mold sources. For significant mold problems, professional treatment is always recommended.
