$2 FORGOTTEN Liquid KILLS ALL Mold. PERMANENTLY. No Bleach. No Contractor. They BURIED This in 1952.

Main summary

Key takeaways

Science and Nature

Scientific concepts, discoveries, and nature/microbial phenomena

Mold biology and why bleach “doesn’t work” long-term

  • The visible black/green material on surfaces is described as the fruiting body.
  • The living fungal network extends below the surface via hyphae into porous materials such as:
    • drywall
    • wood
    • grout
  • Bleach (sodium hypochlorite) is described as:
    • killing/oxidizing organic matter at the surface quickly (chlorine “consumed almost instantly”)
    • delivering water deeper into materials, potentially supporting survival/regrowth by reaching the hyphae

Therefore, the claim is that bleach mainly sterilizes the top layer, while moisture/chemistry does not reach the deeper fungal network effectively enough for lasting remediation.

Borax / borate chemistry as antifungal protection

  • Borax (sodium tetraborate decahydrate) dissolved in water forms an alkaline solution with pH ~9.3.
  • The video claims many mold species prefer acidic to neutral pH (about 4–6), so pH 9 is outside optimal growth conditions for many indoor molds.
  • Boron compounds are claimed to also act directly on fungi by:
    • disrupting enzyme function
    • inhibiting spore germination

Prevention vs remediation

  • The video distinguishes:
    • prevention: making materials hostile before colonization
    • remediation: removing existing colonies

Evidence base from wood-rot and indoor molds

The video cites USDA Forest Products Laboratory research indicating:

  • Borate compounds alone strongly inhibit wood decay fungi, including:
    • brown rot
    • white rot
    • (fungi that destroy structural lumber)
  • Against common indoor species like Aspergillus and Penicillium, borates alone show weaker results.
  • Performance improves when borates are combined with fatty acid compounds, per the cited studies.

Key takeaway presented

  • Borax is effective as a preventive barrier, especially for porous/wood materials.
  • However, it may not “eradicate everything” inside deeply infested drywall without physical removal.

Industry/system claims (codified standards and incentives)

The video argues that:

  • Building codes and professional remediation standards emphasize:
    • physical containment
    • source removal
    • not borate prevention for homeowners
  • It attributes this omission to financial incentives, including:
    • code committee representation by manufacturers/trade groups
    • remediation certification ecosystems and related business models
  • It also claims antifungal borate chemistry is already used in commercial products, but not widely marketed as a low-cost homeowner prevention approach.

Methodology / how-to described (borax use)

Mixing

  • One cup of borax dissolved in one gallon of hot water
  • Stir until fully dissolved

Application

  • For small areas: spray bottle
  • For crawl space joists/attic sheathing/basement walls: pump sprayer
  • If visible growth exists:
    • scrub with a stiff brush first
    • then apply the borax solution
  • Do not rinse
  • Let it dry in place so residual alkaline borate remains

Intended role

  • Create a residual alkaline layer to resist future fungal colonization

Caveats

  • Topical vs deep penetration
    • Not like pressure-treated lumber; does not penetrate as deeply
  • Water-soluble
    • May wash away with ongoing moisture intrusion—fix leaks first
  • Existing deep infestation
    • Deep infestation in drywall may require cut-out and replacement
    • Borax is positioned as prevention/treatment of materials that will be kept/used
