How To Clean Mold With Vinegar?
QUICK ANSWER
Clean mold with vinegar by spraying undiluted white vinegar directly on the moldy surface from a spray bottle. Let sit for at least one hour, then scrub with a stiff brush, wipe with a damp cloth, and dry thoroughly. Vinegar works best on hard non-porous surfaces and small areas.
Vinegar is one of the most popular DIY mold treatments and it actually works, though with some limits. The acetic acid in vinegar kills about 82 percent of mold species on contact and is safer than bleach for most household use. Here is the right way to apply it, when it works well, and the situations where another approach makes more sense.
Does vinegar actually kill mold?
Yes, plain white vinegar (around 5 percent acetic acid) kills about 82 percent of mold species, including most common household molds. The acidic pH penetrates the mold and disrupts the cellular structure. Important: vinegar kills mold on the surface and slightly below, but is less effective at killing mold that has grown deep into porous materials like drywall, untreated wood, or carpet. For surface mold on hard materials, vinegar is the cheap, safe, and effective choice. For deep mold in porous materials, removal of the material is the right answer.
How do you use vinegar on mold?
Pour undiluted white vinegar into a spray bottle (no need to dilute with water). Spray the moldy area thoroughly so the surface is wet but not dripping. Let sit for at least 1 hour to give the acid time to penetrate. Then scrub the area with a stiff brush. Wipe with a damp cloth to remove dead mold and vinegar residue. Dry the area completely with a fan or cloth. The smell of vinegar fades within a few hours. For tough mold, repeat the process or leave the vinegar on overnight before scrubbing.
When does vinegar work and when does it not?
Works well on: bathroom tile and grout, shower walls, sink areas, window sills, and any hard surface with surface mold. Less effective on: untreated wood with deep mold (the acid does not penetrate deep enough), drywall with visible mold (replace the drywall instead), carpet (the mold has likely penetrated the backing), and large mold infestations over 10 square feet (call a professional). For these situations, vinegar might lighten the visible mold but the mold returns quickly.
Vinegar versus bleach for mold removal?
Vinegar is safer, cheaper, and gentler on surfaces but slower-acting than bleach. Bleach kills mold instantly on contact but does not penetrate porous materials well; the surface looks clean while mold roots survive underneath. Bleach also off-gases chlorine fumes that can be harmful in enclosed spaces. For most household mold on hard surfaces, vinegar is the better choice. Bleach is appropriate for stubborn surface mold on tile and grout where the cosmetic discoloration matters. Never mix vinegar and bleach in the same cleaning since the combination releases toxic chlorine gas.
Vinegar is an effective mold treatment for hard surfaces and small areas: spray undiluted, let sit an hour, scrub, wipe, dry. Skip it for deep mold in porous materials like drywall or carpet since the acid does not penetrate. Vinegar beats bleach for safety and surface penetration but is slower-acting. The whole job takes under an hour for typical bathroom or window sill mold spots.
