Yes, for most household molds. White distilled vinegar is effective against approximately 82% of mold species, including many common household types. Its acidity penetrates the porous surface to kill mold at the root, unlike bleach, which often just “bleaches” the color while leaving the roots alive. For particularly moldy areas, spray it undiluted and soak the mold, let it sit for at least an hour, then scrub and wipe clean.
