The 32-ounce ready-to-use bottle covers a lot of ground, and since the formula is aimed at the ugly stains mold leaves behind rather than the mold itself, it works best as part of a proper cleanup routine. Ventilation and protective gear aren't optional here. The spray is potent, so plan on a mask, gloves, and open windows. Twenty minutes with a fan beats an afternoon of scrubbing.
