RMR-86 doesn't ask you to scrub — it just goes to work. Spray it on black mold staining across drywall, deck boards, vinyl siding, brick, or concrete, and the discoloration starts lifting almost immediately, which is the part that surprises most people the first time they try it. 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.

Biocide 100 goes after the stuff most household sprays just wipe around: mold, mildew, fungi, bacteria, germs, and viruses.

It doubles as a general-purpose cleaner, so you're not juggling three different bottles under the sink. Fair warning: this is a disinfectant first and a polish second.

Scrubbing grout lines until your arm aches is apparently optional now, because APULITO's cleaning gel does the work while you get on with your day.
