Cleaning Chemistry and Foam Control

The chemical in the solution tank decides as much about the result as the brush, the pad or the machine. The right product at the right dilution lifts soil and dries clear. The wrong one dulls floor finish, etches stone, leaves a sticky film that makes floors slippery and dirty again by the next day, or fills the recovery tank with foam that slips past the float and damages the vacuum motor. The guides in this section cover the chemistry side of auto scrubbing in practical terms. Start with the floor cleaner pH guide to match pH to the soil and the floor, then use dilution ratios for the ounces per gallon math and worked tank fills. Neutral cleaners explains the daily default, degreasers and heavy soil covers grease, oil and double scrubbing, and defoamers and foam control explains why defoamer belongs in the recovery tank. You will also find guides to testing and removing residue, green cleaning certifications, and chemical-free scrubbing. One rule runs through every page: follow the chemical's label and Safety Data Sheet, and the machine maker's chemical compatibility guidance, before anything goes in the tank.
