Overview

• New how-tos detail a paste of three parts baking soda to one part 10-volume hydrogen peroxide with a toothpaste-like consistency for grout, tubs and cookware.
• Laundry guidance advises applying hydrogen peroxide to stains, sprinkling baking soda, resting about 30 minutes for colors or up to an hour for whites, then washing.
• Experts explain peroxide supplies oxidizing and antimicrobial action while baking soda adds gentle abrasion for scrubbing without harsh chemicals.
• For peroxide and vinegar, outlets instruct using separate spray bottles, applying hydrogen peroxide first and vinegar second, never premixing, then wiping surfaces.
• Precautions include avoiding marble, testing on small areas, and leveraging the low cost of ingredients reported locally to replace pricier commercial cleaners.
