When to Use Rubbing Alcohol (Isopropyl)
Reach for rubbing alcohol when cleaning electronics, mirrors, stainless steel, and tools. Its fast evaporation makes it ideal for surfaces that cannot get wet. Also great for removing adhesive residue and degreasing small areas.
When to Use Hydrogen Peroxide
Use hydrogen peroxide for bathroom disinfection, laundry whitening, removing blood and organic stains, and sanitizing cutting boards. Its oxygen-based action makes it safer for food-contact areas and environmentally friendly cleaning routines.
