What Never to Mix
Keep bleach entirely separate from vinegar or ammonia to avoid dangerous gases. Do not store hydrogen peroxide with vinegar in the same bottle; they can form peracetic acid, a strong irritant. Steer clear of casual cocktailing just to “boost power.” Instead, apply products sequentially with rinses in between. Use gloves for extended scrubbing, keep fresh air moving, and read labels. When in doubt, choose the simplest formula, respect dwell time, and trust small, repeatable steps to produce safer, sparkling, dependable results.
