1. Add a cup of peroxide instead of bleach to a load of whites. If there are protein stains, pour it directly on the spot, let it sit for a minute, then rub it and rinse with water. 2. Use peroxide to clean mirrors. No smearing. 3. Use 3% for removing blood stains – especially if fresh. Pour directly on the spot, let sit for a minute, then rub/rinse with cold water. ½ c. hydrogen peroxide + 1 t. ammonia = great stain removal combination.
