Mix your ingredients in a large glass measuring cup.
Pour in a glass spray bottle – dark glass or covered with a dark bag- and store it in a dark place at room temperature to help the peroxide last longer.
Gently shake before each use.
If tackling a liquid stain, blot as much of it as possible first.
Spray and let the solution sit for about 5 minutes.
Scrub with your finger, a soft brush, or a rag.
