If you are looking for an eco-friendly and resource-light way to eliminate bloodstains and other protein-based stains, look no further than your trusty bottle of hydrogen peroxide.
Last weekend, Little Cheap got a bloody nose at a friend’s house. She brought home with her a shirt splashed with blood stains that had sat overnight. Yikes …
Luckily, hydrogen peroxide came to the rescue. I have seen instructions for making stain removing pastes to get rid of the blood. But I simply dampened the fabric and drizzled some peroxide on the blood. Where there was blood, the peroxide turned into satisfying fizz. I rinsed the shirt (with lovely rusty water coming off the cloth) and threw it in the wash. Good as new!
You can also use peroxide to remove pet stains on hard surfaces and stains on counters. It’s one of the options for removing perspiration stains. And mixed with dish detergent, it apparently takes out wine stains, too.
