Hydrogen peroxide has many uses. You probably have a dusty brown bottle in the back of your cabinet. Pull it off the shelf, check if it’s 3-percent grade and use it around your home. If you don’t have any, it’s cheap to buy and great to have on hand.
Here are a few ways to use it:


De-skunk a pet:

Combine one quart hydrogen peroxide, 1/2 cup baking soda and two teaspoons Dawn dishwashing liquid. Wet your pet’s fur and lather the mixture like shampoo. Leave the mixture in for 10 to 15 minutes and rinse.


Works well as a bleach alternative and to remove stains. For bloodstains, wet the stain with hydrogen peroxide and sprinkle baking soda on it. You can apply the hydrogen peroxide and baking soda a few times until the stain lifts. One reader, Karen, shares: “I use this all the time as a stain remover on light-colored clothes and it works great. I dab it on with a Q-tip or cotton ball, depending on how large the stain is, and rub gently. Hydrogen peroxide is a mild bleaching agent, so you might not want to use it on darker-colored clothing unless you test first in a discreet spot to make sure it doesn’t fade the color. If the stained area is really large, I would soak it in water with 1/4 cup or so of hydrogen peroxide added and see if that loosens the stain.”

Sanitize surfaces:

Mix one part peroxide with one part water and pour into a spray bottle. Clean countertops, mirrors, bathroom and cutting boards, or use as a vegetable wash. Works well to clean insulated lunch bags, too. Don’t store mixture. Only mix what you’ll use that day. Another reader, Jeannie from Pennsylvania, shares: “For mold or mildew in the bathroom, mix one cup peroxide, one cup white vinegar and two tablespoons baking soda. Mix ingredients and pour into a spray bottle. Be careful when pouring into bottle, as it will foam up.”


Using one teaspoon of peroxide to one cup of water in a spray bottle, spray your flats to speed germination and prevent damping off. Another reader, Kim from New York, shares: “Peppers are notoriously tricky to get started because they require continuous warmth and humidity. I set up a fluorescent shop light under my cupboards to provide light to my seedlings. I moistened a paper coffee filter and put my seeds on it, then folded it and put it into a little plastic container with a lid, which I placed on TOP of the light fixture. It is just the right temperature to get the seeds started, and boy, do they grow quickly! This can also be done in plastic zipper bags. Check daily to make sure they are still moist and to make sure there is no fungus or anything on them. I like to use a water/peroxide solution on my seedlings. Once they have sprouted, pull them out of the filter and plant them. I went from no peppers to more peppers than I need with that one little trick. Works great for all sorts of seeds, and I’ve even let some seedlings grow like this all the way to leaves without any ill effects. You can do this with flowers, too, and if you want them very closely spaced (small plants or ground cover), just plant the filter along with the seeds. Also works with paper towels, but I prefer the filters as I like to remove the seedlings and the filters don’t come apart as easily.”
