Help Plants Grow
Hydrogen peroxide releases oxygen, and plants need oxygen to grow; therefore, hydrogen peroxide can help your plants. To help your plants, mix one teaspoon of 3% hydrogen peroxide and one cup of water. Pour it into a bottle and spray it onto your plants. If you plan to spray your entire garden, increase the mixture to 35% hydrogen peroxide with the water. Since hydrogen peroxide kills fungi and germs, spraying this onto seeds while they’re being planted can also help them grow quicker and healthier.
Clean Rusty Tools
Have no fear if you open your toolbox and discover your favorite tools are starting to get rusty; you can scrub that away! Take a brush or steel wool scrubber and rub the rust after it has been sitting in hydrogen peroxide for a few minutes. To make this work even better, mix in some Borax with your hydrogen peroxide. Though the hydrogen peroxide should not react negatively with brass, aluminum, or metal, you may want to test it out on a small area of your tool before submerging it completely.
