If you are in the habit of throwing out lemon peels after making lemonade, it is time to make a change. The citrusy fruit skin has antibacterial qualities that can remove stains and odours. You can use it to brighten surfaces, appliances, furniture, and linens. Some ways to DIY cleaning agents with lemon are lemon-infused vinegar (2 cups of lemon peels + 4 cups of white vinegar), lemon scrubber (lemon juice + salt), and lemon steam air freshener (lemon juice or peels in hot or boiling water).
