Some of my favorite ideas:

1. Deodorize your garbage disposal: The garbage disposal drain can get stinky. Instead of pouring bleach down there to kill the bugs causing the odor (which can put off noxious fumes that make you cough), consider tossing a few lemon rinds down the disposal. This will help neutralize the odor naturally.

2. Polish metal: Nix the expensive, harsh chemicals and polish your flatwear and pans with a half a lemon and a little elbow grease!

3. Sanitize your microwave: Microwaves can get gross fast. The acid in lemons can zap germs and leave a fresh sent.

4. Blast soap scum: Um, this is brilliant: Juice six lemons and pour the contents into a spray bottle—the citric acid will dissolve soap scum!
