Don't throw away lemon peels. Use them to make a cleaner.

Lemon peels contain antibacterial properties, so use them to make a household cleaner, using the herb vinegar method, opposite. Steep lemon peels in vinegar for 3-4 weeks. Strain and use straight on glass surfaces, such as shower doors and toilets. For more delicate surfaces, such as wood benchtops, dilute with water. This mix also makes an excellent fly repellent on kitchen benchtops and window and door frames.
