1. Keep Insects Out of the Kitchen You don’t need insecticides or ant traps to ant-proof your kitchen. Just give it the lemon treatment. First squirt some lemon juice on door thresholds and window-sills. Then squeeze lemon juice into any holes or cracks where the ants are getting in. Finally, scatter small slices of lemon peel around the outdoor entrance. The ants will get the message that they aren’t welcome. Lemons are also effective against cockroaches and fleas. Simply mix four lemons (along with rinds) with 2 litres of water and wash your floors with it; then watch the fleas and cockroaches flee. They hate the smell.
2. Brighten Clothes Ordinary bleach can cause the iron in water to precipitate out into fabrics, leaving additional stains. For a mild, stain-free bleach, soak your delicates in a mixture of lemon juice and bicarbonate of soda for at least half an hour before washing. Diluted or straight, lemon juice is a safe and effective fabric whitener when added to your machine-washing water. Your clothes will also come out smelling lemony fresh. To remove those yellowing stains from shirts and blouses, simply by scrub them with a mixture of equal parts lemon juice and water.
3.Freshen Your Breath Make an impromptu mouth wash using lemon juice straight from the bottle. Rinse with the juice and then swallow it for longer-lasting fresh breath. The citric acid in the juice alters the pH level in your mouth, killing the bacteria that cause bad breath. Rinse after a few minutes, because long-term exposure to the acid in the juice can erode tooth enamel.
4. Prevent Potatoes from Turning Brown Potatoes and cauliflower tend to turn brown when boiling, especially when you’re having friends for dinner. You can make sure the white vegetables stay white by squeezing a teaspoon of fresh lemon juice into the cooking water.
5. Brighten Dull Aluminum Make those dull pots and pans sparkle, inside and out. All you need to do is rub the cut side of half a lemon all over them and buff with a soft cloth.
The only one I am leary about is rinsing my mouth with lemon juice....
