Vinegar deodorizes

Keep your garbage disposal running properly and odor-free with this simple once-a-month trick: Fill an ice-cube tray with white vinegar, and when frozen, grind about a dozen cubes. The ice sharpens the blades while the vinegar deodorizes the drain.

Salt as a de-greaser

Pour ½ cup salt down the drain of your kitchen sink with warm running water. This simple step will freshen your drain and keep it from getting bogged down with grease.

Make a drain volcano

Most people know the old science fair project of mixing vinegar and baking soda to cause a chemical reaction worthy of a model volcano, but not many know that this powerful combination is also a great drain cleaner. Baking soda and vinegar break down fatty acids from grease, food, and soap buildup into simpler substances that can be more easily flushed down the drain. Here’s how to do it: Pour 2 ounces baking soda and 5 ounces vinegar into your drain. Cover with a towel or dishrag while the solution fizzes. Wait 5 to 10 minutes, then flush the drain with very hot water. Repeat until your drain is clear.

Use Alka-Seltzer

Kitchen sink clogged up? Skip the commercial drain cleaners, which contain harsh chemicals that can destroy your pipes. Instead, slip three Alka-Seltzer tablets down the drain and turn on the hot water for just a few seconds. The tablets will fizz up and get to work on the clog. After 15 minutes, run the water again and the drain should be clog-free.

Baking soda hack

Instead of throwing away baking soda when it’s finished its 30-day stint in your fridge, dump it down the garbage disposal with running water. It will keep your disposal fresh, too!
