Garbage disposal Maintenance Tips
Keep your garbage disposal running efficiently with these expert tips
Run Cold Water While Grinding Food
Always run cold water before you start the disposal and keep it running for 15 to 30 seconds after you shut the unit off. Cold water keeps the motor from overheating and moves debris down the drain line instead of leaving it to dry inside the housing.
Flush Monthly With Ice and Salt
Toss a handful of ice cubes and a tablespoon of coarse salt down the disposal and run it for about 30 seconds. The ice scours buildup off the grinding ring and plate, and the salt scrubs residue from the chamber walls.
Avoid Fibrous and Starchy Foods
Celery, artichoke leaves, potato peels, and pasta wrap around the grinding plate or expand in the drain line and cause jams. Keep these out of the disposal entirely and scrape fibrous scraps into the trash before rinsing the rest.
Use Citrus Peels for Odor Control
Grinding a few lemon or orange peels once a week cuts odors at the source by releasing citric oil that breaks down grease film inside the chamber. Avoid commercial deodorizer tabs — many leave a waxy residue that attracts buildup over time.
Never Use Hot Water While Running
Hot water melts grease and lets it flow into the grinding chamber as a liquid, then it re-solidifies further down the drain and creates blockages. Use cold water exclusively while the disposal is operating so grease stays solid and gets cut apart rather than coating the line.
