Your garbage disposal is one of the hardest-working appliances in your kitchen. With proper care and maintenance, it can last 10-15 years. Learn what to put down your disposal, what to avoid, and how to keep it clean and odor-free.
How Your Garbage Disposal Works
Contrary to popular belief, garbage disposals don't have blades. Instead, they use impellers mounted on a spinning plate to grind food waste against a grind ring. Understanding this helps explain why certain items can damage your disposal and why regular maintenance is essential.
Do's and Don'ts
DO Put In
- Small food scraps
- Soft fruits and vegetables
- Cooked meat scraps (small amounts)
- Ice cubes (helps clean blades)
- Citrus peels (freshens disposal)
- Small amounts of dish soap
DON'T Put In
- Grease, oil, or fat
- Coffee grounds
- Egg shells
- Pasta, rice, or bread
- Fibrous vegetables (celery, corn husks)
- Bones or shells
- Non-food items
Why These Items Cause Problems
Grease solidifies in pipes causing clogs. Coffee grounds accumulate and create sludge. Pasta and rice expand with water. Fibrous materials wrap around the impellers.
Proper Operating Procedure
- Run cold water first - Start running cold water before turning on the disposal
- Turn on disposal - Flip the switch to start the motor
- Feed food gradually - Add food waste slowly, not all at once
- Keep water running - Continue running water for 15 seconds after grinding stops
- Turn off disposal - Switch off the disposal
- Run water extra - Let cold water run for another 10-15 seconds
Pro Tip
Always use cold water when grinding food waste. Hot water can melt fats that will re-solidify in your pipes.
Cleaning Your Disposal
Weekly Cleaning
Keep your disposal fresh with this simple weekly routine:
- Fill disposal with ice cubes and a cup of rock salt
