Garbage Disposal Care and Maintenance
A well-maintained garbage disposal can last 10-15 years. Learn how to keep yours running smoothly and avoid costly repairs.
Proper Use Guidelines
What You CAN Put in a Disposal:
- Small amounts of soft food waste
- Fruit scraps (except fibrous fruits)
- Vegetable trimmings
- Cooked meat scraps
- Ice cubes (helps clean blades)
- Citrus peels (freshens and cleans)
What You Should NEVER Put in:
| Item | Why It's Bad |
|---|---|
| Grease and oil | Solidifies and causes clogs |
| Coffee grounds | Accumulates in pipes |
| Egg shells | Creates granular waste that sticks |
| Pasta and rice | Expands and causes blockages |
| Fibrous vegetables | Wraps around blades (celery, corn husks, asparagus) |
| Bones | Can damage blades and motor |
| Fruit pits | Too hard for blades |
| Non-food items | Obvious damage risk |
Daily Best Practices
- Always run cold water - Start before turning on disposal and continue 15 seconds after
- Feed gradually - Small amounts at a time, not large quantities
