What’s Safe to Go Down a Disposer?

InSinkErator food waste disposers are designed to handle a wide range of food waste. Here’s a guide to what’s safe, what to avoid, and why.

What’s safe to go down a disposer?

What you can put down

  • Fruit and vegetable scraps – peelings, cores, seeds and skins
  • Cooked and uncooked meat scraps
  • Chicken and fish bones
  • Egg shells
  • Coffee grounds and paper filters
  • Tea bags without strings or staples
  • Avocado skins and stones
  • Citrus rinds – great for freshening the disposer
  • Bread and grains
  • Small amounts of dairy

What to avoid

  • Fats, oils and grease – these solidify in pipes and cause blockages
  • Large bones from beef or pork
  • Fibrous vegetables in large quantities – celery, corn husks, artichokes
  • Pasta and rice in large amounts – they expand with water
  • Non-food items – plastic, glass, metal, paper
  • Harsh chemicals and bleach – unnecessary and damaging to seals

Simple habits for best performance

  • Always run cold water while operating the disposer and for 30 seconds after
  • Feed waste gradually rather than all at once
  • Freshen the disposer regularly with citrus rinds or ice cubes
  • Never use hot water while grinding – it can cause grease to liquefy and recoat the pipes
  • When in doubt, feed it gradually and keep the cold water running.
