What can and cannot be put in a garbage disposal?
Do's: Boneless meat, pitless fruit, bits of food
you scraped off dishes before/while washing
Don't's: Noodles, chicken skin, mashed potatoes, rice,
banana skins, potato skins, avocado skins, fruit pits, bones.
Teabags: the strings on the teabags have a tendency to wrap around
parts of the unit and may in fact trap food, which might clog your
disposal. It may also indirectly affect your dishwashers
performance (if the two units share a connection).
There seems to be some controversy over whether or not eggshells
can be put in the disposal, some people say you can, others say you
can't. I think it's an "at your own risk" thing, because I do it
and haven't had a problem, but I don't do it on a regular basis. I
wouldn't want it to malfunction and wind up footing the bill for a
busted disposal. since people have their own opinions, fyi, eggs
shells do sharpen the blades of the disposal or just add the scraps
into a compost bin and use next year on your plants.
