While it ’s ok to station most soft food for thought , ice cube , chop food , and yield peels through the garbage electric pig , there are a few things that are better off in the trash can or your compost agglomerate . We tap master plumbers Roy Barnes and Hendrik Vandepoll , Centennial State - owners ofService Force Plumbingin Rockville , Maryland , for a few garbage disposal upkeep peak .

1. Fat, Grease, and Oil

While your drivel disposal can handle liquid or semi - substantial fat , grease , andcooking oil , the rest of your domicile ’s plumbery system can not . “ The full-grown no - no is grease , ” Vandepoll say . “ It may look harmless when it ’s a lovesome liquid you’re able to run through your electric pig , but it will chill apace in a dark , hidden organ pipe and become a awkward raft that can either produce a blockage on its own or grab other rubble as it passes through . ”

According to Barnes , fat cause the same problems . “ If you withdraw the extra fat off your porc roast , for example , and then mash it up in your disposition , you just make a greasy jam that can cause problem downstream , ” he says .

Delicious on your plate , but a problem in your plumbing system , alimentary paste , rice , and oats continue to swell with water , even after prepare . Toss them in the rubbish unless you ’re willing to risk a clog .

It ’s super convenient to peel spudsover the kitchen sump , but do n’t send those peels down the drain . Potato disrobe rick into a gluey masses inside your plumbing system pipes , and pose a major clog dance risk .

“ Potatoes and white potato vine Peel being put down the drainage are a big reasonableness that the Clarence Day after Thanksgiving is one of the fussy bathymetry crisis days of the class , along with grease , ” Barnes explicate . “ Your garbage garbage disposal is large at turning starchy intellectual nourishment into a sticky spate that can either clog up your pipe … or grab onto other debris as it go through . ”

6. Broken Glass or Metal

If alloy or methamphetamine hydrochloride fall into your refuse disposal , do n’t turn the appliance on . rather , cut off power to the social unit and exchange off the disposal at the social unit under the sink , then endeavor to fish out the interloping item with a fork , grabber , or hooking . If that ’s not possible , put ongloves to protect your handsand cautiously retrieve the point . Always make certain thegarbage disposalis whole turn off before endeavor to recall an item from the sink .

7. Eggshells

There ’s some difference about whether or not shell are secure for the garbage electric pig , but according to Barnes , they ’re another big no - no . You ’re better off compost them , shell them up andmixing them into your garden grease , or disposing of them in the Methedrine .

9. Fibrous Vegetables

While most vegetables can safely pass through thegarbage disposal , fibrous veggies , including artichoke , celery , rhubarb , lettuce , kale , cornhusks , onion skins , asparagus , and chard incline to get knot around the disposal ’s blades . “ These are actually hard on your garbage garbage disposal itself and can shorten its lifespan , ” Vandepoll says . Instead , deposit these veggie in yourcompost bin , or toss them in the deoxyephedrine .

10. Produce Stickers

It ’s fine to put citrus , Malus pumila , orbanana peelsinto the garbage disposal , but be sure to get rid of any produce stickers before you do . Stickers are probable to adhere to the garbage disposal ’s blades , or the inside of your pipes .

12. Fruit Pits

When you ’re snacking on fruit and are left with just the pit , deposit it in your compost or scraps . Whilegarbage disposals are generally jolly durable , this hard center seeded player will belike indent or break the blades .

13. Coffee Grounds

14. Sauerkraut

Be careful when you ’re scraping shell after a barbeque ! Sauerkraut is a delicious condiment , but it ’s also a prime offender for clogging a food waste electric pig . Like potato skins , sauerkraut will shape a gelatinous goo in the drain .
