- Grease, Oil, or Fat
Oil, grease, and hot, liquid fats shouldn’t even go down your drain much less your garbage disposal. When hot oils cool down, they harden and solidify in your drain.
- Starchy, Stringy Vegetables
Celery, rhubarb, asparagus, artichokes, chard, kale, lettuce, potato peels, and other stringy, fibrous, starchy veggies. They aren’t easily broken down and can wrap around and plug your disposal.
- Pasta and Rice
Pasta and rice expand when they come in contact with water. This either causes clogs or fills up your disposal trap.
- Coffee Grounds
They seem to go down perfectly fine, and many people swear that coffee grounds can help your drain stay clean. But they can bind together and cause damage and plug your drain. Instead add your coffee grounds to the compost or sprinkle it around your garden. Coffee stimulates your plants and repels slugs, ants, and other pests.
- Paper Garbage
Contrary to the name, don’t throw garbage down the garbage disposal. That includes scraps of paper, paper towels, cotton balls, wipes, and scrub pads.
