10. Grease, Oil, and Fat
The tricky thing about grease, oil, and fats is they may look like liquid now, but they don’t stay that way for long. These materials will congeal with time, which can cause a major blockage in your drain. It’s best to simply allow these substances to cool, and then dispose of them in a trash can.
11. Non-Food Materials
The name “garbage” disposal can be a little misleading. It does not mean you should treat your disposal like a garbage can. Any non-food items including paper towels, plastic wrappers, or tissues can be a big problem for your drainage system. Not to mention these items can spread through your drainage system and deposit into your local water supply. If something isn’t biodegradable, it shouldn’t go down the disposal.
