2. However, egg shells can be useful in the garden! Crushed egg shells can be sprinkled around plants to deter pests like slugs and snails. The sharp edges of the shell irritate the soft bodies of these creatures, keeping them away from your precious plants.

3. If you’re looking to clean and sharpen the blades of your garbage disposal, instead of using egg shells, try using ice cubes. Running ice cubes through the disposal helps clean the blades and remove any buildup, while also sharpening them.

4. While egg shells should be avoided in the garbage disposal, coffee grounds are often recommended for cleaning and deodorizing the disposal. Coffee grounds act as a natural abrasive, helping to remove any lingering smells and keeping your disposal fresh.

When it comes to disposing of leftovers, pasta is one item that should never find its way into your garbage disposal. The problem with putting pasta in the disposal is that it can easily become tangled in the blades. The sticky nature of pasta, combined with its long strands, can cause a clog in the disposal or even damage the blades. Additionally, pasta expands when it absorbs water, so if it gets stuck in the disposal, it can cause the unit to malfunction.

Contrary to popular belief, garbage disposals are not designed to handle bones. The powerful blades in the disposal may be able to grind up small chicken or fish bones, but larger bones such as beef or pork can wreak havoc on the system. The tough and dense nature of these bones can dull the blades, leading to decreased functionality and potential damage. Additionally, bone fragments can get stuck in the disposal’s pipes and cause blockages.

Therefore, it is best to dispose of bones in the regular trash or use them for other purposes, such as making broth.

Coffee Grounds

Many people are surprised to learn that coffee grounds should not be put in the garbage disposal. While they may seem harmless, coffee grounds can cause a variety of issues when disposed of in this way. The coarseness of the grounds can create a sludgy paste that clogs the disposal’s pipes and drains. Additionally, coffee grounds can accumulate in the trap beneath the disposal, leading to unpleasant odors. Instead of putting coffee grounds down the disposal, consider composting them or adding them to your garden as a natural fertilizer.

Potato Peels

While potato peels are biodegradable, they can still pose a problem for garbage disposals. The starches in potato peels can clump together, forming a thick paste that clogs the disposal’s blades and pipes. This can lead to decreased performance and potential damage to the unit. It is best to dispose of potato peels in the regular trash or find alternative uses for them, such as making potato skins or using them in compost.

By understanding which items should not be put in the disposal, such as pasta, bones, paint, coffee grounds, and potato peels, you can ensure its longevity and prevent costly repairs. Follow these guidelines to keep your garbage disposal functioning properly and to maintain a healthy plumbing system for years to come.
