Garbage Disposal Cleaning

A garbage disposal mounted beneath the kitchen sink is a popular feature for many homeowners, as the machine breaks down food scraps and remnants and sends them down the drain. However, owners should schedule regular disposal cleaning, as not doing so can cause damage to the unit. 

You can find some simple steps to cleaning it below.

Ice water and salt

In a container, mix salt with ice water. Then, turn on the garbage disposal and keep it running while pouring the mixture into the sink. The salt will clean the disposal by dislodging debris sticking to the surface. Next, peel some lemons or other citrus fruits. Throw these peels into the garbage disposal and let it run for a while. This will improve the smell of the disposal.

Baking soda

Another solution is baking soda, as this substance doesn’t damage the plumbing. First, plug the drain temporarily and fill the sink with warm water. Pour about 1/4 cup of baking soda into the water and mix well. Wait for the baking soda to dissolve completely. Then, unplug the drain to allow the mixture to flow through the running garbage disposal, which will dislodge stubborn particles and make the appliance clean again.

Avoid using harsh chemicals

While bleach or drain cleaner sounds like a better solution, garbage disposals don’t work well with these cleaning agents. As such, it’s not recommended to pour these down the appliance as they may damage the plumbing.

What not to put in the disposal

Part of garbage disposal maintenance is knowing what shouldn’t go through it. Certain foods may clog pipes and cause severe damage later on.

  • Celery and banana peels are considered stringy vegetables and fruits, and they tend to get tangled around the garbage disposal blades. It will be troublesome to clean it later on, and if neglected, the peels will cause jams.

  • Starchy foods such as potatoes, beans, and rice can turn into sticky and stubborn sludge, which, over time, will clog the drain and pipes. Clearing it will likely require professional assistance.

  • Coffee grounds will eventually harden and become sediment, another cause of clogged pipes.

  • Large seeds and pits can break the disposal blades.

  • Pasta and rice swell when submerged in water, clogging pipes and drains over time.

  • Grease can build up and clog the pipes.

Regular maintenance of your garbage disposal will help it serve you for years to come. However, if there are serious issues, it’s best to contact a professional plumbing company for help. They can help solve the problem and even detect any underlying conditions.
