Importance of Cleaning Garbage Disposal

A garbage disposal unit is designed to help your home deal with waste effortlessly, meaning less strain on your plumbing. Unfortunately, if you don't take proper care of your garbage disposal, it can become a real hazard.

Without proper maintenance, your garbage disposal can quickly become blocked, meaning it will use more water and not work effectively. After some time, there will be a buildup of waste within it, which can lead to a bad smell in your home. Bacteria can easily develop if waste isn't flushing clean, making your whole kitchen unhygienic. This is a real risk in a space where you prepare food for you and your family.

All good plumbers advise that you regularly look after your garbage disposal because preventing the issues is easier than dealing with them afterward. For the best results, you should be cleaning your garbage disposal regularly.


Frequency of Cleaning

Daily Maintenance

How often you clean your garbage disposal will be influenced by how often you use it; however, regular cleaning is essential. You should look to use warm, soapy water (specialized antibacterial spray is best) and run it through the system. This should help you remove any waste and keep it smelling clean.

Weekly Maintenance

Your weekly maintenance is absolutely crucial to maintaining your garbage disposal. You should look to take an old toothbrush and scrub around and inside your garbage disposal. You can also throw in some ice to help clear out the system. To deal with a foul-smelling garbage disposal, try putting some orange or lemon peel into the unit.

Monthly Maintenance

Every month you should be doing a deep clean of your garbage disposal to keep it in the best condition and stop any bad odors. On top of your weekly scrub, you should look to use a mix of baking soda and vinegar. This will bubble up within the garbage disposal, and the acidic properties will help dissolve any blockages and remove bacteria. After about 5 minutes, follow this up with plenty of hot water and thoroughly rinse it out.
