Remember though to keep it working; you will need to run it a few times even when you don’t want to use it just yet. Also, proper maintenance is necessary if you’re going to keep it free of rust.

It’s not every day that your disposal will rust, but if you neglect it you expect it, must rust.

Reasons for The Garbage Disposal Rust

  • The material

Most of the garbage disposal is made using steel. If you don’t let the disposer dry out, the presence of oxygen allows it to rust if it doesn’t correctly dry up after use.

  • Cleaning

If you don’t clean the disposer nicely, it will begin to get the damage. Rust is one of the problems you may experience with the disposal.

  • Connection

Some parts of your disposals like the sink flange will have the seal deteriorate. When this happens, you will need a plumber’s putty to re-fix it.

Sometimes even the mounting ring or gasket is cracked or damaged.

If the disposal has a hole that lets in water, it will soon begin to rust.

How to Remove the Rust in The Garbage Disposal?

The things you need

  • Lemon
  • Salt
  • Ice cubes


  • Begin by mixing a cup of lemon with three tablespoons of salt. Stir the mixture well before you can begin the process.
  • After you have finished cleaning the food waste, run some water to clear up any food residue lagging.
  • Go on to pour the mixture above into the garbage disposal. Also, let it set into the disposer overnight. Remember you aren’t supposed to run water in the garbage disposal when the lemon mix is in the disposer. That would dilute the content.
  • After 24 hours, you can then release the content to the drain as you clear any more food waste that could be hanging on. Run some cold water into the disposal.
  • Finally, grind ice cubes to get rid of possible gunk and dirt in the disposer. You can turn on the garbage disposal and the water to help in the grinding. After this, it should be perfectly clean.

This should let the garbage disposal work well. If it still isn’t working well, you can use the following method to clear any clog.

How to Remove the Clog Using Baking Soda and Vinegar?

You will need a cup of baking soda and a cup of vinegar. Begin by pouring the cup of baking soda then the cup of vinegar, and as it foams, then it will remove the clog.

It should take you a few minutes. After that, you can follow in with the hot and boiling water, and that will clear the clog further.

To finish off, grind some lemon pieces to deodorize the garbage disposal. Lemon not only removes the bad odor but also helps you get rid of the stuck rust.

Prevention of The Rust in The Disposer

The way to prevent rust is mostly by choosing the right blade material. Instead of the regular steel, you can select the stainless steel, and that will prolong the development of the rust.

Also, keep washing it after use and use a lot of the lemon solution to clear and prevent the formation of rust.

Never let it go for so long without use.
