How To Make Homemade Carburetor Cleaner

You should be aware of the proper substances to combine when producing your own carb cleaning. MEK, acetone, xylene, propane, toluene, and ethylbenzene are the main components of the carb-cleaning solution.

Note: Additives are among the ingredients found in cleaning solutions for carburetors. Acids, organic, and inorganic chemicals like benzene and toluene are included in the list. As a result, mixing cocktails can harm other carburetor components.

Here, we have given 6 methods to make your own carb cleaner. Let’s dig into it and clean it carefully!

Method 1: A blend of methylene chloride or MEK or Acetone

To get started with this method, you can soak your carburetor in acetone. Then, mix it with diesel or gasoline for it to deliver a long-lasting result. Next, you can use a soft brush to get rid of the residue. Then, leave it to dry.

 Method 2: Use alcohol, acetone, Xylol, and paint thinner

Here you’ll need at least equal parts of alcohol, acetone, Xylol, and one-gallon paint thinner. Mix the ingredient in a container and submerge the carburetor. The advantage of this blend is that it dissolves the residue or the gloss that forms on the carburetor. Like other methods above, you can use a wire brush to clean the residue.

  • Alcohol alone is a weak solvent and may not adequately dissolve the varnishes or gums that form in your bike’s carburetor or the passages.
  • However, you can mix with either acetone or Methyl Ethyl Ketone, or Xylol, or use paint thinner.

Method 3: Use Methyl Chloride and kerosene

The following method involves mixing methyl chloride and kerosene in a container. First, ensure you have a high concentration of methyl chloride, which will work as the paint thinner. It should be highly concentrated so that the kerosene mixes well. Next, submerge your carburetor and the container overnight. Ensure it’s super tight for better results.

Method 4: A blend of MEK and alcohol or Xylene

A mixture of MEK and alcohol or Xylene can make an excellent carburetor cleaner since it dissolves residue build-up.

Method 5: Use brake cleaning solution

Another option is to use a brake cleaner. The advantage of this product is that it has a unique formulation that dissolves the grease or grip from building up. Thus, it works ideally, just like commercial carburetor cleaners.

Method 6: Aerosol carb cleaner

Q. Can vinegar clean a carburetor?

Yes. Some riders use vinegar since it’s readily available and affordable. To get started, dismantle the carburetor. Next, fill the back with vinegar and ensure the carburetor is fully submerged.
