How to Use an Ultrasonic Cleaner for Carburetor (Step-by-Step Guide)

I have tested all the tricks in the book to clean out clogged carburetors, but using an ultrasonic cleaner to clean the carburetor is the best. It does not matter whether I remake old parts or simply keep them in excellent condition; an ultrasonic car part cleaner has made all the changes. So, let me go over how I apply it, why it is so effective, and the machine I would recommend in this guide.

How to Use an Ultrasonic Cleaner for a Carburetor

Cleaning a carburetor with an ultrasonic cleaner is easier than can be expected, yet it is the little things that make the difference. So, here is my complete summary of steps:

1. Pick the Right Cleaning Liquid

Chemical or toxic acids are among the top liquids not to use in an ultrasonic cleaner. Instead, to clean a carburetor, apply a liquid degreaser that is a water-based solution, or directly water with a few drops of dishwashing soap. 

Some individuals vouch for specialized ultrasonic solutions or Simple Green. Simply make sure that what you use is not corrosive or unsafe to unprotected metal and alloyed aluminum.

2. Pre-Clean the Carburetor

I run a simple wipe-down, getting rid of oil and rubbish, before throwing it into the tank. The deep stuff is put into the ultrasonic cleaner, but make sure that you remove the loose dirt first.

3. Disassemble the Carburetor

Break down the carburetor: gaskets, jets, bowls, and all. The cleaner is most effective when all of the surfaces are exposed.

4. Set Up Your Ultrasonic Cleaner

• Put your cleaning solution in the tank (read fill line recommendations).
• Set the temperature between 68°F and 176°F (20°C–80°C).
• Set the timer for 15-30 minutes, depending on how dirty the part is.

If you have a machine like the Creworks 22L or 30L ultrasonic cleaner, this is very easy with knobs or the digital panel.

5. Start the Cleaning Cycle

Put your carburetor parts into the stainless-steel basket that is provided and immerse them in the bath. Press start and leave the bubbles to work their magic.

After a few minutes, you will see the dirt floating on top, and that is your indication that it is working.

6. Rinse and Dry

After the cycle is completed, I wash it all with warm water, followed by blowing with compressed air. This aids in the prevention of corrosion and makes the carburetor bone dry prior to reassembly.

Why Ultrasonic Cleaning Works for Carburetors (and Other Car Parts Too)

Carburetors have lots of little holes, associated corners, and sticky deposits. Washing by hand or dipping in chemicals is hardly effective at the core of the grime. However, when I dropped my first carburetor into an ultrasonic tank? It was perfect.

The secret is in cavitation. The ultrasonic cleaners emit 40kHz sound, directly translating to forming microscopic bubbles in the liquid. The bubbles burst and shoot off filth, even into the most inaccessible corners. It is soft, non-abrasive, and far more effective compared to brushing or soaking.

Besides carburetors, I’ve used my ultrasonic cleaner for car parts like:

• Fuel injectors
• Brake calipers
• Valve covers
• Small engine parts
• Bolts, nuts, and washers

Basically, anything metal that’s greasy, grimy, or gunked-up benefits from an ultrasonic bath.
