What to soak a carburetor in?


When it comes to cleaning a carburetor, soaking it in a suitable solution can be an effective method. Soaking helps to remove dirt, debris, and built-up deposits that can hinder the carburetor’s performance. However, it is essential to choose the right solution to ensure the best results. In this article, we will explore various options for what to soak a carburetor in, highlighting their benefits and considerations.

Carburetor Cleaning Solutions

1. Carburetor Cleaner: One of the most commonly used solutions for soaking a carburetor is a specialized carburetor cleaner. These cleaners are specifically formulated to dissolve and remove varnish, gum, and other deposits that accumulate in the carburetor. They are available in aerosol cans or liquid form and often come with a dip basket for easy soaking. Carburetor cleaners are generally safe for most carburetor components, but it is essential to follow the manufacturer’s instructions and safety precautions.

2. Mineral Spirits: Mineral spirits, also known as white spirit or paint thinner, can be an effective alternative for soaking a carburetor. It is a petroleum-based solvent that dissolves grease, oil, and other contaminants. Mineral spirits are readily available at hardware stores and are generally safe for use on carburetors. However, it is crucial to ensure that the carburetor is completely dry before reassembling and reinstalling it.

3. Vinegar: Vinegar is a natural and cost-effective solution for soaking a carburetor. Its acidic properties help break down deposits and remove rust. To use vinegar, simply submerge the carburetor in a container filled with vinegar and let it soak for several hours or overnight. After soaking, rinse the carburetor thoroughly with water and dry it before reinstallation. While vinegar can be effective, it may not be as potent as specialized carburetor cleaners or mineral spirits.

4. Baking Soda Solution: A baking soda solution can be used to soak a carburetor, particularly for removing rust and corrosion. Mix baking soda with water to create a paste-like consistency and apply it to the affected areas of the carburetor. Let it sit for a few minutes, then scrub gently with a brush. Rinse the carburetor with water and dry it thoroughly. While this method may not be suitable for heavily soiled carburetors, it can be effective for minor rust or corrosion.


When choosing a solution to soak a carburetor, there are a few considerations to keep in mind:

1. Carburetor Material: Different carburetors are made of various materials, such as aluminum, brass, or zinc. It is essential to select a solution that is safe for the specific material of your carburetor. Certain solvents may corrode or damage certain carburetor components, so always check the manufacturer’s recommendations or consult a professional if you are unsure.

2. Safety Precautions: Some carburetor cleaning solutions can be toxic or flammable. It is crucial to follow the manufacturer’s instructions and safety precautions when working with these chemicals. Ensure proper ventilation and use protective gloves and eyewear to protect yourself from any potential harm.

3. Additional Cleaning: Soaking alone may not be sufficient to clean a carburetor thoroughly. It is often recommended to use brushes, compressed air, or other tools to remove stubborn deposits or debris. Consider using these additional cleaning methods in conjunction with soaking for optimal results.


Soaking a carburetor in a suitable solution can effectively remove dirt, deposits, and built-up contaminants. Carburetor cleaners, mineral spirits, vinegar, and baking soda solutions are all viable options for soaking. However, it is crucial to consider the carburetor material, follow safety precautions, and use additional cleaning methods if necessary. By choosing the right solution and taking proper care, you can ensure your carburetor functions optimally.
