What is the Best Carburetor Cleaner and What’s Good About It

A carburetor cleaner is aimed to purify the dirt that accumulates during carburetor operation: layers of oil, gasoline, dust, and soot. One of the main benefits of the carb cleaner is the ability to remove pollution under high pressure. So now you know what is carburetor cleaner.

The basic element of any carburetor cleaner is gasoline or acetone. The acetone is one of the strongest solvents that can significantly soften the carbon deposits. In addition, the composition of the cleaning spray includes various chemical compounds that enhance acetone’s efficiency. For example, toluene, benzene, various acids and other organic and inorganic compounds.

They usually are sold in two forms — liquids and aerosols. The application method of these forms is different. Some cleaners require manual use while some are designed for automatic use. The liquid cleaners considered to be automatic as they don’t require human intervention. The aerosols or sprays are used manually and are equipped with a special nozzle.

The length of the nozzle allows you to spray the cleaner in the most inaccessible places. Just for the record, sprays are the most popular type of cleaners among drivers as they act very fast and doesn’t require carburetor dissembling or removing.

What does Carburetor Cleaner Do?

The carb cleaner removes deposits of different origins from jets, idle system, channels, and carburetor valves by transferring them into a soft form, after which they become easy to remove. It definitely surpasses all the alternative ways of carb purification in its effectiveness. The product quickly evaporates from the treated surface and doesn’t require rinsing with water or a degreaser.

If you use a carb cleaner correctly and on a regular base, you will notice the following changes:

  • the engine starts quicker and works smoothly at idling;
  • reduced fuel consumption; decreased exhaust gases toxicity;
  • better car performance even if you use a low-quality fuel.

However, most modern cleaners perform not only their main objective. In particular, they include additional additives and oils that provide lubrication to the carburetor moving parts. The cleaners also cover the carb parts with a protective film, increasing its service life.
