Factors Consider To Before Buying a Carburetor Cleaner
High Energy Solvent Technique
The best carb cleaner should come with high energy solvent technique (HEST). I find this technology to be very effective at improving fuel efficiency and vehicle drivability.
The HEST technology is formulated to clean an engine’s entire fuel system. This is from the gas tank to the combustion chamber. The tech also actively supports combustion in all grades and types of gasoline.
A car’s dirty fuel system can result in a number of engine problems, including: rough idling, hard starting, and reduced fuel economy.
There are many products in the market that promise to clean the fuel system. How do you know which one is the best? The most effective way is just to read the label.
How does HEST improve your engine performance? It is simple really. Only carb and choke cleaners with HEST technology will dissolve varnish, sludge, and gum quickly.
Carb and choke cleaners that feature high energy solvent technique lead the competition when it comes to combustion. Unlike traditional cleaners, HEST cleaners offer better combustion that improves engine performance.
Multi Fabric Content
One of the most essential features of a high performing carb and choke cleaner is multi fabric content. Engineered to clean as well as maintain the carburetor system, fuel injector, and intake valves with a single treatment.
Oxygen Sensor Safe
Is it possible to effectively clean oxygen sensors? Oxygen sensors are situated in the exhaust system, and they are usually unprotected from toxic gases and fuel. Prolonged exposure pollutes the oxygen sensor, reducing its performance.
The best way to deal with the contamination and impurities is by using oxygen sensor safe carburetor and choke cleaners. However, I would not recommend washing oxygen sensors, since I cannot guarantee if it will work once cleaned. Replacement is a better option.
Dissolves Any Deposits
As stated by most carb cleaner reviews, the most recommended cleaner is one that can dissolve any deposits. Deposits buildup in the carburetor hampers the efficient delivery of fuel. If this happens, the engine will begin to stall, be hard to start and/or run roughly.
Safe and Quickly Dissolves
For your own safety and the safety of your engine parts, I advise you to use a carburetor and choke cleaner, that is safe and quickly dissolves deposits. This may include varnish, sludge, and gum.
Support All Vehicle Engines
If you want a resourceful and versatile carburetor and choke cleaner, then you should buy a solvent that can be used or applied on any type of vehicle engine.
Wash Small and Big Engine Parts
This is in fact one of the most important features that I insist you should consider. You can avoid buying two separate carburetor and choke cleaners by buying a high-quality cleaner that is capable of cleaning small as well as large engine parts.
Chlorinated vs. Non-Chlorinated Carb Cleaner
What is Chlorinated Carburetor Cleaner?
Chlorinated carb cleaner is the more popular version, which has been in use for a long time. This is regardless of the fact that most of the ingredients used in chlorinated cleaners are banned.
A chlorinated cleaner is made up of chlorinated solvents or atoms within its molecular structure. The chemicals composed in this type of cleaner improve the solvent qualities of the product.
Due to safety and environmental considerations, chlorinated carburetor cleaners are not popular in some states. You need to consult your local authorities.
What is Non-Chlorinated Carburetor Cleaner?
A non-chlorinated cleaner; on the other hand, simply means the cleaner’s molecular structure does not contain chlorinated solvents. Nonetheless, this does not mean that non-chlorinated cleaners are environmental friendly or safe.
In some cases, the alternative compounds used in non-chlorinated cleaners are just as toxic. Unlike chlorinated solvents, non-chlorinated solvents are flammable and fast-drying.
What are the Difference between Chlorinated and Non-Chlorinated Carburetor Cleaner?
When it is time to clean deposits off your carburetor, throttle body, and choke, the two most popular choices are non-chlorinated and chlorinated cleaners. Both choices will get the job done. However, understanding key differences can avoid safety and maintenance issues.
Non-chlorinated and chlorinated cleaners do both consist of toxic chemicals. However, chlorinated cleaners consist of the more destructive elements between the two options.
Chlorinated solvents are made up of trichloroethylene, methylene chloride, and perchloroethylene. These elements are regarded as volatile organic compounds or VOC.
Non-chlorinated solvents are made of more environmental friendly compounds, including: low toxicity petroleum hydrocarbons, isopropyl alcohol, heptane, and acetone.
Which Should You Choose?
It is essential to remember that many carburetor cleaners are not compliant in all of the fifty states. Therefore, before making any purchases, you should make sure that you get the ideal model.
If you are undecided between the two types of solvents, then you should settle for Berryman (a brand that offers both choices).
On a one-on-one test, the Berryman chlorinated cleaner will produce a harder stream that will simply flash dirt off your carburetor. The Berryman non-chlorinated produces more of a mist that will take more time to clean your carburetor.
When I hold the two cans separately in my hands, I realized that the Berryman chlorinated is a lot heavier. It is more of a denser product than the Berryman non-chlorinated.
In my opinion, the non-chlorinated works fine, but you will have to use a little bit more of it for the solvent action.
When I conducted a residue test using the two Berryman products, I found out that the chlorinated does not leave residue compared to the non-chlorinated. Even though, the non-chlorinated dries faster than the chlorinated.
Based on these findings, I think you should use the non-chlorinated over the chlorinated. Regardless of the fact that chlorinated performs a little better during use.
Carb Cleaner Kit and Gloves
Having the best carburetor cleaner is not enough. You need a carb cleaner kit and gloves to successfully clean and rebuild your carburetor, throttle body, and choke. For superior organization, you should choose a kit that comes in a ring.

How to Use a Carburetor Cleaner
Remove the air cleaner unit from the engine by unscrewing the wing nut. You might need pliers to turn the wing nut if it is very tight.
Then, vacuum off the top of the engine area so as to prevent debris and dirt from being sucked into the engine while the air cleaner is not in place.
Spray the entire carb inside and outside with your carb cleaner in order to loosen vanish and gunk. You can use shop rags to effectively remove any heavy gunk and grease loosened by the solvent.
Start the engine and spray the carb cleaner down the throat of the carb as well as around the outside. Wait for a number of minutes before you switch off the engine.
Spray heavily the inside and outside of the carb once again. Start the engine again and do more spraying around the inside and outside of the carburetor.
Spray the entire air cleaner outside and inside. Wipe the air cleaner by using shop towels. Then install a new air filter element followed by the re-installation of the air cleaner unit onto the carb.
