- The Verdict
Features to Consider in Good Carburetor and Throttle Body Cleaners
Carburetors require strong solvents to dissolve grime in the bores. It has to be a fluid which quickly evaporates or dissolves in the gasoline when you start the engine. On the other hand, you have to use a fluid that will clean the residues on a throttle body. The carburetor and throttle body cleaners contain acetone which are solvents for hydrocarbon.
While carburetor cleaners tend to be more aggressive and evaporate quickly, the throttle body cleaners are less aggressive and slow to evaporate. You can use a carburetor cleaner on a throttle body, but it will mean that you have to use more of it and several times to prevent carbon buildup. Consider the following points when choosing the best carburetor and throttle body cleaners.
Purpose
You have to consider what you intend the carburetor cleaner to remove. Most cleaners will remove several substances such as gum, varnish, and carbon deposits. These deposits stick to your carburetor and throttle body to affect the fuel injection system. Therefore, before you choose the carburetor and throttle body cleaner, you should check its function.
Friendly to engine parts
When choosing a carburetor and throttle body cleaner, make sure that it cannot affect some engine parts including the oxygen sensors. Most of the formulations can be used on the majority of engines and fuel system parts. But, it’s a great concern to people who have newer car models.
Effectiveness
The purpose of using carburetor and throttle body cleaners is to improve the performance of your engine. The carburetor and throttle cleaner have to prevent the engine’s emissions and improve its horsepower. Hence, it’s important to choose the best cleaner that has the right formulation that will improve the performance of your engine.
Ease of use
Carburetor and throttle cleaners come in 2 different forms which are sprays and fuel additives. Using a spray isn’t easy because you will have to access the carburetor directly but it depends on the type of car. It involves taking out an air filter and unhooking some hoses. Carburetor and throttle cleaner formulas which come additives are easier to use because you just need to add them in the gas tank. Importantly, the cleaner must be quick to dry up on your carburetor so that you can use the car right away.

20. STA-BIL 360° Performance with Vapor Technology
Editor’s Rating:
Design Features
With a distinct formulation, the diesel fuel additive is one of the most interesting solutions for drivers to consider. It comes in a practical bottle which can be used as often as needed to pour the additive directly in the fuel tank.
Even more, it is highly recommended for its medium-size 946ml bottle which can be stored in the trunk easily. Compared to many other larger diesel fuel additive containers, it doesn’t need to be separated in multiple bottles. Even more, 4 ounce 8-packs are also available.
Convenient Features
One of the distinct characteristics of the additive is that it works with a vapor formulation. So while it benefits the areas below the fuel line, it also benefits areas above this line. As a result, it is one of the best solutions to help prevent corrosion.
Of course, preventing corrosion should be a priority for new and old vehicles. But some of the older cars on the road may benefit from this formulation a bit more. The fuel additive helps remove water and this is why it can be one of the formulas to help keep corrosion away.
Another benefit of the diesel fuel additive is the fact that it helps clean the engine. These products are often seen as cleansers as a group and this is why they can help maintain diesel engines in better shape. At the same time, it can even prevent ethanol fuel-related damage to the diesel engine, offering a premium fuel even mixed with non-additive formulas.
Another benefit to having stable diesel is with diesel storage. For this purpose, it is important to note that some drivers might even consider storing pre-mixed diesel fuel at home. This way, they would not need to carry the diesel fuel additive in the vehicle.
Verdict
With a distinct vapor formula, the diesel fuel additive scores highly for corrosion prevention and ethanol damage.
Pros
- Prevents engine corrosion
- Fights ethanol fuel-related damage
- Stabilizes diesel for storage
- Cleans the fuel system
Cons
- Mainly valuable in the 32ounce version

Guide to Buying the Best Carburetor and Throttle Body Cleaners
The above 30 carburetor and throttle body cleaners are the best that you can find on the market. They come as sprays and fuel additives, so be sure you know what you are doing before purchasing them. Most of these cleaners are easy to use and make sure that you get the solvents in all the vents and openings to ensure maximum performance for the engine. Here is what to look for before buying the best carburetor and throttle body cleaners.
What to Look for When purchasing carburetor and throttle body cleaners
There are various types of the carburetor and throttle body cleaners and most of them have multiple uses. Some sprays perform different functions such as cleaning spark plugs or cleaning oil stains in your engine. Because of this, you will find out that you are cleaning the deposits in the carburetor and throttle body while also removing the oil stains. If you are looking to purchase such kind of a cleaner, then you need to look at all the things that it can do.
Fuel additives are quite easier to use than the sprays because you just have to open the gas tank and pour in the cleaner. Once the cleaner is inside, it will clean the carburetor while the engine is running. The only problem is that this method is not as effective as the sprays which are poured right inside the carburetor. It’s more of keeping the engine in perfect condition rather than removing the deposits.
It’s a great idea to check if the cleaner has the right formula to use on your carburetor and throttle body. Some cleaners are not safe to use on oxygen sensors and catalytic converters because they can damage them. Make sure that you should use only the cleaners that will not cause more problems for the engine. Importantly, ensure that the cleaner complies with the Volatile organic compounds (VOC) standards because of the requirements by the California Air Resources Board (CARB).
The Verdict
The best carburetor and throttle body cleaner should ensure that your engine is restored to its original condition. It improves the performance of the engine, making it use less fuel. The type of cleaner that you decide to purchase is entirely up to you. But the best one should be able to eliminate deposits such as varnish, carbon, gum, and fuel residues that stick up on your throttle body.
