This Gunk carb cleaner is pretty much a chlorinated version of the other Gunk cleaner mentioned in this list. This means this spray carburetor cleaner is likely to be more powerful than its aforementioned sibling. Even though this is a better carb cleaner because of this power, the user has to be more careful with its application since this is not as easy on other materials as its non-chlorinated version. Still, because of its powerful formula and proven track record, it sits quite high on our list.

  • Great for cleaning specifics parts
  • Shouldn’t be used near rubber or plastic

  • Model M4814
  • Weight 1.1 pounds

This is an easy-to-use cleaner that is designed to be used with the carb still in the car, which is why it includes a straw that aids in the directional spray application of the product.

It is important to mention that this product is extremely flammable, so be extra careful when using it.

Key Features

Gunk is one of the most popular brands in this field. This particular offering’s best attribute is the lack of chlorination, which makes for a much more engine-friendly spray that can be used across the various parts. The lack of chlorination does make it a little less efficient than other offerings in this segment, but for places where chlorinated carb cleaners are banned, this is almost as good as it gets.

Key Features
  • Non-chlorinated
  • Highly reviewed
  • Low VOC solvents
  • Brand Gunk

Designed to address the carburetor specifically, the formula loosens and helps remove any deposits present in the system.

It’s worth noting that, while the container is solid, the cap leaves something to be desired. It’s easy to chip and damage the seal, so be careful when handling the container.

Keep it on your regular maintenance schedule for every three months in order to see optimal results.

Best Carburetor Cleaner Buying Guide & FAQ

What to Consider When Buying a Carburetor Cleaner

Ease of Use

The most effective cleaner for you will be one that you can use quickly and safely, then get on with your day. Otherwise, you might as well head to a local mechanic.


As with all things, a cheaper brand may save you money in the short-term, but the costs can add up quickly if you have to keep buying it to do the same job a more expensive brand can do first time.

Best Carb Cleaner for Your Needs

You may not need to take apart your carburetor completely. If you have a newer car, it can be worth just grabbing a carb-cleaning spray that does the trick. Of course, an older car will probably need a full carburetor dip, which would involve taking each piece apart and leaving them to soak overnight.

Materials Used

If your carburetor or nearby equipment has rubber or plastic areas, some carb cleaners may be too strong and, ultimately, cause more damage to your car.


Some cleaners can take a few minutes, whereas others will require you to take your vehicle off the road and perhaps remove the carburetor completely. You’ll usually see this in more of the deep-cleaning carb cleaner types, but they can appear in any form. Be sure to read the instructions before purchasing your product.


Carb cleaner is a corrosive solvent. In fact, many ingredients found in common carb and parts cleaners are illegal to use in some states (California, we’re looking at you.) Check the ingredients, and be sure to get the right cleaner for your needs and location.

Benefits of Cleaning Your Carburetor

Improved Fuel Efficiency

Years of built-up dirt and grime like grease, oil, and sludge can starve your engine of fuel, which ultimately limits its combustion and therefore, your car’s performance. Carb cleaner removes deposits, helps improve engine performance, and delivers better fuel economy.

Better Acceleration

When gas from your fuel system struggles to get to your engine, your acceleration can suffer. Using a cleaner removes the gunk, giving you more responsive and immediate acceleration.

Achieve a More Precise Air/Fuel Ratio

If fuel isn’t getting where it needs to go, you can wind up with a less-than-ideal air/fuel ratio, which results in bad performance and worse fuel economy. With a carb cleaner, you can eliminate these woes—and potential problems.

Prevent Engine Failure and Other Issues

No car owner wants to replace their engine. You can avoid this frustrating and costly problem by using a carburetor cleaner that will remove deposits that can, over time, lead to expensive repairs.

Types of Carburetor Cleaners


Chlorinated carb cleaners are quite common—and that’s because chlorine is a highly effective cleaning agent. It can break down dirt easily, acting as a cleaner quickly and reducing the amount of effort or time you need to expend. However, chlorinated carb cleaners can damage more delicate components or materials. Especially potent and able to clean thoroughly, a chlorinated product can be a good choice.


An alternative to chlorinated cleaners is non-chlorinated carb cleaners. These cleaning products are gentler, as they don’t include any harsh chlorine, and usually available in all 50 states. However, a non-chlorinated solution is milder. It’ll be perfectly safe to use on all surfaces, but it may pose a challenge if you’re dealing with particularly tough dirt, grime, or deposits.


Spray carb cleaners are incredibly straightforward and easy to use, and they’re mainly for light, quick exterior cleaning. They remove dirt, grime, and other stuck-on materials with the press of a button—spray cleaners typically come in aerosol forms with a thin straw that allows you to spray the solution into hard-to-reach areas. They’re convenient, and they don’t require you to remove your carburetor. 


Dips are a deeper cleaner. These cleaning formulas can get your carburetor and choke valves sparking clean, but you’ll have to immerse your carburetor into the cleaner. It’s like giving your carb a bath. You’ll remove it from your vehicle and place it in a container filled with dip cleaner, then let it soak to get completely clean. These products are very effective, but they do require more time and effort.

Carburetor Cleaner FAQs

Q: How does carburetor cleaner work?

Carb cleaner works by dissolving the oil, grease, and other dirt and grime can that build up both on and inside your carburetor. 

Q: How many types of carb cleaners are there?

Carb cleaners can be simply classified by two main characteristics: ingredients and type of  application. Carb cleaners are also chlorinated or non-chlorinated. Chlorine is a highly effective cleaning agent, but many states (like California) have banned the use and sale of chlorinated carb cleaners. Non-chlorinated carb cleaner is gentler on most surfaces, but may pose a challenge if you’re dealing with particularly tough dirt, grime, or deposits. It’s also important to note that non-chlorinated carb cleaners can be just as, or even more, toxic than chlorinated carb cleaners.
Carburetor Components

Q: Are carb cleaners safe?

Carb cleaners are definitely not safe for human consumption. They can irritate eyes and skin, and breathing the fumes for long periods of time is not healthy.  Carb cleaner is also extremely flammable. Chlorinated formulas are okay on plastic but both chlorinated and non-chlorinated carb cleaners can damage painted and finished surfaces. 

Q: How often should I clean my carburetor?

The timeline depends on how often and how you use your car but it is recommended to clean your carburetor once a year.

Q: Can I clean my carburetor using WD-40?

WD-40 can work as a carb cleaner in a pinch. However, it doesn’t work as easily or as effectively as a true carburetor cleaner; you’ll need to work harder to get rid of really stubborn dirt and grime inside and out.

Our Top Pick

Our top pick is the Berryman Chem-Dip Carburetor and Parts Cleaner, which boasts a strong non-chlorinated formula to get the job done. The powerful formula yields excellent results.
