Keeping your carburetor clean is one of those things you need to consider as being important in your life. For a healthy engine, your carburetor needs to be in great condition and with product brands such as Berryman, they get the work done.

One thing we have come to learn about carburetors is that while they work great, they are in need of constant cleaning to ensure the engine is running at its peak. When deposits, sludge, gum, carbon deposits, varnish or dirt builds up, we get engine issues such as rough idling and stalling. So really, cleanliness is important.

That’s why we have listed what we have found to be the best carburetor cleaners in the market. Before we get into it, let’s see what carburetors are.

For a car to be in motion, it requires combustion to take place, where combustion is the process in which fuel burns in air. Gasoline engines need a precise amount of air for the fuel to burn perfectly. Trying to get this mixture of air and fuel at the right balance for proper burning is done by the carburetor.

Carburetors have actually been around for quite a while; since the 19th century where Karl Benz the automobile pioneer as well as Mercedes founder, developed them. However, with the introduction of throttle bodies and fuel injectors, we no longer see modern vehicles with carburetors. This doesn’t stop us from appreciating the genius behind Karl’s work.

Buyer’s Guide

When it comes to buying a cleaner for your carburetor you need to understand that it’s not just about choosing any cleaner that looks good in writing; it needs to cater to the issues in your carb. That’s why we have prepared a buyer’s guide for you so that you have a rough idea on what you’ll be looking for.

Chlorinated vs Non-Chlorinated

Whether or not a carb cleaner contains chlorine is actually a huge determining factor for most. What’s the difference you ask?

Chlorinated cleaners tend to be more thorough in cleaning and do so in no time. However, they are quite abrasive and some jurisdictions actually have a ban on their sale. So while the cleaning might be thorough, it’s quite an aggressive cleaner.

Non-chlorinated carb cleaners on the other hand are much milder but still get the job done effectively. Some non-chlorinated cleaners however have chemicals that could cause more harm so really it boils down to your decision and effect you wish to achieve on your carburetor and other parts.


This point is subjective and you get the last say. If you’re all about caring for mother earth, then you should go the extra mile in getting a product that is eco-friendly. If you could care less about mother earth constantly cares for you, then this point doesn’t really apply to you; but still, be eco-friendly; it might not hurt you but it does the environment.

Ease of Use

You need to figure out what you’re more comfortable with; do you prefer spraying or dipping? For some they find it easier to use the same pray cans while others won’t know where to start when it comes to dipping.

However, some parts may call for dipping and if you aren’t comfortable with that, then you could always take your car to your mechanic or alternatively, have the mechanic come to you. Either way you get the job done.

How effective it is

How effective the carb cleaner is is important and while buying the cheapest brand in the market might save you some cash then, it could have long term implications that will cost you more. If you to keep buying the same product over and over again and there is a better, stronger option that can get the job done in one application, then it’s time to rethink some things.

Materials used

You need to make sure you check the material used in your engine. Some carb cleaners are really strong and could end up damaging your car as they tend to be reactive with rubber and plastics.

If you’re not sure what materials have been used, then you’re better off buying a multi-fabric cleaner that is mild on the parts and will give you some peace of mind.

Cleaning the Carburetor

After choosing the right cleaner and have finally decided to clean your carb, take some time to consider the set of wheels you own and most importantly, the kind of carb it has. Different cars come with different carburetor variations although the basic parts are pretty standard.

The steps required when it comes to cleaning your carb.

Step 1. Protect yourself

As we had mentioned earlier, most carburetor cleaners are actually harmful. Areas to keep safe are your eyes as well as your skin and as such, be sure to wear gloves and goggles before starting on any cleaning process. Should any spillage happen on your skin, then you are to immediately wash it off with water.

Step 2. Removing the carburetor

Other tools such as lawn mowers have carburetors that are less complex compared to what you will find in a car.

First things first, disconnect the carburetor from the engine and then proceed to remove all the linkages, hoses, springs and now detach the carb from the engine. If you have poor memory or get easily confused, then you’re at liberty to take pictures for reassembling purposes after you are done cleaning.

Note here that you don’t necessarily need to remove the carb from the engine in most cars as you can easily open it up when it’s still connected.

Step 3. Dismantling the Carburetor

Here’s the tricky bit so stay with us.

You’ll need to remove the float bowl from the carb which you will find located at the bottom and has got four screws that hold it in place. Be careful with this part as unscrewing the wrong way can easily lead to damage.

If the float pin is being a bit stubborn and didn’t come out with the bowl, use those long-nose pliers looking things to remove it.

Observation time – no, really. Look around as well as the inside of your carburetor and familiarize yourself with the small jets; the hexagon shaped parts. These can and should come out for clean; yes, every one of them.

Other parts to be removed are air screw, idle screw, choke if it can be removed, O-rings and gaskets. In case there’s any rubber or plastic part, let it or them come off as well. With every part you open make sure you place safely and mark where they all came from.

Step 6. Cleaning

Time for a thorough cleaning. You can use a brush for the outer part of the carb but when it comes to the interior, we let our carb cleaners to do their job.

Depending on what you’re more comfortable using between the spray or dip then you can start cleaning. If the carburetor is still attached to your engine, then the choice is made for you i.e. you can only spray.

A soft cloth or soft brush can be used for cleaning of some parts. If you have everything disassembled, then why not use immersion if you have the product? It’s easier and more effective. Leave the parts dipped in the formula for a few minutes or as recommended by the instructions on your carb cleaner and shortly after have your shiny new parts ready to go.

Step 7. Re-assembling

Make sure you leave the parts to fully dry up and then re-assemble as per the picture steps you had taken; hopefully you did take some so that you’re not left with that one screw that doesn’t seem to belong anywhere.

Once everything is back where it belongs, give your engine a start to see if it still works and you’re done. Congratulations.


Do I have to detach the carburetor from the engine in order to clean it?

No, this is not a requirement. It’s the reason why so many carb cleaners come in spray cans so that you can directly spray the cleaner on your carburetor. Make sure you have rags covering the surrounding areas before you spray to avoid any runoff cleaner landing where it shouldn’t.

How often do I need to clean my carburetor?

It is advised that you clean your carburetor basically every time you have an engine oil change. On most cars, they require an oil change once they hit the 30,000 miles mark but modern cars are surpassing that mark and reaching up to 100,000 miles.

However, try and clean your carb more often instead of waiting for oil-change day. Heavy duty vehicles and cars left sitting for long periods of time will especially require more cleaning due to more deposit build-up.

Do modern cars have carburetors?

No. Carburetors are pretty old dating back to the 19th century. With modern engines, they have a throttle body and fuel injectors. The injectors are responsible for spraying the required amount of fuel.

All these three combined i.e. carburetor, throttle body and fuel injector are a part of the fuel system in a vehicle and all play a major role in fuel efficiency. Modern cars will therefore use fuel injector cleaners which goes into the gas tank, in the place of carburetor cleaners.

What are the signs of a dirty carburetor?

When it comes to your engine, the right mixture of air versus fuel is very important to the performance of your vehicle. Dirty carburetors will affect this air-fuel ratio resulting in noticeable issues such as rough idling, stalling, a decrease in horsepower among others. If you do experience some of these symptoms, clean your carburetor.


To get the most deposits removed without harming any engine part is a dream we are sure we share with a lot of you. Ours is to only hope that by giving you some of the best carburetor cleaners in the market, it will go a long way in ensuring you drive clean.
