What to Look for Before Getting a Motorcycle Carb Cleaner?

There are somethings that you must consider before buying a proper carburetor cleaner.

If you buy a product without any consideration, then there is a high possibility that you will end up having a hard time with it.

These crucial things of concern may have significant results while you are cleaning the carburetor of your motorbike.


This aspect is something that you should not take lightly. Safety is an essential element in human life. Some products in the market may cause various reactions to different types of people. So, before purchasing an item, check if you are allergic to any ingredients used in it.

Moreover, some of the cleaners may be corrosive or dangerous. Please avoid them, as they are only for professional use. They may have a fatal reaction to your body. So, be super sure and check if the product is safe for you or not.

Ingredients Used 

Not all the cleaners are suitable for every type of carburetor. There may be some plastic or rubber areas near your carburetor. If that is the case, then you will not be able to use highly corrosive cleaners.

It will end up melting those parts, which will ultimately damage your vehicle more than it cleans. On the other hand, products that are not highly corrosive may sometimes prove to be ineffective for certain types of engines.

First, you must check what sort of carburetor your vehicle uses. If you still feel insecure, then the best option is to purchase a multi-fabric cleaner. It will not harm your car and at the same time, will complete the job decently.

Easy to Implement 

One crucial aspect that you must consider before buying a product is its ease of use. If it is not effortless to use it, then why bother getting it in the first place? It will not matter if the item is the best in the world if you cannot get the job done seamlessly.

If that happens, then first of all, you will lose a lot of precious time. Moreover, it will be counterproductive for you. So, we strongly suggest that you buy an item that is easy to implement.

The Speediness of the Carb Cleaner

Generally, some products can do the job quickly, whereas others take up a significant amount of time. The fast ones are useful when you are running on schedule. It will only take a few minutes, and the next thing you know, you are on the road with your vehicle.

However, if you want a deep cleaning of your carburetor, then you should use the one that works overnight. The process is indeed time-consuming; however, the results are extraordinary. You will have squeaky clean carb when the parts soak properly.

Effectiveness of the Cleaner

Now, this is something we believe is very significant before getting a product. Put yourself in a hypothetical situation where you have bought a cheap cleanser. An inexpensive item is not costly because it lacks some crucial aspects.

In that case, you will see that you are in the market all the time buying a new carb cleaner now and then. This thing will eventually end up costing you more, which you could have avoided if only you chose a slightly expensive product.

So, it is better to buy an item that is effective even if it is a little costly. In the end, you will notice that it saved a lot of your precious balance.

Nonetheless, there are some products on the market that are inexpensive and effective. Therefore, without proper research, you should never get yourself a carb cleaner.


You have noticed that we have discussed the simple things of consideration before getting a carburetor cleanser. Now, let us dive a little deeper and witness some complicated elements such as High Energy Solvent Technology.

HEST improves the drivability and fuel efficiency of your vehicle. Primarily, the technology was introduced to clean the whole carburetor efficiently without leaving a single spot. It means that the product will leave no place unpolished starting from the gas tank to the combustion compartment.

If you drive a motorbike regularly, you will notice that a dirty fuel system can result in rough idling, hard starting, no fuel economy, and numerous engine issues. Thus, it is best to buy an item that includes HEST.

Nevertheless, if you read the label carefully, you will notice if the product is formulated with this technology or not.

Types of Carb Cleaners   

If we talk about the different categories of engine cleansers, then the two most common types are the chlorinated and the non-chlorinated ones. Both of the products can help you with your cleansing process. However, if you dig a little deep, then you will see there is a fine line between them.

The chlorinated ones contain corrosive materials that are useful for a deep wash. They are of perchloroethylene, methylene chloride, and trichloroethylene. These are all volatile ingredients that are harmful to the human body and environment. However, nothing cleanses a rusty engine better than a chlorinated carb cleaner.

On the other hand, non-chlorinated liquids are environment-friendly, and they only use low toxicity materials. Most of the non-chlorinated solvents are made up of heptane, isopropyl alcohol, and petroleum hydrocarbons.

The only backfire to these kinds of chemicals is their ineffectiveness of cleaning a rusty engine. So before getting a carb cleaner, check which of them suits best to your interest.

Included Accessories 

If you are experienced with the cleansing process of a motorcycle carburetor, then you must know that you require some additional items for your work.

A pair of gloves and a carb washer kit is very crucial for a total cleansing. So, one way or the other, you will need them. Therefore, it is better to buy one that comes with all the necessary items for you to start your work immediately.

It is vital to look through all these aspects if you want to buy the best motorcycle carb cleaner additive on the market.

Frequently Asked Questions

1. What is a carb cleaner? 

This is the most common question that people often ask. A carburetor or engine cleanser can come as liquid solvents or as sprays. However, the important thing is that they are created to wash your engine system.

The ingredients or materials in such a product can melt gunk, gum, paint, or other deposits assembled in various parts of the engine. When you combine the solvent with diesel or gasoline, it becomes much more effective.

One other thing, you need to keep in mind that not all the engines are compatible with all types of carb cleaners. If you are confused about this fact, then you must consider taking the help of a professional mechanic.

2. How do I use a Carb Cleaner? 

The first thing you need to do is to detach the air cleaner from the engine. Then you have to use a blower or a vacuum cleaner to remove all the debris or dust from the carburetor.

You must complete this step carefully as debris or dirt can enter your engine with the help of the liquid solvents.

Once you are done with vacuuming, you can use the spray to wash your engine. On the other hand, if you are using liquid carb cleaner, then the first thing you need to do is to remove the carburetor from the vehicle.

After doing that, dump the engine into the solvent and dry until it is usable. The former method takes more time than the first one. So, choose wisely.

3. How many times do I need to clean my carburetor?

Usually, mechanics suggest that you must use a fuel injection whenever you need to fill up the tank of your vehicle.

Furthermore, you have to use a spray cleaner once every month. They also recommend that the optimal time for using a carburetor cleaner dip is three months.

However, it is not essential to follow all these rules exactly as they are. There are some aspects that may come into play, such as the age of your vehicle, how many miles it has gone through, etc.

If your car is old and rusty, then it may need more oiling than newer vehicles. On the other hand, new vehicles require less maintaining.

4. Does a carb cleaner work? 

Yes, of course, it works. It will make the engine of your vehicle squeaky clean. However, only washing your carb does not mean that you are maintaining it. There are a lot of things that you must consider while taking care of a carburetor.
