9. Yamaha Yamalube ​- Extensive Cleaning Immersion Solvent

Editor's Rating: 4.3 out of 5 stars (4.3 / 5)

Cleaning an engine part by hand is not always the best solution. With carburetor jets, for instance, you'll get the best results from using a dip cleaner like the Yamalube cleaner from Yamaha.

You'll need to mix the formula with water and thin it down first, before use. A 50/50 solution works great and you'll need some patience as well because a full cleanup takes anywhere from two hours up to 24 hours to complete.

If you want the best carb cleaner for your car or tool engine parts, try a dip cleaner like this Yamalube because you'll not only get perfectly cleaned parts, they'll also sparkle like new.

This cleaner is not guaranteed rubber safe, so it's advisable to keep all rubber and plastic parts away from the dip solution to avoid damage.

Pros:

  • Immersion cleaner ideal for soaking carb jets
  • No need for hand cleaning
  • Includes a 30-day money back guarantee
  • Produces shiny new metal parts

How to Buy the Best Carburetor Cleaners

How to Buy the Best Carburetor Cleaner

Every product has its peculiarities, and so too, does a carb cleaner. When choosing a particular brand, you'll need to keep the following points in mind, so you can choose the best carburetor cleaner.

#1. Chlorinated vs. Non-chlorinated

Chlorine is a major substance in cleaning agents of all kinds and it helps a solvent to more easily break down dirt. You can either get a chlorinated carburetor cleaner or you can get a non-chlorinated one.

Chlorinated cleaners clean faster and more thoroughly but they are also quite abrasive. Non-chlorinated cleaners are milder but they do get the job done.

Another issue with chlorinated carb cleaners is that some jurisdictions have a ban on the sale of chlorinated cleaners. Still, a non-chlorinated cleaner might contain other chemicals that are more harmful.

#2. Eco-Friendliness

The Eco-friendliness of a carburetor cleaner is subjective and thus, something you should consider entirely on your own.

That is, if you care about the environment, then make the extra effort to only get an Eco-friendly carb cleaner. Else, this issue doesn't matter.

#3. Ease of Use

Another consideration is how easy it is to use the cleaner. Some come in spray cans, while others come in normal containers, intended for dipping the carburetor into it.

You should know how you prefer to work and which style better suits you. You should also consider if any product that you're interested in poses a safety risk in any way.

How to Clean a Carburetor (Step by Step Guide)

How to Clean a Carburetor

Once you've decided to clean your carburetor, you should take some time to consider your kind of vehicle or tool and the type of carburetor it has installed. This is because there are so many cars and carburetor designs but they all have the same basic parts.

The step by step guide below leads you through the necessary stages of cleaning a carburetor, independent of your car's or tool's make or model.

Step 1. Wear Goggles & Gloves

You should keep in mind that most carb cleaners are harmful to both skin and eyes, so it's recommended to wear goggles and gloves when using them to clean your carburetor. In case the solution does spill on you, wash it away as quickly as possible with water.

Step 2. Remove the Carburetor

Different types of engines have different types of carburetors, with tools like lawn mowers having simpler ones than cars, whose carburetors are a bit more complex.

All the same, you' may have to disconnect the carburetor from the engine first. In that case, you'll need to remove all the hoses, linkages, springs, and separate the carburetor from the engine. Feel free to take pictures along the way, so you'll remember your steps.

For most cars, you don't really need to separate the carburetor from the engine, since you can open it up in place, while still connected to the engine.

Step 3. Dismantle the Carburetor

Once the carburetor is free or can get worked on in place, you'll need to disassemble it. The length of this step depends on your carburetor's complexity. You'll need to find and open the float chamber though.

Then remove the float, including any pins, gaskets, O-rings, or other present items, depending on your engine make. It's often a great idea to take pictures before a disassembly, so you'll know how to easily assemble it back.

You'll also need to remove any rubber or plastic parts because some carb cleaners contain chemicals that'll attack and spoil them over time.

Step 6. Cleaning

Now is the time to clean your carburetor in and out. Feel free to brush the outside with a brush, but you'll have to clean the inside with a carburetor cleaner.

You can either use the spray or the dip cleaner but if you are cleaning the carburetor in place, then you can only spray. You can clean some paths with a cloth or soft brush if you're using a spray.

If you removed the carb from the engine, then you can use an immersion solution. Just leave the entire carburetor in the solution for some minutes to get a complete chemical cleansing.

Step 7. Re-Installation

Once your carburetor is clean and properly dried, then it's time to re-assemble and re-install it. This is when those pictures will come in handy, especially if you're not familiar with the carburetor assembly.

After reconnecting everything, including all wires and hoses, start your engine to make sure it works, and that's it.

Conclusion

Coming to the end of this carb cleaners review, you can see the different offers out there, with their different formulas, effectiveness, and application methods.

Whether you are looking for the best motorcycle carb cleaner or just something to clean your RV's engine with, there are plenty of offers to choose from.

It's your turn to make a choice now, and this rests on your exact needs and personal preferences. That's why this last decision is yours alone to reach.
