Eco Ultrasonic carburettor cleaner fluid gives superb cleaning performance at low temperatures. Save on heat up time and reduce energy consumption. The eco carb cleaner solution is a micro-emulsion capable of solubilising oily, hydrophobic substances in a bi-phase composition. This makes it highly effective at cleaning. Also this removes the need for chlorinated solvents, hydrocarbon solvents and high pH caustic solutions. It is very effective at a lower working temperature. Use between 15°C and 45°C for lower energy use and short heat up time. If your workshop is cold in winter, this product could be for you because it takes up to 50% less time to reach working temperature.
Eco Ultrasonic Carburettor Cleaner & Super Eco are pH neutral and environmentally friendly solutions, specially made for use in ultrasonic baths to clean at a lower temperature. Available in 2 strengths:
10:1 (standard Eco concentrate)
40:1 (super Eco concentrate)
The eco carb cleaner solution has been specially formulated to remove oil residues, grease, general dirt, carbon, aluminium oxidation etc. from engine parts. These include carburettors, fuel injectors, heat exchangers etc. Built-in corrosion inhibitors make it safe to use on all metals and it will not damage or darken components.
Working temperature of the ultrasonic bath should be between 15°C and 45°C. It works well in hard or soft water.
The eco carb cleaner is non hazardous for disposal (i.e. it can go down the drain) but please be mindful of the contamination from what you are cleaning. If the level of soiling is high please check your local disposal regulations.
The fluid can be used many times until it looks dirty. There’s no specific rule when to change it, but the idea of an ultrasonic cleaner is for deep and thorough cleaning. If your fluid looks like pea soup, it’s time to change it.

One of our customers kindly sent some photographs of his Honda CB350 / 4 carburettors before and after cleaning with an ultrasonic cleaner.
One of our customers kindly emailed some photographs of his Honda CB350/4 carburettor before and after being cleaned in an ultrasonic cleaner. The text below is from his email.
“I Just used my 6 Ltr ultrasonic bath for the first time on some old carbs. The carbs are from a 1972 Honda CB350/4 and they were all quite badly gummed up. I used the carb cleaning solution diluted as instructed (10:1) and heated the water to 65 centigrade. I cleaned them (the bike has 4) one at a time for just 20 minutes each. Please find attached 5 before and 5 after pictures of the dirtiest carburettor. Regards, Peter“. Honda CB350/4 carburettor cleaning.
The model Peter bought was a 6 Ltr ultrasonic cleaner with a simple dial adjustment for the time and temperature control. The carburettor cleaning fluid was included free.
Ultrasonic carburettor cleaning fluid in 1 Ltr and 5Ltr bottles.
Our ultrasonic carburettor cleaning fluid is perfect for cleaning carbs, valves, fuel injectors and engine parts etc. The carb cleaner safely and quickly removes contaminants including general soiling and dulling, oxidation, carbon, petrol residue and grease etc.
The fluid works very well with alloy and aluminium castings by removing physical dirt. Also it cosmetically removes the dulling that occurs over long periods of time. It won’t make a component look the same as when it was new, but results are very impressive. The cleaning process won’t damage, corrode or darken metal components. It is safe for brass, aluminium and other sensitive metals and rubber O rings.
Using the concentrated fluid
Mix the concentrated fluid 1 part solution to 10 parts water. (1 Ltr bottle will make 10 Ltr of working solution). Keep using the fluid until it looks dirty. There’s no rule about when to change it, however an ultrasonic cleaner is for deep cleaning. When the solution looks like pea soup, it’s time for a new mix.
Mix the concentrated carburettor cleaning fluid with water at a ratio of 10:1 (10 parts water to 10 parts cleaning fluid). For heavily soiled components, the ratio can be strengthened to 7:1. The working temperature on the ultrasonic cleaner should be between 50 – 80 degrees centigrade. After cleaning, rinse the parts with clean water and leave to dry.

A bikers guide how to clean a carburettor with an ultrasonic cleaner. Which size and model to buy?
ultrasonic carburettor cleaning
This is a bikers guide to buying an ultrasonic cleaner for carburettors, explaining how to select the best model for you. A grain of sand in a carburettor can stop the most powerful of motorbike engines. In the World of carburettors, cleanliness is king.
Carburettor cleaning back in the day.
I have owned motorcycles for more years than I like to admit and have rebuilt a few engines including a vintage BSA Bantam (D2), Norton Commando 750 (fastback) and a Ducati (250 Desmo). Back in the day I would soak the carburettor in a bucket of Jizer type degreasing solution for an hour or two, rinse with water and finally blow it off with an air gun. Simple, but not really very effective carb cleaning.
Ultrasonic carb cleaning today.
Technology has advanced over the last few decades. As a result when it comes to cleaning a motorbike carburettor and engine components, the best practice is with an ultrasonic cleaner. Ultrasonic cleaners have a component called a transducer. This is the part that generates ultrasonic sound waves. The sound waves produce microscopic bubbles that very effectively dislodge dirt, grime and petrol residue from the intricate parts of a carburettor that would otherwise be difficult to get to.
Which size ultrasonic cleaner?
Price is always a factor and when deciding which ultrasonic cleaner to buy, but I have a mantra about the selection process – SIZE MATTERS. I can’t say that often or loud enough, so I will repeat it, SIZE MATTERS.
Measure your carb twice, purchase once.
Several customers purchase a machine after guessing or estimating their carb will fit into a particular size ultrasonic cleaner. As a result when delivered, they discover it’s too small and want to exchange it. That isn’t a problem, but it costs the customer money to return it and it’s a bit of faffing around. The golden rule: measure twice, purchase once.
Try and get it right first time by measuring the overall dimensions of your carburettor. However this isn’t always possible especially if the carbs are still bolted to the engine. In this situation it’s a “best guesstimate”. As you will be removing some of the carb parts such as float bowls, slides, jets etc the overall size of required tank might be smaller.
If you can afford it, select an ultrasonic carburettor cleaner a bit bigger than you estimate. Trying to shoehorn a large carb into a small tank results in the cleaning being less efficient. By placing the carb into a larger tank it allows the ultrasonic waves to travel more evenly and easily. As the saying goes, “what will hold more will hold less”.

Which functions do I need?
There are three versions for most sizes of ultrasonic cleaner. In summary, the more money you pay, the greater the control over the cleaning process.
The “manual” (dial adjustment) has limited control. The “digital” range gives you full control over all aspects of the cleaning operation and importantly, you have an LED display showing the temperature of the water (it helps stop the operator plunging their hand into hot water). In addition the degassing model can give a deeper more thorough clean.
At the heart of any ultrasonic cleaner is a transducer. This is the component that produces the ultrasonic cleaning waves. The more transducers fitted to an ultrasonic bath, the better the cleaning will be. If you want to clean a bank of 4 carburettors off a motorbike but don’t want to separate them, the 22 litre digital model will be the best size for you.
The analogue adjustment ultrasonic carburettor cleaner has a simple knob / dial to set the cleaning time (0-20 minutes) and another dial for the temperature adjustment (20 – 80 degrees C). There is no LED display.
These models have a push button to set the cleaning time (0-99 minutes) and temperature (0 – 80 degrees C) with an LED display. The cleaning can be stopped mid-cycle and the temperature shows both the target temperature and actual water in the tank. In a workplace environment and working with hot water, there might be a health and safety implication that requires the tank temperature to be visible to prevent scalding to an employee.
Digital adjustment with degassing
Degassing is an addition function which after a change a cleaning solution, quickly removes air from the liquid. It makes the cleaning process more effective and is especially useful when cleaning motorbike carburettors. With some degassing models the cleaning power can be reduced by 50%. This is so that delicate products can be cleaned gently. However, for ultrasonic carb cleaning, the lower power function isn’t needed.
The cleaning fluid
Picking the correct ultrasonic cleaning fluid is as important as the machine itself. The fluids we sell are specifically formulated to work well in an ultrasonic tank. Specifically, the carburettor cleaning fluid is made to work with alloys and alloy castings. It removes petrol residue and brightens dull castings. More information (and you can also purchase) on the fluid HERE.
Using the ultrasonic carb cleaner.
Using an motorbike carb cleaner requires no special knowledge or skill. All you need is water and a specific cleaning fluid to put into the tank. The cleaner is then plugged into a domestic power socket and the built-in heater raises the temperature of the water & cleaning solution mixture to around 60 degrees centigrade (maximum 80 degrees).

Get it submerged.
After removing float bowls and jets, place your dismantled carb into the tank and turn on the ultrasonic control. Normally around 15-20 minutes is sufficient cleaning time. If the carb has not been used for many years you can leave the tank buzzing for up to 40 minutes. Leaving it in for longer will not damage it.
If parts of a carb will protrude above the water level. This isn’t a problem. Many customers simply turn the carburetor through 180 degrees and turn it on again.
After ultrasonic cleaning.
Remove the carburettor, rinse and leave it to dry. The carb will now be deep cleaned internally and externally the casting should look bright and clean. NOTE: Some alloy castings were dull when new. The ultrasonic cleaning process can’t make an old carb look better than the day it was new.
If you look through all the ultrasonic tanks we sell, the choice can be a little confusing. Below I have listed the most commonly purchased Ultrasonic Cleaners for cleaning motorbike carbs.
The 3 Ltr tanks are good for very small individual carburettors. A 6 or 9 litre tank will clean bigger individual carbs. If you need to clean a bank of 3 , 4 or 6 without splitting them, you’ll need a 22 Ltr size as a minimum.
So, you’ve now spent your money and got a shiny new ultrasonic tank. Don’t penny pinch on the cleaning fluid. It’s very important. Buy some proper carburettor cleaning fluid because an ultrasonic cleaner simply filled with plain tap water won’t remove petrol or grease. After you’ve cleaned the carb, you want it to look the part and by using cleaning solution will have the cosmetic “wow” factor. Ultrasonic cleaning fluids can be found here.
