It might sound simple to suggest how to calculate the correct amount of ultrasonic carburettor cleaning fluid to mix with water, but it’s an important aspect of the ultrasonic cleaning process and worth a few lines explaining how to get it right.
The carburettor cleaning solution is a concentrated solution and needs to be diluted (mixed) with water in a ratio of 10:1. That means for every ten parts of water, you need to add 1 part of concentrated solution. Applying that formula into the real world we need to know how many glugs of fluid to add to an ultrasonic tank and that of course will vary with the tank size.
How to mix carburettor cleaning fluid.
Let’s look at different size ultrasonic tanks and calculate how much cleaning solution to mix with water for each size of tank.
NOTE: Don’t fill the tank to the very top because when you put your carburettor in the fluid, the displacement (over spill) will run over your worktop.
3 Litre ultrasonic tank
3 litre = 3,000 ml. Mixing the fluid at 10:1 means you need 300 ml of cleaning fluid. And the easiest way to measure 300 ml is you use a normal coffee mug. A coffee mug holds 300 ml. Perfect! Add one full mug of carburettor cleaning fluid to your 3 Ltr ultrasonic cleaner and then fill the tank with water to the fill line which is about 20 mm from the top of the tank. Done. Simple as that.
6 litre ultrasonic tank
6 litre = 6,000 ml. Mixing the carburettor cleaning fluid at 10:1 ratio means that you need 600 ml of cleaning fluid. A coffee mug holds 300 ml. Add 2 x mugs of carburettor cleaning fluid to your 6 Ltr ultrasonic cleaner and then fill the tank with water up to the fill line which is about 20 mm from the top of the tank.
9 litre ultrasonic tank
9 litre = 9,000 ml. Mixing the fluid at 10:1 means that you need 900 ml of cleaning fluid. A coffee mug holds 300 ml. Add 3 x mugs of carburettor cleaning fluid to your 9 Ltr ultrasonic cleaner and then fill the tank with water up to the fill line which is about 20 mm from the top of the tank.
13 litre ultrasonic tank
13 litre = 13,000 ml. Mixing the fluid at 10:1 means that you need 1300 ml of cleaning fluid. A coffee mug holds 300 ml. Add 4.5 x mugs of carburettor cleaning fluid to your 13 Ltr ultrasonic cleaner and fill the tank with water up to the fill line which is about 20 mm from the top of the tank.
20 litre ultrasonic tank
20 litre = 20,000 ml. Mixing the fluid at 10:1 means that you need 2000 ml of cleaning fluid. A coffee mug holds 300 ml. Add 6.5 x mugs of carburettor cleaning fluid to your 20 Ltr ultrasonic cleaner and then fill the tank with water up to the fill line which is about 20 mm from the top of the tank.
Its not vital that the mix is accurate and if you have a heavily soiled carb, you might want to add an extra half a mug of cleaning fluid to a smaller ultrasonic cleaner (3 & 6 litre) and another couple of mugs full to a 20 litre machine.
And finally, the obligatory health and safety note. As much as I love the fluids that we sell, I wouldn’t want to digest it. If you intend to drink from the coffee mug used for measuring, pleas wash it first.

Carburettor cleaning fluid (5 Ltr) – FREE UK SHIPPING
Our carburettor cleaning fluid has been formulated specifically for use in an ultrasonic cleaner and works very well with carburettors, valves, fuel injectors, engine parts etc. It gives amazing results with many alloys used for engine casings such as cylinder heads, crank cases, rocker covers etc. It safely and quickly removes contaminants including general ageing, soiling and dulling, oxidation, carbon, petrol residue and grease etc. It works very well on alloys and aluminium castings, not only removing the physical dirt, but also it visually (cosmetically) brightens dulling that occurs over time. The cleaning process won't damage, corrode or darken metal components. The solution is safe on brass, aluminium and other sensitive metals. It's also safe with rubber O rings (provided that the "O" ring hasn't started to perish). Mix the concentrate 1 part solution to 10 parts water. (5 litre bottle makes 50 litre of working solution).
