What is ultrasonic cleaner degassing?

A common question regarding ultrasonic cleaners is: what is degassing?

Explained simply, degassing is the removal of microscopic air bubbles from the cleaning fluid in an ultrasonic tank. This is achieved by running the machine through a specific on / off sequence. On for 5 minutes and the off for 3 minutes etc.

Fluid gets “gassed” when a tank is filled with water. It’s like filling a bath at home. The action of water coming out of the tap draws air down into the body of the water in the bath itself. Obviously large visible bubbles surface immediately. But smaller bubbles remain suspended in the fluid. It is these microscopic bubble that need removing.

Degas fluid whenever it is changed. This quickly removes air from the liquid that in turn, makes the cleaning process more effective. This is especially useful when cleaning carburettors and anything with small holes or bores.

The great thing about degassed fluid is its increased ability to clean blind holes. The water inside a hole (cavity) in the item that you’re cleaning is just as efficient as the water outside it, thus leading to a very thorough cleaning action.

Ultrasonic cleaners with a degassing function tend to have digital controls. This also makes them a bit more expensive to buy that an analogue (dial control) model. However, with digital control comes extended cleaning times which can be useful when cleaning old carburettors.

You can see some machines with degassing functions here.

Eco carb cleaner

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.

  • Biodegradable – friendly to the environment
  • Non corrosive to metals and aluminium
  • Neutral pH
  • Can be used in hard or soft water

ultrasonic cleaning Triumph TR6 engine rocker shaft assembly

A customer who purchased a 9 litre touch screen control ultrasonic cleaner sent us “before and after” photographs shown below. They show part of a rocker shaft assembly from a 50 year old Triumph TR6 engine during a major rebuild.

The difference between before and after being placed in the ultrasonic bath is significant. The ultrasonic cleaning fluid used is formulated specifically for cleaning and alloy engine components and can safely be used on most engine parts. The running for the ultrasonic tank was around 20 minutes and the fluid was heated to 60 degrees centigrade.

Honda CB 350 / 4 ultrasonic carburettor cleaning

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“.

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.
