Our carburettor cleaning fluid has been formulated specifically for use with an ultrasonic cleaner, for cleaning carburettors, valves, fuel injectors, engine parts etc. It safely and quickly removes contaminants including general soiling and dulling, oxidisation, 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 brightens dulling that occurs over time. Obviously it can't make a component look like it did when it first left the manufacturer's factory, but results are very impressive. The cleaning process won't damage, corrode or darken metal components. Safe on brass, aluminium and other sensitive metals. It is also safe with O rings. Mix the concentrate 1 part solution to 10 parts water (25 Ltr bottle makes 250 Ltr of working solution)

The fluid can be used many times until it looks dirty. There's no specific rule about when to change the fluid, 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! 


The carburettor cleaning fluid is a concentrate and is added to water at a ratio of  10: (1 parts cleaning fluid to 10 part water). For heavily soiled components, this can be strengthened to 7:1. The working temperature of the ultrasonic cleaner should be set between 50 - 80 degrees centigrade. After cleaning rinse with clean water and leave to dry. Always test before use on new applications.
