Ultrasonic Cleaner	Cleaning Agent	Temperature(s)	Concentration
Kemet MI80 Ultrasonic Cleaner	Rodastel 30	60°C	10%
Kemet MI80 Ultrasonic Cleaner	Deionised Water	40°C	100%

Process for cleaning aluminium Carburetors:

Each part was individually processed in the ultrasonic wash tank using Roadastel 30 (Which is a low acidic, not classed as hazardous). After a cycle of 10 minutes the part is removed and placed into the rinse tank to neutralise. All parts where dried manually.

Cleaning Carb Housing - Case Study

Customers Criteria: To remove fuel residue and corrosion. To brighten the base metal.
Component: Carb housing
Material: Aluminium
Contamination prior to cleaning: Fuel residue, corrosion, general dirt
Total number off: 1
Number off per run: 1

Ultrasonic Cleaner	Cleaning Agent	Temperature(s)	Concentration
Kemet 12 Ultrasonic Cleaner	Galvex 18:01	50°C	5%
Kemet MI 40 Rinse Tank	Deionised water/1%ACA	50°C	99%

Process for cleaning carb housing:

The carb housing was placed into the Kemet 12 and had a cycle of 20 minutes. Immediately after, was removed and placed into the MI 40 rinse tank manually dunked several times to ensure a through clean. The carb was manually dried with an air supply. This process was repeated for each cleaning fluid.

% Satisfactorily Cleaned: 80%.
Etched effect: None

Results: The Galvex 18:01 had removed all contamination, however, some corrosion is still visible and would need an additional clean with the Rodastel 30 fluid (see above case study for concentration and temperature).
