Process for cleaning radiator internal part:

Decospray HT13 was used due to its very high degreasing and oil separation properties. An off cut of a radiator was tested in a smaller bench top ultrasonic for testing. The tank was degassed and allowed to reach temperature before cleaning. The samples was placed in the basket and submerged in the tank and set for a cycle time of 10 minutes.

A quick inspection shows the cleaning agent is effective at removing the contamination and is not attacking the sensitive metals, heavy contamination is still remaining and further cleaning is required. The sample had a total cleaning time of 2 hours in the ultrasonic before being rinsed in tap water for 3 minutes and finally dried in a hot air dryer for 15 minutes at 65°C

Notes: Decospray HT13 is a stronger alkaline cleaning detergent with a PH value of 14; this stronger cleaning detergent proves more effective at removing the contamination in a shorter cycle time without attacking the sensitive metals.
