Heavy grease removal [India] 

July 28, 2007

We are in rebuilding of auto electrical units, and lots of old parts( heat treated carbon steel) have lots of grease in it, mostly the grease is lithium based. We generally make use of manual brushing or solvents like MC or IPA, but its very time consuming and cumbersome. Is there any way to simply dissolve the grease by just immersion or any other method, we do the shot blasting after the grease removal.
