Been doing some work for a customer, some of you may have seen the m30 cylinder head rebuild in the m30 section. The customer asked for some blast cleaning to be done on the engine aluminium parts. Sadly no before shots on these.


The media used was soda, to remove all the caked in cr4p/oil/gunk, followed by a go over with glass beads, which is what gives it the nice sheen.
Heres the hot bodies as promised
Before


And after




This was just done using soda only, it has a gentle action against aluminium and does not damage it, yet does a great job of removing the ingrained oil, and film. It is soluble so can be washed off and will not damage bearings or machined surfaces.
