Degreaser recommendation

[SilverShadow]

Guys need some advice....

I received my block back from the machine shop couple of months back and they had apparently chemically cleaned it.

Looking at the internal there still seems to be some carbon/oil/grease caked on.

Can anyone recommend a good spray on degreaser to clean it right up?

I was originally thinking of removing it by a wire brush bit on a air drill?

Any advice would be great!!

autoglym engine cleaner is good stuff- any halfords etc, spray on and work with a tooth brush and rinse off, although spraying it inside an engine i wouldnt know about that

I use it to clean rocker covers and air intake manifolds...they come up brand new and shiney!

Spray it on, leave it for a few minutes, spray again and agitate a bit and then wash it off.
