Heavy duty engine degreaser

[zsdom]

I’m cleaning up an engine block ready for paint & a rebuild but its caked in st, really badly, steam cleaning & using brake cleaner hasnt really touched it

Any recommendations for a heavy duty cleaner to help clean it up

AG engine machine cleaner works well for me. Might take a couple of goes if it’s that bad.

Bilt hamber surfex hd is pretty good.

I like it because it rinses really well with just water.

Spray on and agitate with a brush is all it should really need.
