Dirty Pistons - How to clean?

[dgiles79]

I'm replacing my head gaskets, LIM gaskets etc and my pistons look really dirty. What's the best way to clean them up without causing any damage?

I'm no expert, so this may be normal, but I have attached pics of the cylinders.

Thanks.

Spray them off with brake cleaner and make sure to wipe everything up with a rag.
