It's a principle of good engine rebuilding to wash out your block with
soap and water once it comes back from the machine shop. If they've done
anything at all to the cylinder walls they've also left a fine film of
grit that can't be easily removed with just a solvent-soaked rag.
Remember to dry the block immediately (with particular attention to the
oil channels), and then oil the whole thing down. Otherwise it will rust
in about 10 seconds.
