I'm wanting to start working on my block, go ahead and do things like disassemble and notch the block. What can I do to clean it up? I'll get it hot tanked at the machine shop, but what can I do at home, like to clean up before cutting the notches and afterward to clean out all the shavings? Degreaser and the hose would do the job, but will that cause rust? What do you guys use?
