Default Re: Block cleaning

In my reading, muriatic acid is never a good thing for rust removal. The damage can continue long after you think it looks pretty.

I did find that electrolytic rust removal will remove the left overs from the acid in my reading.

I have found the good old wires and manual removal of the rust to be a great way to get rid of all the stuff in the block. Keep in mind not all what you find is rust. I was removing some casting sand too. Plus not all the flaky stuff, what you really need to remove, will come out with chemicals alone.
