I’m NOT purchasing that much vinegar!
:rofl:
Though it’s probably cheaper than that solution you get at Horrible Freight. (I can’t think of the name right now of that rust converter that turns the metal black after use.)
The con rods I can see. Not the block. I’ll get some pictures later.
The best part of that black block is that it is a standard bore.
I buy the industrial strength stuff from Amazon that is 6 or 7 times the acid level of the grocery store stuff. Cut it with water in the drum. Makes some good iron fortified pickles after you do the engine soak.
