I went to the junkyard today looking for EDC and found 3 of them. All I believe were 210's. One had FORD stamped on the tag, another had motorsports, and the one I got had York on it. The 2 I didnt get were in Ford F100's and the one I got was in a Volvo. I was wondering what is the best way to clean this thing up without messing it up? I tried a pressure washer but that didnt work. I have access to a solvent tank at work? I know I have to cap off the ports at the top but is there anything else I should worry about?
