The solution to pollution is dilution (read: hot soapy water and elbow grease go a long way). The headers I showed a picture of way back on 12/25 are still sitting just like they were in the box with no more rust on them now than then. I left for 3 weeks and didn't get to them. I used cold water and an acetone wipe down. But if you don't get the stuff cleaned off, it'll rust like crazy.
