Aluminum Protection

[JWebb_C7_Comp]

Hey guys and gals,

I've been doing maintenance on my A6 and my wife's Q7 and have had my local Indy do some as well. All that said, I've been reminded, after having been under each car, how cruel winter salt can be in the Chicago area. Is there anything I can/should do to keep nuts and bolts underneath the vehicles somewhat clean and free from seizure? I've read that people who store antique weapons, for example, clean and oil them for storage to prevent rust and seizure, but aluminum parts on vehicles seem as though they're constantly attacked by the elements, and it's unclear if there's anything worthwhile I can do... Please advise if you have thoughts. Thank you!

The simplest and quickest way is just spraying it with water. Salt is soluble, water easily removes it. The aluminium oxidizes nearly instantly once clean, stopping further corrosion. I have one of those rolling underbody pressure washer attachments, and that easily rinses off any salty residue.

If that is not an option, you can use CRC 6026 corrosion inhibitor spray before the winter season. It's not permanent, but it can protect for quite a while, and gains longevity if you can rinse off the salt whenever you can.
