Engine surface corrosion

[LuvDaBlues]

1-2 months ago the east side of Dallas was engulfed with, for lack of better words, a humidity storm. Everything in the garage was covered with mist and dripping. The floor slab was slippery as snot. Within days, anything steel not covered or enclosed that misty day had a bit of rust or small corrosion. Tools, car parts, metal boxes, etc..

Inside the cars engine bay, the new aluminum intake, linkage on the carburetor and the canton oil pan are now spotted with white surface corrosion. Most of the exposed bolt heads now have a light layer of red rust. I keep a cover on my car in the garage just to keep the dust out. But it looks as if it may have trapped the moister inside the bay. My family thinks the moister may have come up from the Gulf of Mexico....... i.e. salty.

Anyone recommend anything to clean this crap off? Tricks of the trade?

Thanks
