How do you clean a galvanized trailer?

[jonnyspeed]

Just purchased a 1990 Checkmate Pulse 186 with a 1990 Harding galvanized trailer. I'm trying to figure out what I can do to spruce it up. I'm thinking about powerwashing, but I'm open to any other suggestions as I've never owned a galvanized trailer before...

Vinagar will take out and stains on it just put it in a spray bottle and spray it on scrub it do scrub it and rinse

Straight vinegar all over, then a good powerwashing.

Stronger acids will fizzle and turn it dark gray.

Was it on the bottom of a lake or something??

They look like hell when they're new. That's the way they are. They don't dissolve in salt water though.
