Running Rust

[saltysam]

I'm doing a max clean job on my old ex-USN whaleboat. It has collected a fair crop of running rust stains on some inside cockpit areas..

Some of you folks likely have experience with getting this stuff off and keeping it off.

Whats the newest and easiest scheme ?
Thanks

Ospho or Chemprime will remove the rust stains. Most good marine hardware stores handle the product. Use a cheap paint brush to "paint" it on and the rust stain will be gone faily quickly. Just flush the area with fresh water after the stain is gone.
And do not use it on your concrete drive, it will clean that also. Good luck.

Never tried Phosphoric acid to remove rust. It's used to convert iron oxide (rust) to iron phosphate(dark gray). May very well work, though. I use muriatic acid to remove rust from rusted iron/steel. They both don't seem to hurt most paint or plastics.
