Hey all. I'm an NJ resident, and due to Sandy my entire razor collection recently got submerged in salt water.

I'm a Henckels man primarily, and surprisingly my 7/8 scalloped back Friodur came out completely unscathed. I cannot say the same for the rest of them, bunch of 50's, a couple 401s, and some other assorted non-Henckels blades.

All I've done so far is hose the lot of them down with WD-40 to displace the water and stop the rust on them from getting any worse. I have some time this weekend though, so I was hoping for a little advice on my approach here.

First question, my brother gave me a can of "Rubachem Loosey Goosey", which he claims will make the rust "fall right off". I'm currently testing this out on a blade I have that never honed right so I'm not worried about losing it. Anyway, does anyone know anything about this stuff, would I be putting myself at risk shaving with a blade that's been treated with it?

Second question, I've had some luck in the past removing surface rust and patina from blades that I've picked up using Maas metal polish and a Dremel with a buffing wheel, but I've never had to remove so much before and I know that the process leaves me with less steel to work with. I've never fully understood what patina is though, so I was wondering if leaving some behind is a bad thing, i.e. will it continue to spread and weaken the steel?

Any other tips or advice would be greatly appreciated, sorry for the long post and sob story.
