Reusing old hangers

Hey,

I've started rebolting an area where most bolts were 3/8 galvanized steel used in conjunction with Metolius Stainless steel hangers. Now these were installed over 15-20 years ago. Naturally, because of the mixing of metal, the bolts have rusted up pretty bad and the hangers are still in good shape. They just have a little surface rust on them
So I kept the old hangers and dipped them in CLR (rust and deposit remover) and now they look brand new!!
Could I reuse these? I may seem like a cheap bastard if I do this but I mean if the hangers are still in good shape, why bother replacing them? Ultimately, it will just mean more trash in the landfill. This being said, I wouldn't want to jeopardize the safety of the hanger. So if anyone knows more about this please come forward.

i will take them if you don't want to use them.

I'd climb on them...

I'd bet they're ok...

I'll fight Darren for the disposal rights...

Thanks, Looks like I'll reuse them.
To the guys who want them, if ever you guys come climbing here in New Brunswick, I'll give you some hehe.
