Removing all trace of solder from Stainless?

[aamcle]

Evening All.

I have an old Stainless urn type vessel with the bottom soldered into place, I'd like to use it for a GrainFather type build.

I can get the bottom out using a torch to melt the solder but how do I get rid of ALL trace of the solder?

Many Thanks. Aamcle

With a torch, damp rag, and a welder's glove you can drag all but the last bit of tinning off fairly easily.

The rest you'd have to remove through abrasion if you think it's necessary. An angle grinder with a virgin 240 flap disc and a gentle touch ought to do it...

Cheers!

I'm not sure I understand why you would want to take the bottom off. Aren't you just going to have to put something back in it's place and somehow make it water tight?

That said, you can get most of it off by wiping it while it's still hot and liquid. You can get a lot of what's left with a wire wheel (be sure it's non-ferous). You'll never get it all off without grinding away a fair amount of SS but that's probably not required.
