Telefunken Concertino grill cloth
 

Well I had to do it. Radio is pristine, recapped and sounding wonderful. But the yellowed grill cloth just bugged the crap out of me. Especially once I removed it and saw what color the edges were. So I soaked it with some oxyclean and ringed out all sorts of yellow liquid (nicotine?)
After a few rinses it looked great so I hung it up to dry. Today I went to see about re-attaching it to the baffle and was shocked to see it about 2 inches shorter than it used to be. :tears:Stupid me did not realize it was cotton. So now I have to either stretch it or find a replacement.
My wife thinks if I wet it slightly I may be able to stretch it back over the baffle, but I'm not sure.
Any ideas?:scratch2:

Ouch. I'd try wetting and stretching. Maybe with a jig of some sort to apply even force. Otherwise, it may stretch unevenly.

Best bet is to clamp all the edges between slats of wood that are the same length- that way you'll almost certainly get a smooth stretch, as opposed to stretch points and a star-shaped cloth :)

There is a site which has very nice repro grill cloth. Try looking at grillecloth.com
don't forget the E after grill and before cloth
