Probably a chemical reaction between the gold thread, the polisher and air. I think the sleeve stripes need to be replaced, I doubt they can be restored. Was it a parade uniform with rank stripes all around the sleeve or a service uniform with the stripes mounted in "shorter pieces"?
If it was stripe that goes all around the sleeve, I think a local army/navy supply store can sell you stripes that would look OK. It is pretty expensive though. If it is short pieces (service uniform) I have a supplier for such and you can send a PM.
