Try TIG welding on something cleaned with brakeclean. You can see the residue burning off in the weld. Stopped using it on aluminum particularly as it really seems to penetrate
Do you mean straight ether, or the more common engine starting fluid you can buy these days which is a mixture of ether with other stuff?

Why I suggested the cheapest, you want it without the "lubricants, etc. you do have to wipe it after it dries, while it eats all the oils and stuff if will leave a powdery residue it wipes right off
