Topband: coax soldering

[Larry]

hi guys,


planning on installing some more beverages. i have a roll of CATV 75 ohm cable. it is the kind with a double shield. aluminum wrap over tinned copper shield. there is some kind of sticky on the shield and i dont think that i can solder efficiently to it.


what is the best way to clean the "sticky" off the shield so that i can solder to it for PL259's?


thanks,
larry
