i can't see ice damaging vinyl, it's only water and i've washed some of my records before. i think maybe freezing the record, then the chuddy should just pop right off, but you might have to give the area a good clean after
ouch! so not only has he fucked up one of your tunes he's also mashed up one of your needles, what a cunt!!
Also, i'd check this before trying as I'm not really basing this on any concrete knowledge, but i think vinyl cleaning fluid might help get it off if your careful how you do it. The stuff I got smells like its made with that methylated spirit stuff and I swear I remember hearing you can get rid of chewing gum with that stuff somewhere. But seriously ask some other people bout that if your gonna try it I don't wanna be responsible for doing even more damage to your tune lol!
i got mates like that, it pisses me off cos they dont understand that its like me going into their room and pissing on the bed! ithink ice is probably your best bet mate, worst that can happen is it wont work, water doesnt do damage to vinyl
