ive been collecting records for way too long now and i can always remember using isopropyl alcohol (i think ive spelt that correctly) and thinking it was the bees knees and as im sat here i have a tin of the aforementioned servisol but if i can be perfectly honest the best cleaner by far is flash,yes, flash the spray on type.Simply spray on the vinyl avoiding the label as best you can and then wiping it around with a heavy cotton like t shirt material, it gets all the crap out without worrying about screwing up the vinyl,perfick!!
