i have a few fender basses, all later models (later than 2000) and they are all completely gloss covered. i know there is 'guitar/bass cleaner' but is it really worth it? i mean, they're all covered in poly (no highway ones here) and it's fairly thick from my understanding. so is it really going to make a difference if i wipe my bass down with something not specifically meant for that? if no why and if yes what do you use. thanks guys.
