my bass string are realy grubby, its a cheapo 5 string bass with 3 types of bass strings on, the B sting nas been on since i got it (about 2 or 3 years ago) so as you can gess its as grubby as hell. im not going to buy new strings becouse they cost to much and im saving for a Rickenbacker. my problem is this, my stings are so bad they have gone greyish and are lifeless and dull. is there anyway i can clean them up and/or make them sound better? without having to go to the shops or without buying anything. i had a look for some rubbing alcohol and i cant find any. any other ideas? i read somewhere about boiling them? will vodka work?
