If it were me I'd definitely want to at least try
to resurrect them.
Others (with more money than me
) will no doubt say throw them away and buy new ones.
Here's what I'd probably do:
1. Give them a thorough rub with a Scotchbrite pad.
2. Wipe them thoroughly with a Bass Brites
3. Boil them in water for 5 minutes.
4. Pull them out of the boiling water hot and let them air dry for 10 mins.
5. Give them a rub with a GHS Fast Fret pad.
6. Fit them to a bass and play away!
