I wiped some fastfret type stuff on my acoustics fingerboard/strings last night, as they havent been cleaned for ages. Today I go to play it and notice the fingerboard has loads of white bits appeared from no where, I guess the grain has reacted to the stuff? It doesnt affect its playability or anything as it still feels all smooth, but it doesnt look very nice! Its a rosewood fingerboard I think. Should I let some lemon oil soak in next time I change strings? (also, itd be a good thing if someone could give me a how-to on changing acoustic strings as I've never done it before, its one of those bridges with the push in pin bits)
Cheers!
