My new (to me) BT6!

Do not use any polishes. Naptha or soap and water. If you get polish in the wood, finish will never stick to it in the future and can also start to lift the finish where it meets bare wood. Be careful.

Thanks, Ken. That' great... I'll just take gunk off with naphtha then.
Do you recommend pure lemon oil or the Howards for general fingerboard cleaning and maintenenance?
