Hello. First time poster as I recently purchased a used Epiphone Goth Thunderbird IV for $140. I never held one as I’m told you should first, but at that price, I could not pass it by. It’s really dirty with dust and I’m wondering the best way to clean the entire bass. I read the rosewood fretboard is best cleaned with lemon oil. What about the mahogany body? Until I can replace the strings, I’m going with a soft damp cloth. I’m debating to place flatwound strings on the bass. Any thoughts would be appreciated. Thanks
