Keeping guitars is a humid room is a plus, but not always needed for electrics. Acoustics on the other hand I would highly recommend it. I do all my own maintenance on my guitars. I change strings often due to how much I play and clean and treat the fretboard after every string change with Dr. Ducks Ax Wax. I rub down the frets and clean each one. Then rub another coat on to sit for about 20mins. After that I remove it all. It can be a lengthily process, but it keeps the fretboard smooth and hydrated. This is a must if you’re using rosewood fretboards since they can get pretty sticky. Also, during every string change I re-tune intonation and ride height (action). 2 of my guitars are Floyd Rose equip, so it’s inevitable. I’m kind of anal about how my guitars are kept, but a good rule of thumb is: Wash your hands before playing and always wipe it down when you’re done.
