It is generally safe to clean rosewood and ebony fretboards with water. However, it is important to use a damp cloth, not a wet cloth. This will help to prevent the wood from swelling or warping. Be sure to dry the fretboard thoroughly after cleaning to prevent the wood from drying out.
Maple fretboards:
Maple fretboards are more porous than rosewood and ebony fretboards, so they are more susceptible to damage from water. It is best to avoid using water on maple fretboards. If you do need to clean a maple fretboard, use a damp cloth and dry it thoroughly immediately after cleaning.
Unfinished fretboards:
Unfinished fretboards are not sealed with a finish, so they are more susceptible to damage from water. It is best to avoid using water on unfinished fretboards. If you do need to clean an unfinished fretboard, use a very lightly dampened cloth and dry it thoroughly immediately after cleaning.
Here are some tips for cleaning your fretboard with water:
- Use a damp cloth, not a wet cloth.
- Avoid getting water in the fret slots.
- Dry the fretboard thoroughly after cleaning.
- If you have a maple fretboard, be especially careful to dry it thoroughly after cleaning.
