Handle your board by the edges only. It’s also best to avoid touching the surface as much as possible. The tray should never be filled with more than one inch of water. Don’t over saturate or fully immerse your board in water. Ensure to ONLY use a clean soft-bristled brush on the surface of the board. If water drips down the board and settles along the bottom edge, dab it with a soft cloth [especially where the board rests into the water tray].
