A. Get some very fine grit sandpaper (150 will do), and gently sand off the stains. Vacuum or wipe out the sawdust with a clean cloth dampened with distilled water and/or 50/50 solution.

If you plan to place a new humidifier in the same spot, just leave the sanded area alone. This will also help give you a better bond. If not, gently wipe the area with 50/50 solution. The polyglycol in the mix will help prevent any mold from coming back. You might want to do this anyway; just make sure it’s dry before you reapply a new unit.
