question about mold

[Rusty Eads]

I have 3 sheets of mdf that are stored in my wood room. I went to grab a piece to make some drawer bottoms and noticed that the bottom had gotten a little damp from sitting on the concrete. What worries me is the green and yellow fuzz growing up from there. Will spraying the sheets down with lysol or other mold killer keep it from spreading making these sheets salvagable or should I just find a way to get rid of all three sheets? Also, is the rest of my wood in jeopardy of growing mold from this? The rest of my wood (oak, cherry, walnut, ash) is not sitting on the concrete and is all stickered.

Mold requires water. Keep your wood dry and it won't mold.

On the MDF, you'll probably find that the sheet is thicker where it has been wet. MDF does that. Throw the damaged part away. The remainder should be usable.

Cut out the parts that show direct damage.
Keep the rest dry and any mold will die and the mdf/wood will be usable.
