AHH!!! MOLD!!! What do I do?

Take a paper towel or soft cotton cloth.

Gently clean all the mold off.

Get a new paper towel or a new cotton cloth repeat the process.

I usually do three iterations of this to make sure I have gotten as many of the mold spores as humanly possible. I even blow my sticks off after with compressed air (if you do this be careful)

In my three instances of mold, never has it come back.

You need to clean whatever they where in as well, bet thing is de natured alcohol.

If the mold isn't in the sticks (like the foot) you are ok and they should be fine to smoke from my experience.
