Q. My sponge looks like it has mold on it, Is there a way to clean the sponge?

A. Make sure you are using distilled water. It is not normal for the sponge to create what sounds like mold. Make sure your work area is clean. Mold can be transferred very easily via:

1. airborne mold transfer in the room or case (often times if you see dirt settling on the sponge in a mirror shape as the slats on the case holder that is a sign that your guitar is exposed to potentially dirty air transferring to the sponge.)

2. dirty hands transferring it to the sponge.

There is a successful home remedy that you can use to remove the mold spots.

You squeeze lemon juice into a spray bottle and spray on the mold then put salt in a bowl with a little warm water to make a scrub and scrub the sponge with it and then rinse well in warm water and the sponge looks like new

 

Q. My sponge is hard and will not saturate water, what do I do?
