So I checked my humidor a couple weeks ago, and the humidifier inside was fuzzy- it had some mold or something growing on it that was white and fuzzy! This of course was quite concerning, since I didn’t want the cigars, of which I had quite a few nice ones in there, to get messed up.
So being the frugal person I am, I figured I would try to clean up the humidifier and see if I could re-use it. So I took it apart, cleaned the plastic case with bleach, and tried scraping off the fuzzy stuff as best I could from the green block inside. Needless to say, this didn’t actually work. I went out of town a couple weeks, and when I got back, the humidifier was fuzzy again, maybe even worse than the first time. So I pulled the humidifier out of the humidor.
First step- check my local shop for a new humidifier. Even at a store with great prices like Top Hat Tobacco, a replacement was around $30. Ouch. So I think “Why not replace the green stuff inside the humidifier with some new green stuff? It looks just like the stuff you get from a craft store for sticking flowers into.”
So here I am at work, cutting out a new block of green humidor foam. I will let you know how it worked in a week or two. If any of you out there need some, I have plenty to spare- just stop by the shop and cut a piece off for yourself. ![]()

So how is the new green stuff and the humidity doing? Also i may come and get some from ya if you dont mind. My humidor is not staying consistent and before i purchase another humidifer i want to know if its my humidor or the humidifier.
It is now middle of February and the new green stuff is doing fine! No hints of fuzzy stuff growing in there anymore! Oh, and I did have someone stop by here and I must have misplaced that extra green stuff I had, so sorry Craig if you are the guy who stopped by and I couldn’t find it for you!! I am currently reorganizing my basement and might have put it down there, so hopefully I can find it and bring it on in to the shop…. -Eric
So I remembered this post, and figured I’d let you all know that it is now the beginning of September and there’s still no mold or fuzzy stuff growing on the reworked humidifier! Working like a champ!
Also a note: make sure you buy the kind of green foam that is designed to hold water. There’s also another type that does not hold water and of course it won’t work. I found that out the hard way on someone else’s humidor!
