Black spots on hartflet beads. HELP!!#

[Rmufb71]

I have used destilled.... but I was dunking them in the cheese cloth sack and shaking it out. and then putting it in a small tupaware container and last time I did it they where still pretty saturated... Sounds like I am messing up everywhere. Appreciate the help!


Also i am doing an expirment with a spare and empty tupador and the old beads. Cooked them at 350 for an hour to kill the mold and put them in there to see in a similar set up but not as wet to see if it regrows. I am interested to see if they can be salvaged... if they can't no biggie more are already on the way.
