GCSJ1, mold seems to be a difficult mystery to solve and I am by no means an expert, but I was seeing a wonderful doctor who specialized in mold for awhile and he showed me that I did indeed have mold in my skin. He showed me these tiny little pinhead size white dots (which of course I had never seen... I could barely see them as he pointed them out to me). He suggested I use a nizoral shampoo as a wash for my entire body. It helped.
He also told me to be sure I wasn't eating anything with mold in it (ANY tomato products that come in a can or jar as those are intentionally made from moldy tomatoes, potatoes with skins, etc... you can find a good list from mold websites). He also informed me that vitamins that say they are 'yeast free' mean that the base is developed from mold (apparently it needs to be one or the other in order to provide a base for the vitamins themselves).
There also seems to be a commonality between mold sensitivity and chemical sensitivities so you may want to cut out the Tilex altogether (I know I react to it and have to use a natural cleaner instead... Comet is even worse). I don't know if any of this is a help to you, but I thought I would toss it out there. Good luck to you!
