You don't want to spray the eggs directly too much moisture is a bad thing for mold specially, i don't and didn't spray the eggs off or clean them, i use washed play sand for my girl to dig and bury the eggs in..so i just brush off the sand and go from there, also try not to turn or roll the eggs after you have them in place in the incubation container...to do this i use a super fine felt tipped pen or marker and make little lines on the eggs, that way i know if they have been rolled or something...maybe not so much for me but i do know that mine hatched in a period of a month, if one hatched out and i didn't know and he was roaming around in there and climbing n the other eggs it could be possible to turn one and perhaps not hatch... so thats why i do it.. and I don't know if the coating on the eggs is acidic, but more like protective in a way... but i would think there is something there...

i forgot where i read it, it might have been on the forums somewhere or at this link
http://www.chameleonnews.com/year200...ncubation.html
but what it said was that as an egg exits it passes through some gland that covers the egg with the accidic coat, and if uve touched an egg after its been laid (or any time after) it feels kinda sticky (my best way of descrbing it) and what ur actually touching is that acidic membrane

if i could find it again ill post it but like i said it might have been on that link

dont ever wash your eggs , always leave them dirty , by washing them your chances of drowning the babys inside the eggs is great, and dont spray them directly either that is another good way to form mold on your eggs , it seems to me like your adding to much moisture , let the substrate be just moist, like damp to the touch but not wet and try only covering half the egg with the substrate , but its really hard to help with out being there to actually help you , so try that out
