Tokay Gecko climbing issue.

Question
Okay, so I've been dealing with geckos and other reptiles for a while(I've had Leopards, Fat-Tails, Cresteds, Day Geckos, and Panther Geckos, a pair of Jacksons Chameleons, Beardies, and a few different kinds of snake) So there is quite a bit that I know about them, but there is a new issue that hasn't happened to me before.  I recently got a Juvie Tokay Gecko, and she has been having some problems with her foot pads.  She doesn't seem to be able to climb the glass of her terrarium.  After a shed she is able to for a couple days, but then she starts to slide off.  I can't figure out what the problem is.

Here is her terrarium information.  Can you please let me know is something is wrong with the setup or is this happening for another reason.

-----------------------

It is a Zoo-Med 18x18x24 Naturalistic Terrarium.
---
The Substrate is a Mixture of Fir chips, and Sphagnum Peat Moss.
The plants are all artificial except for frog moss for moisture.
---
It is heated with a 75 watt Day bulb for 8 hours, and a 60 watt Infra-Red night bulb is used when the day bulb is off.
---
The Temperature gradient is set up with the upper, back-right corner of the tank, being between 80-90 degrees F during the day, and 85-90 degrees F at night. The lower portion of the tank varies from 80-86 degrees F during the day, and 75 - 80 degrees F at night.  There is a 90-95 degree F basking spot day and night.
---
The humidity is Kept at roughly 60-75%. It is misted 3 times daily. Moisture is held in from the Substrate and the Moss. There is a water dish in the tank which is mostly for moisture from evaporation, as Tokay Geckos very rarely drink from still water.

Any Suggestions?

Answer
Hi Kris,

Thank you for including the detailed info about your set-up, that really helps. Clinging difficulties with arboreal geckos is most frequently caused by humidity issues which in turn causes shedding problems. If you are able to keep yours around the 70% mark, that is actually quite good.
You mentioned that you recently acquired her which leads me to suspect that she may have arrived with some unresolved shedding issues on her feet. It would be convenient if old shedding problems just resolved with the next shed after the humidity levels were corrected but it often doesn't happen that way. The old retained skin can continue to cause problems with the next shed cycle, even in perfect conditions. I have had people bring me snakes that had 3 retained eye caps on each eye, the first cap interfering with the two subsequent sheds. This is a particular problem with the smaller more intricately shaped areas like feet and toes. As you likely know, gecko toes are not simply suction cups but a series of delicate folds of skin. Once skin gets trapped in these structures more direct intervention is usually needed.

I would suggest soaking her and yes, I know how much fun it is to handle Tokay's! Confine her to a small enough container that forces her to stand in the water for at least 20 minutes or so. A few drops of glycerine (which is available at drug stores) added to the water can help. Examine her toe pads after the soak to see if any look different from the others. After soaking, retained skin will look quite whitish and obscure the normal structure of her toes. Often just giving it a gently rub with your thumb can help roll it off at this stage. In bad cases I have used tweezers to help remove it but extreme care must be used.
