Paper towels work fine, you just wind up going through a lot of them. And if you live in a dry part of the country, they'll dry out the air in the tank. But you do want them to cover the entire bottom of the tank, including under/around that water bowl.
So, I notice there's a bit of shed on that water bowl. How long have you had her, and has she ever shed for you?
Because I think that "white glaze" is probably stuck shed, because the humdity was too low... it's hard to be certain from a picture. Is she still striking at you? You can use gardening gloves to pick her up. Is the white stuff sort of a crinkly layer of extra skin?
If yes: then I would fill a bathtub 2 inches deep with room temperature water, put her in it, and make her swim for 5-10 minutes. (She'll try to escape, but just keep putting her in the water until she's good and soaked.) And then you either peel it off if she's cooperating, or put her back in her tank and see how much she gets off herself.
One of the problems with paper towels is they do dry things out. So in the future, if you see her going into shed, you want to get a spray bottle and spray the tank down once a day until she sheds.
