I use paper towels. What I do, is keep some extra tubs on hand and as they are soiled, I replace with a tub and paper towels that has already been treated and dried. I take the tubs outside and spray them, then paper towels, with pam. I let the tubs and paper towels dry for 24 hours on my back porch, then take them back inside and store until I need them.

For cages, I remove all bedding, put the animal in a holding rack / tub, spray the inside of the cage and furnishings / paper towels, then leave the animal out for 24 hours. I don't return the water bowl until I add the animal back in. I have all cages and racks in the same room, so I do have to spray the cage while other animals are in the room, but I leave a ventilation fan running the whole time to help..I have not seen any negative effects from this.
