Maybe do frequent water sprays in the Viv / rub or try soaking ...
I have done the occasional 25 minute soak , in 86F temp water , in a sealed container - obviously leaving air space at the top but if it's a few inches deep they tend to happily spend most of the time underwater.
I have a container that has clasps on the top so it's safe to place it in the towel cupboard - which is warm and dark .
They wiggle about looking to escape for a minute or two but quickly calm down . On release I have a wet , rough textured towel ready and let the snake slither continually through the towel , when it's head appears I simply cover it up with the towel .
Anyways after the soak any dead skin or retained eye-caps simply comes off nice and gently on the towel ( has to be rough textured ) ..
