Never tried this but it's got to be worth a try ...
If all fails .... sit down somewhere with a wet or very damp , rough textured bath towel and wrap the snake up in it ... then let it slither around inside a while , all the time you can be applying very GENTLE pressure on the head / neck / eye regions and after 5 to 10 minutes any stubborn dead skin and eye caps will have been removed ..
Just takes some patience and a very gentle touch.
Do not be tempted to simply pull any skin off with your fingers as some snakes will ' have you' as it hurts sometimes.
Another tip I see for retained eye-caps but DISAGREE WITH - is to put some tape over the eyes and gently pull !!
This sounds like an horrendous idea !!!
