Help! Crayon on TV screen!!!

[stripes1]

My 2.5 year old decided to colour in the TV today...wax crayons... Does anyone have any experience of successfully cleaning this off? Thanks.

Warm olive oil dipped onto a cotton cloth and wipe gently. Then glass cleaner/white vinegar onto another bit off clothand wipe off residue.

Thank you
Just tried this (though with a microfibre glass cleaning cloth) and it worked!
