I'm surprised Ponds Cold Cream doesn't get the waterproof mascara for you, because that's the only thing that gets rid of the most stubborn products completely for me!
I buy 100% Jojoba Oil by Desert Essence at Trader Joes (it's like $7 or something like that) and use it as my makeup remover. It's very nourishing but gets rid of every last speck of makeup for me. Plus, you can use it as a multi-tasker as a nourishing hair/scalp mask or a facial moisturizer.
