Firstly, it's good you've not let biting hamsters put you of, go slow with getting to know Munchie.
Start by putting your hand slowly into the cage and let him sniff you from a distance, try rubbing his wood shavings on you're hands so he doesn't feel threatened. If you still feel unsure try a pair of cotton gloves when giving him a treat.

One thing about hamsters is they can sense if you're nervous - so call him by his name and talk to him quietly and softly to let him get use to your voice and scent/smell at the same time.

Don't clean him out till he's use to you and maybe when you do decide to clean him out, clean little sections with him in the cage and let him get use to the cleaning spray smell.

In time he will trust you and vice versa and you'll bond. Good luck, keep us informed of your progress!
