I have a phone or two that have screen printed logos on them (e.g. see pic) that i want to remove as I am with a different carrier. I also just bought a HTC magic off trademe that I will run with Cyanogen firmware.



How can I remove these screen prints to have an unbranded phone?

I work in a lab so I have access to any kind of solvent, I just tried some ethanol and isopropanol, that didn't do anything as I expected (well it is a bit cleaner now).

I could progressively try stronger solvents until I find one that removes the brand but doesn't melt the plastic, but has anyone done this before?
