If you have Find My iPhone activated on the iPod, so long as it is an iPod Touch, and it is connected to the internet, you can wipe it from iCloud. See the instructions here, If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support
My daughter forgot her passcode on her iPod and we can’t connect to iTunes. Is there a way I can wipe/restore her iPod from my phone?
