Can this DISGUSTING La Pavoni Europiccola Pro be saved? (rescuing a friend in need)

This is some quick first aid on a grimey Europiccola Pro pre-millennium model. Not only does it look disgusting but the lever barely moves - time for some much needed cleaning and maintenance. If you're curious what a drip tray looks like if you don't clean it up, look no further! If you're squeamish, look away! If this is a normal sight and you let your drip tray get this bad all the time... there is hope for you too.
