Exclamation Varnish in gas tank

OK, I 'f'ed up. I thought I had emptied the gas tank before I put the bike in storage. This morning I went to replace some of the fuel lines and when I opened the fuel petcock this really ugly smelly varnish dribbled out all over my hand.
Taking the tank off the bike is easy, so at least I don't have to worry about that. What should I use to flush out the tank and remove the varnish?

Turned out to be no big deal, there was only about 8oz on fuel/water in one side of the tank. I removed the tank and took off the petcocks, then I blasted a whole bottle of carb cleaner all around the inside of the tank until no more brownish goo came out. It looks like everything is alright, so the tank is going back on the bike.
Drama queens don't wear panties.
