Sloshing some around may be a good start but once you've done that, drain it off and get in there with dish soap and water and scrub it out. We're talking about a small portable tank for pete's sake. No need to spend a bunch of dough on chemicals. I've done this many, many times. I like Dawn Dish Detergent as it is a powerful degreaser. Once you're done scrubbing, rinse with water repeatedly and let dry. I use paper towel on the end of a flexible grabber thingy to swap out the last little puddles into the tank and collect debris. The final air dry takes less than an hour if it is warm.

Ethanol and methanol are great solvents, because of this that is what causes a lot of the ethanol in gasoline problems. They will disolve varnish deposits from old gasoline.
