Antifreeze...

Went on a little road trip the other day and got the oil changed along the way. Found out today that the moron working there apparently put some anti-freeze in the windshield washer reservoir. What's the easiest way to flush it out? No more quick lube stops for me. Ever.

Isn't there a plug on the bottom of the reservoir?

Take a water hose, insert, turn it on till it runs clean... pretty simple.

Disconnect your tubes and run them into a can of some kind. Run it dry. Less mess.
