I always just run pink antifreeze through the system until it is coming out the exhaust. This is done by running the engine with the hose to the strainer in a bucket of antifreeze. When I am getting antifreeze out the exhaust I run another gallon or two through then shut down. I change my zincs in the spring before launch and I have never had any corrosion issues, but I have only been doing it this way for the last 23 years. I am in Maine.
