How can you reuse a can of "Great Stuff" expanding foam by Dow?

You know that yellow expanding foam in a can you spray into gaps to insulate your home? Every time I use the can and put it away it is non-usably clogged the next time I want to use it. Once I was able to reuse a can by bringing it to work and using a combination of various solvents and compressed air, but I hope there’s a simpler way. Let me know if you know something that works.
