I'm taking apart an old rear projection TV to get rid of it piece-wise.

There are some clear, odorless, liquid CRT coolant sealed on top of each
CRT. I accidentally spilled some inside the cabinet. What is the proper way
to dispose of these liquid?

According to one web site, it contains ethylene glycol and glycerine. Should
I mix it with with my car's old coolant and recycle it?
