Squeaky window, lubricate?

[MN Driver]

I've got a squeaky rear passenger side window on my car. It moves slower towards the top 1/3 of the track and squeaks a bit, sometimes more than others, depending on the temperature and humidity. I took a look at the track and it is clean, nothing stuck inside to slow it down. Is there a way that the window can be lubricated. I don't want to attract dirt so I assume oil is out of the picture. Possibly a waxy bike chain lube product, any ideas?

Buy a can of aerosol silicone spray and spray it liberally into the rubber run channels that the window goes up and down in. It will not leave an oily residue and should help the window move up and down a little bit better. I have used silicone spray for similar problems hundreds of times because it works and does not leave a mess that the customer would be angry about.
