While doing a recent garbage disposal project I decided to look at the pull out spray head on the kitchen sink. Over the years this had become hard to pull out and the tubing would get caught occasionally.

I found a good spray silicone based lubricant has worked wonders making the spray head easy to pull out. I did not want to use WD40 as it is petroleum based and I was concerned it might damage the rubber/plastic in the flexible tubing. Also once I got the spray head moving easily I noticed it was occasionally catching on the supply pipes. I tried several approaches to keep the weight away from these pipes, all of which worked the first pull and not of which worked after that, then I noticed if I put a quarter turn on the flexible line where it connects to the sink the problem was solved completely. The weight now goes between the drain line and the cold water supply line and does not get caught.
Hope this helps someone else with a similar problem.
