White Stuff on Rubbers

[Texas]

Not really noticed that this was as bad as this until I took a close look today, when windows are closed it looked like condensation on rubber surround behind window glass but was pure white, upon closer inspection it was a hard white deposit that did did rub off easily with a finger so used a damp sponge and then treated all window rubbers with some Wurth Gummy Pledge ( Rubber Fit) to moisturise! And it came up like new. It was worst on the windows that face constant sun when parked at home so I guess it is some sort of UV deterioration.

I had the same thing and put it down to the Wurth GP which I cleaned off and it's not marked up since.

I've always used this, never had an issue.

Am I reading you right? You reckon it Was the Gummi Pledge ( Rubber Fit ) that may have actually caused this deposit? Hmmmmm... Unless someone has used it on my car in the past this is the first time I have used it in this location!
