Squeaking windows...

[AAPete]

The windows on my CLK squeky terribly when they go down, any tips/tricks how to stop it?

Usually caused by green gunk on the door seals. I get a razor blade, wet the rubber down, and cut the lichen off.

Spraying the window guides with silicone lubricant helps as well.

Thanks for that...
