Switched to a different brand of roller guide cleaner and the noise difference is huge.

We had a bank of four cars in a 90s office building that all had a high-pitched squeal on the down run. After cleaning the roller guides with our usual stuff for years, I tried 'Trak-Silent' gel last week. The squeal on car three is completely gone after two full cycles. Anyone have a go-to product for stubborn guide rail chatter?

Ever have a noise so bad you could almost feel it in your teeth? Glad you found something that worked.

So you've been torturing people for years?

Actually it's been 17 years, and we call it "intense focus groups.
