Window lubricant

PostPost by: NYK » Tue Jul 27, 2021 7:30 am

I’m about to get my Plus 2 window frames back from the platers and will be rebuilding them with new channels/rubbers. I’m anticipating a high level of friction and the motors struggling to open & close the windows.
The obvious lubricants would be silicone or PTFE. What have others used and with what success?

I fitted new ‘silent channel’ (from Sue Miller) to my replated Plus 2 frames and also cleaned and re-greased the motor gearboxes. Didn’t do anything to the motors themselves. Windows operate as quickly and smoothly as on a modern car.
I’m not an engineer, but lubricating the furry channels doesn’t sound like a good idea, certainly not necessary in my case.

OK, that’s encouraging I’ve also bought the Sue Miller channels

NYK,

I had a series one Elise the workshop manual recommended a lubricant called Krytox, which I believe is a perflouropolyester, for the window channels.

Hope this helps,

I've used silicone containing furniture polish spray on a classic mini window channel. Seemed to work, No obvious draw backs

I thought I would start off with ptfe as it’s a dry lubricant and if that’s no good go to silicone

Don’t put anything on them as they don’t need it, the flock keeps the friction low. It’s when the flock wears off that you get glass to rubber contact and too much friction!

OK, thanks. I’ll do nothing initially then.
