Ok…

My saddle has started Squeaking I am sure it so coming from where the rails enter to the rear of the saddle. It’s not a big squeak but it is a bit annoying, and I don’t like my bike to make any unnecessary noises.

Is there any way to stop this or fix it (but not get a new saddle)?

A bit of WD squirted in will stop it for a while, but as far as I know there’s no permanent fix for it.
I’d be happy if someone has a fix cos I have the dame problem on my commuter
