Creaking Leather

[headhurts]

Following a seat replacement some while ago thought I would treat the leather to a coating of superguard, I used the leather wipes which cleans and protects..

Since doing this the side of the seat creaks against the side trim of the seat where the electric seat switches are.

I have tried leather cleaners, conditioners and even wiped silicone spray over it and although it is better the seat still creaks against the trim.

What I need is either something that will completely remove this product or an item that will make the leather slippery enough to stop the noise but not harm the leather.

So far have tried turtle wax leather cleaner and conditioner, DFS leather treatment for furniture, Autoglym cleaner and conditioner, Gliptone conditioner and silicone spray.

Could anyone suggest a product that may help ease this creaking sound possibly an oil that will soften and remain on the surface.
