Does anyone know the best way to clean the iscv out as mine is seized up ive got the slider inside free again but when connected nothing visibaly happens and i recall the last time i had one out and the ignition was switched on it moved cheers

 

I am not sure about the name in english... but concentrated soad used before a paintjob is VERY good.. it takes away carbon to and so. I have tryed it my self.
