green door

[RAMEAUX]

I have a double glazed front green door which gets a lot of direct sunlight and as a result the normal bright shiny surface is fading with a dull whitish covering. I have tried a white PVC cleaner which does work but due to the grain effect on the door it leaves a trace in the grains.
Does you all know of any coloured (green) PVC cleaner and where I can find it .

Appreciate all replies and tips to resolve this

Hmm. Colour Magic car polish, maybe?
