Hi Nigel...welcome to the Forum

I would recommend TFR (Traffic Film Remover) but specifically the trade (undiluted) one available from valeting trade suppliers.

Apply it neat (wearing goggles to avoid getting in your eyes...ouch!) and leaving it on for a very short time before washing off.  Don't leave it on for too long as it will bleach the paint and avoid getting it on the external paintwork.

Then work your way down to a more diluted mix to remove any other light staining.

Let us know how you get on with it
