discoloured

It seems my wife loves wearing her leather coat whilst driving and having the heated seats on full. This has left what looks like the leather colouring ingrained into the grey leather of the car. Is there any product that can help remove this?

My Missus has just down the Bi-annual clean of the Merc:o and it has thrown up a couple of bits. With all the road repairs I have collected an amazing amount of tar on the car(either that or I have been melting the tyres:rolleyes:) does anyone have a good solution for tar removal? Product etc...

Changed my wiper cover yesterday and lubricated the workings The cover had discoloured The dealer charges £12 for the new one and it does look a lot better the plastic part above the cover is £8 Makes a big difference
