Just been looking at  MIL's nissan micra  and it needs a dit of a deep clean. Any recommendations for getting "green" off the windows/ trim. It was parked under a tree in the shade for a few years and was covered in green algae, some of this washed off with car shampoo the remaining bits seem very well attached.

It will need a liberal spray of APC and follow that with a very soapy wash with car shampoo and claying

All this prior to polishing and then applying a wax or sealant
