Just cleaned the Z4 for the first time, and used brasso on the headlights and they are like crystal clear.
A lot of elbow grease and had to go over them like 4 time but so worth it.
Just wish I did a before and after picture
I used a micro fibre cloth that worked well and washed the lights with just warm soapy water.
I will add a picture tomorrow. Saw 4 Z4's today driving in bury st Edmunds today. Never really noticed them before.
