Hi
I am using Turtle Wax Extrem Car Shampoo to wash my old Rover 600. This leaves some unbelievable smears on the car. On my Scenic though , it come sup a treat. I have washed the rover several times with less and less turtle wax in it (half a cap per gallon bucket at the moment) and it still happens.
The streaking appears to be too much soap. Will this caus elong term damage to the paintwork and how can I get rid of all the residues on the car before trying one last time.
