My friend has a Honda Aviator STD.
He gave it to his cousin for a week and when it came back, we all were surprised to see what happened.
The thing was that all plastic parts (handlebar, mirrors, etc) were is pityful condtition ; which white marks on them! My friend asked his cousin about the marks on the scooter and he replied : I used scratch out (scratch remover) on the plastic parts too
My friend tried to clean it with running water but no improvement. 3 days have passed and still the marks are visible.
He was asking for suggestions to remove the marks conveniently and instantly.
