Tip for cleaning side windows

[Swiss_Toni]

FYI, my race engineer gave me a tip for polishing up the side windows, regular car polish!

I gave it a go and with little effort they went for a bit hazy to bright and clear.

Aparently regular window cleaner makes them go hazy.

A bit of a result, and it was cheap and easy for a change!

I've also got proper plastic window cleaning stuff but they never got better, just didn't get any worse.

I just used some autoglym, I'd don't know how aggressive you can go. You may need to then polish up with normal car polish.
