Rainbow Effect on Front & Back Screen

[ron130888]

Hoping for some tips or advice!

I recently purchased a 2012 Ford Focus and have noticed what I can only describe as a rainbow effect that is dried onto both the front and back screen - similar to when you see oil in a puddle.

It is mainly around the edges where the wipers don't touch.

I've cleaned the car several times now with shampoo, snowfoam and also used Autoglym glass polish which didn't make a difference.

Any ideas what else I could use or is this something that I will just have to put up with?

The windscreen itself smears quite easily when the wipers are used so hoping new blades will cure that side of things at least.

Thanks
Ronnie

Try cleaning it with a small amount of toothpaste on a wet screen.
