Now there is no more snow and ice (London) I've stopped using my Decosol screen wash. But just using plain water, I find leaves the screen a bit smeary.
It's been suggested to me that I put a bit of vinegar in with the screen water. Is this a good idea? It occurred to me that vinegar being acidic might well rot the rubber on the wiper blades?
Any suggestions that others have found a good remedy? thanks.
