I was trying to clean a window this morning that gets a lot of splash marks from watering a nearby hanging basket. The marks were impossible to clean off and I was worried that maybe the double glazing was damaged.
Then I had the bright idea to try Viakal. I sprayed it on to the wet Karcher pad then vacuumed it off in the normal way.
Wow! What a result! I've never had such sparkling glass so I did all the others as well. We live in a hard water area so I really should have thought of it before. It also worked by just spraying it on a damp eCloth to wash the window then wiping it off with a dry one. No smears!
Has anyone else tried this?
