Got to my 1st clean today where a rose bush grows by the window. Usually use this stuff I have to get it off but having cleaned the Astra out yesterday forgot to put stuff in. So's set me thinking. What I did was pour a small amount of vinegar on my applicator with soap and it came off a treat. Not only that I also noticed that during the day my windows were IAbsolutly sparkling with this method & yes there's more, your squeegee glides over the window with the minimum of effort. Will be doing this each morning now. Thought I'd share this bit of good fortune with you & maybe try it. Do NOT do of you can't stand smell of vinegar but that goes after a couple of minutes. Just pour a small amount the length of your applicator.
