Wash windows on a cloudy, but not rainy day. Working in direct sunlight causes streaks because the cleaning solution dries before you can wipe it off. This is the best time to vacuum the frames and sills. Cool, clear water is the choice of most professional window washers. If windows are very dirty you can add 2 to 3 tablespoons of vinegar per gallon of water. Use horizontal strokes on the inside and vertical on the outside so you know which side the streaks are on. for drying windows, a wad of crumpled newspaper works just as well as expensive paper towels. Wear rubber gloves to keep your hands free of ink.
OK, that is all and good and I have done all of that today but my question is.....
How can I keep my windows looking as good as they do right now????? Can I treat them with something that will at least fight the water spots from rain??????
I have a product that I used when we first put our new windows in about 2 years ago and I haven't washed the outside of the windows yet.
It's called Rain Block Glass Treatment. Bought it at Wal-Mart, but remember seeing it at auto supply stores, too.
It's in a black bottle with a spray pump (kinda like a fantastik or 409 bottle). The label is black with big red letters on it with what looks like a great lightning bolt in the background. It's a 20 oz. bottle and it's made by Value Smart Products.
I really like this stuff much better than Rain-X. Just follow directions on bottle. Works like a charm. Windows are still nice and clean on the outside. Have found that Hope's Perfect Glass window cleaner works better without hazing over after a while, too.
Here is a website for the rain block. Looks like they have changed the packaging, checked upc number and it's the same.
