Another pinner said...Wash outdoor windows with Woolite. I have been doing this for years and found a blog with photos. I use 1/2 cup to 1 gallon warm water, but other than that I do the same as this blogger using a soft car washing brush on an extension handle. Makes outdoor window cleaning easy. This sounds great...must try!
DIY Fabric Whitener It is SO simple and can’t believe that it works. You take one cup of cream of tartar (used in baking for some frosting to make them white, so that’s why this makes so much sense) and three cups of water. Mix together in a clean bucket and let your-at one time white shirts- soak and enjoy a fresh white shirt after washing in a regular cycle.
