Baking Soda is another great inexpensive product for cleaning. I use it most for getting rid of any foul smell that might come from my sink drain. I spill a little bit into the drain with the strainer in place to hold it. Then I pour in some vinegar and watch it bubble up. I follow this by a water rinse to wash the rest down. Recently, I was talking to a professional framer and her idea of the best, no streaking glass cleaner was equal proportions of denatured alcohol and water. I have not tried that yet but you can be assured I will. Don't be fooled by all the advertising/propaganda/marketing tricks that are there to make you spend YOUR hard earned money, on products that are wasteful, and potentially damaging to your home environment. USE COMMON CENTS!
