That if you have an old blood stain in your clothes, that you can soak it in hydrogen peroxide and it will come right out! I have found that it works great with almost all fabrics and it also helps if you wet the stained area in hot water before putting the item in the hydrogen peroxide solution.
That you can use denture cleaners to remove hard water/calcium stains in your commodes! All you have to do is drop one table in the commode and allow it to fizz. Let stand for about ten to fifteen minutes, flush and clean as usual. Use denture cleaner once weekly and watch your hard water stains disappear!
That placing used dryer sheets in your new and used books can ward off that musty paper smell! Just place a couple of used sheets in each book and you are good to go!
