Here are a few more tried-and-true cleaners, courtesy of a Taste of Home magazine insert:
Carpet Freshener: Mix baking soda with cinnamon and sprinkle on carpets. Wait 15 minutes, then vacuum. (I have tried this and it works great!)
Mirror Cleaner: Clean with canned shaving cream (not gel) for a streak-free finish.
Scuff Mark Cleaner: Apply toothpaste to an old toothbrush. Scrub, then wipe clean with a cloth. (We also use a pencil eraser at our house for black scuff marks.)
Shower Door Cleaner (For Glass Doors): Clean doors thoroughly. Then wipe with baby oil on a soft cloth. The oil will prevent soap scum and hard water spots for months! (I have done this and can attest to it...it keeps them clean forever!)
