If your showerhead seems to be sputtering, a buildup of mineral deposits may be clogging the holes. Do not but a new showerhead if you have some vinegar in the kitchen. Place the showerhead in a pot and add enough vinegar to cover it well. Heat the vinegar to just below boiling, then turn off the heat, and let the showerhead soak for about eight hours. As it sits, the acid in the vinegar will eat away the deposits. Rinse the showerhead, and it is ready to use. You can use vinegar to clean the outside of your toilet and around the base of the toilet to keep it fresh. If your radiator has a clogged valve, clean it with vinegar. First, shut off the valve then turn it counterclockwise to remove it. Place the valve in a pan of vinegar and boil it on top of the stove for twenty minutes. By then, the calcium deposits blocking the valve will have dissolved. You can also wipe your windows squeaky clean with a little vinegar on a clean cotton rag. You will get a clear streak free finish.
