2torial #0858: Learn2 Cut Down on Toxic Household Cleaners (continued) Replace descalers (mineral deposit removers)   Certainly the most effective way to stop mineral build-up in appliances and on surfaces is to treat the water where it enters, before it gets to them. Water softeners and conditioners are one way to do it. There are also electronic systems on the market now that you can check out. They use electrical and magnetic fields generated by a coil wrapped around the water inlet pipe. Neither this nor a water softener is a feasible option, though, if you rent your home. Clean a metal shower head by boiling it for 15 minutes in a half cup (about 125ml) of white vinegar and one quart (one liter) water to remove mineral deposits. If the shower head is plastic, soak it in an equal parts white vinegar and warm water solution for one hour. Clean out mineral deposits in tea kettles (electric or stove top), steam irons and drip coffee makers with a 50-50 solution of white vinegar and water. Operate the coffee maker as usual (let the irons and kettles stand overnight) and rinse well. To remove mineral build-up around faucets, lay a cloth soaked in hot white vinegar on the fixture that needs cleaning. Let it stand for an hour or so, and wipe it off.   Step 9
