Beating Stubbon San Diego Hard Water Stains On Dishes
San Diego residents often mistake the powdery white film on glasses and dishes for soap. Its actually a more tenacious issue known as lime scale caused by hard water. San Diego county plumbers get calls every day about this stubborn film.
Unfortunately, America’s Finest City consistently ranks among the top 10 U.S. cities with the worst water quality. This low ranking is primarily due to hard water. Our water travels a long way from the Colorado River and other sources. By the time it makes it to our dishwashers, it’s picked up calcium, magnesium and other elements. When interacting with hot water, these substances convert to an alkaline lime scale that can be hard to remove.
Attack this annoying lime scale from many angles.
- Dishwasher water temperature should be 120°. Check your water heater to see if it is set this high.
- Is the dishwasher or other dish detergent fresh? You may be surprised to learn that dish detergent lasts only one year. If you stocked up because of a sale, your detergent may no longer be effective.
- Is your water pressure adequate? Your home water pressure in San Diego should be 40 to 50 pounds psi but not greater than 60 psi.
- Counteract the alkaline residue with a safe, natural acid. A cup of white vinegar in a Tupperware container in the top rack of your dishwasher every time you do the dishes provides the acidity to counteract tenacious, but alkaline, lime scale. San Diego plumbers are always astounded that clients haven’t heard of this old home remedy that really works! (or helps at least)
- Could your water heater need flushing? When water heaters break and leak water onto the garage floor, San Diego homeowners tell us a whole lot of sand came out! Sediments build up in your water heater to such an extent, it seems as if a pile of sand has accumulated. Unfortunately, this pile in your water heater is distributing microscopic particles with every wash or shower. Flushing your water heater removes all this sediment lowering the metal content in your water.
- Consider a water softener
According to the California Department of Public Health, San Diego’s drinking water system contains eight chemicals falling outside of its health guidelines and two chemicals that exceed the EPA’s legal limit. It’s the presence of these substances that, not only causes lime scale, but land us on the worst drinking water quality list every year.
To counteract impurities and sediments, many local families install a whole house water softener, also known as a water filter. A whole house water filter removes the taste and odor of chlorine. It also reduces lead, mercury, microbial cysts and agricultural pollutants.
Softened or filtered water not only tastes better, it cleans dishes and laundry more efficiently. More, it cleanses your skin of pollutants rather than pouring more on.
