Are your clothes, sheets and towels dingy or do they feel harsh to the skin? Do you have powdery residue left on clean clothes. The problem could be the water you are using to wash clothes. Learn about how to handle hard water and laundry.
What is Hard Water?
Hard water is found in 85 percent of America. Hard water is usually defined as having high levels of calcium and magnesium; the greater the concentration of these minerals, the harder the water.
With a high concentration of these minerals in the water, unless the water is treated the calcium and magnesium attach to fabric in a laundry load and leave clothing and linens feeling stiff and covered with a residue that dulls color. In excessively hard water, the fabric fibers can actually break and create holes due to the amount of mineral coating.
If you are on a municipal water system, the officials can share with you the level of mineral content in your water supply. There are also water testing kits available that you can use at home, as well as, companies that will test your water supply. Testing is particularly important if you use well water.
Hard Water Laundry Problems
- Dinginess or graying, yellowing
- General soil build-up
- Stiff, harsh feel to fabrics
- Weakening of fibers causing tears
- White or gray streaks on colored fabrics
How to Use Laundry Detergents and Hard Water
In hard water most of the ingredients in any laundry detergent become attached to the minerals in the water rather than cleaning the clothes.
This means that more detergent must be used and at a higher water temperature than usual to get satisfactory cleaning results. Having to use more detergent is expensive and higher water temperatures can damage clothes and costs more money in energy bills.
If you have hard water, you can use any detergent but it is particularly important to select a heavy-duty detergent that offers the most cleaning ingredients.
You'll have much better results than with a bargain brand.
If you are having a problem with white residue produced by powdered detergent that did not dissolve well in hard water, try switching to a liquid detergent.
You can also add 1/2 cup of laundry borax to each load. Borax provides water softening by producing (forming a chelate with the minerals so that they are no longer available for reactions) a soluble calcium complex and boosts surfactant performance by preventing precipitation of a calcium/surfactant complex.
Homemade laundry detergents often rely on pure soap as a basic ingredient. Unfortunately, soap does not perform well in hard water. If making homemade laundry detergent for use in hard water areas, increase the amount of borax by at least one third to produce better cleaning. You may need to test and adjust your formula to include even more borax.
How to Make Laundry Water Softer
So rather than using more detergent, water may be softened in the washer with nonprecipitating ion-exchange water conditioners, commonly sold in grocery stores simply as water softeners or water conditioners. If you cannot find them locally, water softeners can be purchased online from Amazon.
Water softener systems which exchange sodium for calcium and magnesium may also be connected to the water supply lines. However, those on sodium-restricted diets should consult their physicians before adding a water softener system to lines that supply water for drinking and cooking because the sodium content of the water will increase.
According to the Water Quality Association, laundry detergent use can be cut by 50 percent and washing machine temperatures lowered from hot to cold by using softened water.
Two studies, conducted by the independent testing firm Scientific Services S/D of New York and funded by the Water Quality Research Foundation (WQRF), reveal that by using softened water in washing machines, detergent use can be reduced by 50 percent. In softened water, water temperatures can be reduced to 60 degrees F.
or cold water instead of 100 degree F. hot water and still achieve the same or better stain removal and cleaning.
Researchers used varying levels of hardness and several different name brand detergents in washing machines. It was found that significant savings was noted for all levels of hardness, even hardness as low as 5 grains per gallon. In a look at stain removal, half to the entire amount of manufacturers' recommended levels of detergent was added. Water hardness ranged from none to 30 gpg, and wash temperature was 60, 80 and 100 degree F. It was found that using softer water is better at removing stains than increased water temperature or more detergent being used.
Fixing Hard Water Laundry Stains on Clothes
If you have not installed a mechanical water softening system, to remedy problems that have already occurred, fill the washer with the hottest water appropriate for the fabric. Add four times the normal amount of detergent and one cup water conditioner. Agitate just long enough to wet the clothes. Soak overnight or for about twelve hours. Drain and spin without agitating. Launder the garments, using regular cycle, no detergent and one cup of water conditioner.
If needed, repeat using one cup of water conditioner and no detergent until no suds appear during the rinses. In order to remove all dinginess it may be necessary to launder with one cup water conditioner and a bleach which is safe for the fabric, following package instructions.
To remove white residue mineral and detergent stains, soak in solution of one cup white distilled vinegar to one gallon of water for 30 minutes. Rinse thoroughly, then launder.
Chlorine Bleach and Hard Water
Many times hard water contains iron particulates which when combined with chlorine bleach produces iron oxide or rust which can stain clothes. Learn more about about how to handle this type of hard water and how to remove the stains using a rust stain remover.
