Answer 3

Problem: Hard Water

Laundry Symptoms:

Dinginess or graying, yellowing

General soil build-up

Stiff, harsh feel to fabrics

White or gray streaks on colored fabrics

Calcium and magnesium are usually the minerals that make water hard. The greater the concentration of these minerals, the harder the water. Hard water doesn't clean as effectively as soft water. In hard water much of the detergent added to the washer goes to soften the water instead of to clean the clothes. This means that more detergent must be used than in soft water. Softening water by using more detergent has two drawbacks; it is expensive and if the detergent contains phosphate it can add to water pollution. Heavy duty liquid detergents will remove soil in hard water almost as effectively as powdered phosphate-built detergents and they do not contribute to water pollution. Non-phosphate powdered detergents and soap do not perform satisfactorily in hard water.

Solution: To prevent the problems caused by hard water, take two actions. First, use adequate amounts of low-sudsing phosphate detergent or heavy duty liquid detergent and water as hot as recommended for the fabric since all detergents perform better at higher temperatures in any quality water.

Second, soften the water. Water may be softened in the washer with nonprecipitating ion-exchange water conditioners, commonly sold in grocery stores simply as water conditioners. Water softener systems which exchange sodium for calcium and magnesium may also be connected to the water supply lines for the washer, the kitchen, or for the entire house. However, persons 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.

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 phosphate detergent and one cup on nonprecipitating water conditioner. Agitate just long enough to wet the clothes. Soak overnight or for about twelve hours. Drain and spin without agitating. Launder, using regular cycle, no detergent, and one cup of nonprecipitating water conditioner. If needed, repeat the launderings using one cup of nonprecipitating 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 nonprecipitating water conditioner and bleach which is safe for the fabric, following package instructions for the amount of bleach to use.
