Drain the wash water and spin the clothes without agitating them. Finally, launder using the regular cycle, no detergent and 1 cup of water conditioner. If needed, repeat the laundering using 1 cup of water conditioner and no detergent until no suds appear during the rinses. If fabrics continue to be dingy, launder them with 1 cup water conditioner and a bleach that is safe for the fabric. Follow package instructions for the bleach.
Rusty water is caused by iron.
The iron may come from the water supply, from a water heater or from rusty metal parts in a well. Iron bacteria may also cause the problem. Iron can be dissolved in the water or suspended as particles. Chlorine reacts with dissolved iron to form particles of iron that settle out of the water. If the particles form in the washer during chlorine bleaching, they will deposit in the fabric and cannot be removed.
