We have a community well. We moved here two years ago. Since then, all bedding, sheets,pillowcases, mattress covers,mattress pad, all have body stains like sweat which will not wash out. The stain goes all the way through the pillowcase onto the pillow..very yellowish. Also, after a time, the showers, tubs, and sinks get a blueish hue, which is removed with bowl cleaner. What can we do in the laundry to whiten, or eliminate the stains?
