I've heard sometime ago that if your water has too much minerals it will turn your laundry dingy. You might try a water softner. I believe you can get a filter installed or use chemical to soften your wash load.

Boil a half lemon in a couple of cups of water. Add it to your whites and let soak for an hour. They will look brand new.
