Another voice for OxyClean, marvellous stuff! I used to buy the generic brand from the Dollar General and that works almost as well. But really nothing works as well as OxyClean-very much worth the extra money!
THere is a remedy to well water. I had the same problem. With my regular washing detergent I add "Oxiclean".
I would start with having your water tested. Your local county extension office could tell you who would test it. It must contain a mineral that is in a higher concentration than normal, such as iron or sulfur. Once you find what that is, then you would have a better idea of what you may need to add to your wash to counter act that. It could be something as simple as just adding some epson salt, or vinegar, but if you add the wrong thing to some chemical it makes the problem worse.
