Hard water washing
My hard Phoenix water continues to confuse my laundry routine. (Metro area hardness varies from 12 to 20 grains per gallon, where anything over 10.5 is "very hard".) I've just joined up so I can poll the laundry gurus for ideas!
Any tips to maximize cleaning and minimize residue? I've just read that carbonates are a bad idea in hard water. But my White King softener is a mix of sodium carbonate and tripolyphosphates. Also, is vinegar in the rinse a good way to help eliminate residues?
I use liquid Charlie's Soap or liquid Country Save. My rental home came with the laundry machines, and the washer is an older Maytag (Heavy Duty Large Capacity) with only a Regular and a Permanent Press cycle.
Thanks for any suggestions!
