Here in NC, our tap water is 3.13x the national average in calcium content (it will leave noticeable water spots on car paint). Any chance the "hard" city water could cause the towels to be harder than necessary, causing micro abrasions on the paint, wood, etc? Technically there`s now calcium residue in the towels (and trace amounts of so many other things).
I don`t know if anyone has asked about this before or if an extra step could be to soak and ring out with distilled water after normal washing. Or, maybe vinegar would neutralize the calcium in the tapwater unless it causes some other damage to the towels? Maybe the whole thing isn`t even an issue, but couldn`t help but wonder considering the water spots the same water leaves around here.
