It's possible, though our hard water doesn't have this effect on non-synthetic whites. Perhaps if we wore the sport sunblock it would, though. We don't get pit-stains on our jerseys, just the sunblock stains. Shame, since SO many jerseys have white trim around the neck, which is the first place that yellows from sunblock.
