But, I'd be interested to see what would happen if EDTA was added to water used to wash bikes.
Most cities use Halite or coarse sodium chloride, aka rock salt. Basically the same stuff in the sea and on your table. Some cities are moving away from salt to eco friendlier (or claimed to be) organic deicers, but I have no idea of the chemistry. Here in NY it's mostly salt.

I don't know about lime sacle removers, having never tried them for salt.
