Stains on wood floors

Does anyone know of an approved method to clean salt stains off
historic wood floors?  The floors are pine and the building was
built in 1887. We've survived the recent snows and melt downs, and
now we have salt being tracked on the floors.  We have runners down
to keep people off the wood floor, but some salt and melted snow
manages to trickle over anyway.

I've tried wiping the floor with a mixture of distilled water and
.5% Photo-Flo 200 or .5% Triton X-100, wiping with distilled water
to rinse, and then drying with a clean cloth.  This method didn't

Perhaps it's not really salt on the floor.  Our maintenance guys
used calcium chloride, but then ran out of it and switched to salt.
Regardless, the stains are white.
