From November to April, every floor in a Wisconsin or Minnesota building is being cleaned by whatever came in on the last pair of boots. That is the real maintenance program for six months of the year, and it is why two identical buildings waxed on the same day can look completely different by March.
It helps to know what you are actually fighting. Ice melt is not simply dirt. Sodium and calcium chloride are hygroscopic — they pull moisture out of the air and stay wet — so a salt residue on a floor keeps working long after the slush has dried. On a waxed floor that means a white haze that a normal mop pass will not lift, and under the haze a finish that is being chemically softened rather than just scratched.
Sand and grit do the mechanical half. Every step grinds them into the finish like sandpaper, which is what cuts traffic lanes through a wax build and greys out the carpet between the door and the counter. By February those lanes are usually the only part of the floor anybody notices.
The single most effective response is matting, and most buildings do not have enough of it. The rule of thumb is fifteen feet of walk-off matting inside the entry — long enough for someone to take three or four full steps before they reach the finished floor. A three-foot mat at the door is decorative; it catches the first step and nothing after it. Scraper matting outside, absorbent matting inside, and both of them actually cleaned rather than left saturated, because a soaked mat stops absorbing and starts distributing.
Second: mop water and chemistry. Use a neutral-pH cleaner as the daily routine, and change the water far more often than feels necessary — in winter, mop water goes grey in a fraction of the usual time, and once it does, mopping is just redistributing salt. For visible salt haze you need a dedicated neutralizer or a mild acidic cleaner; a stronger alkaline degreaser will look like it worked and will take some of your finish with it.
Third: get the grit off before it gets ground in. Dust mopping or vacuuming a hard floor daily through winter does more for the finish than any amount of scrubbing later, because most of the damage is abrasion, and abrasion only happens once the grit is underfoot.
For carpet, the same salt is what makes lanes go grey and crunchy, and it does not vacuum out — vacuuming removes loose soil, but chloride has dissolved into the fiber and re-crystallized there. Hot water extraction is what actually flushes it, and mid-winter extraction of just the entry and the main lanes, rather than waiting for a spring clean of the whole floor, is the difference between carpet that recovers and carpet that is permanently dulled.
Plan the year around it. Get a scrub and recoat done in late autumn so the floor goes into winter with full film thickness, keep matting and daily grit removal tight through the season, and book the strip or the deep recoat for spring once the salt has stopped coming through the door. Stripping a floor in January is work you will be repeating.
One thing worth checking on your own floors right now: look at the tile a few feet inside your main entry, where the mat ends. If the pattern there reads sharper and slightly different in color than the tile ten feet further in, the finish is already gone in that band — and that is where every winter starts.
