Mud, snow and salt: how to protect your floors in winter

With the first snow, the floors of entrances, offices and shops change overnight. Wet footprints, mud from the pavement and white marks from the salt spread on the streets — it all comes in on shoe soles and gets carried everywhere. For business owners and building managers, winter is the hardest season for floor maintenance.

This article is a practical winter plan: how to stop the dirt at the door, how to deal with salt, and how to organise cleaning when the weather stays bad for weeks.

Why winter is so hard on floors

Winter dirt is different from summer dust:

• Water from snow makes the floor slippery and carries mud further.
• Mud dries into patches and sole marks.
• Salt leaves white marks that show especially on dark tiles, and can damage some floors.
• Sand and fine grit from gritted pavements scratch the surface under shoes.

On top of that, all of this happens just when people come in more often and stay inside longer.

The first line: mats

The most effective winter cleaning is stopping the dirt before it comes in. Entrance mats hold back a large share of the water, mud and salt.

Use at least two zones:

1. Outside — a coarse mat that scrapes off snow and heavy dirt.
2. Inside — an absorbent mat that collects water and what's left.

The longer the inside mat, the more steps a person takes on it — and the less dirt reaches the corridor.

Clean the mats often. A mat full of water and sand no longer holds anything and becomes a source of dirt itself. On snowy days it may need shaking out or drying several times a day.

The second line: cleaning the entrance more often

In winter the entrance and the corridor next to it need much more attention:

• Quick interventions during the day — drying wet footprints with a mop or an absorbent chamois cloth.
• Mopping the entrance — several times a day on bad days in busy businesses.
• A "Wet floor" sign — permanently at an entrance people walk into with wet shoes.

A fast-drying cleaner is especially useful in winter, because the floor is damp from shoes anyway. Cobra floor cleaners are low-foam and fast-drying and are designed for hard floor surfaces.

How to deal with salt

Salt is the most stubborn part of winter dirt. When the water dries, it leaves a white haze, and when it builds up — white ridges along the grout and around the mats.

What helps:

1. Don't let salty water dry. Dry wet footprints while they're still wet — that way the salt doesn't dry onto the floor.
2. Mop regularly. Regular mopping with solution at the right dose removes most salt marks before they build up.
3. Change the water often. In winter the water in the bucket gets salty and dirty very quickly. Salty water leaves the haze again.
4. Rinse with clean water for stubborn white marks — sometimes a second pass with plain water is needed.

What doesn't help: more cleaner. Overdosing adds more residue to the salt and the floor ends up both sticky and patchy.

Take care with sensitive floors

Salt and water are especially harmful to:

• Wood and parquet — water seeps in, and salt can leave marks.
• Laminate — especially at the joints between boards.
• Some natural stones — more porous types absorb salty water.

With such floors at the entrance, mats matter even more, and wet footprints should be dried immediately. For stone and wood, follow the floor manufacturer's recommendations.

Staircases in residential buildings

In apartment-building entrances, winter brings mud up to the top floor. Stairs need sweeping and mopping more often in the bad months, and the entrance landing needs a mat and drying. There's a detailed schedule in the article on cleaning entrances and staircases.

A winter routine for a business

In the morning, before opening:

• put down dry mats;
• mop the entrance and corridor;
• put up a "Wet floor" sign at the entrance.

During the day:

• dry wet footprints at the entrance;
• shake out or swap mats as needed;
• clean muddy patches straight away.

In the evening:

• main mopping of the entrance and corridors;
• dry the mats;
• wash the mops and leave them to dry.

Tools for winter

• A mop that wrings well — the ballerina-type microfibre mop for daily mopping; for collecting lots of water — the cotton mop. Comparison in microfibre vs cotton.
• A bucket with a wringer — the 12 L bucket.
• An absorbent cloth — a chamois for quick drying.
• Brush and dustpan — the brush with handle and dustpan for sand and grit.
• Gloves — household gloves; cold water and cleaners dry the skin even more in winter.

Stock up for winter

In winter, consumption of cleaner and supplies goes up — you mop more often and change the water more often. Consider a larger stock before the season so you're not caught out with no cleaner in the snowiest week. We show how to calculate consumption in the article on planning consumption.

In short

• Stop the dirt at the entrance with two mats and clean them often.
• Dry wet footprints before the salt dries.
• Mop the entrance more often, change the water more often, don't overdose.
• Protect wood, laminate and stone from salty water.
• Build up a larger stock before the season.

Frequently asked questions

How do I remove white salt marks from tiles?

Mop with solution at the right dose and then, if needed, go over it again with plain water. Change the water often — salty water in the bucket leaves the same haze again.

Why is the floor sticky in winter?

Usually from the combination of salt and an overdose of cleaner. Mop once with plain warm water and go back to the dose on the label.

How often should I mop the entrance in winter?

On snowy, muddy days — as often as it takes to stop the wet spreading inside. In busy businesses that can be several times a day, with quick drying in between.

Does salt damage tiles?

Glazed tiles and porcelain stoneware cope with salt relatively well if the marks are cleaned regularly. Grout, porous stone, wood and laminate are more vulnerable. Salt built up along grout is harder to remove, so don't let it sit for weeks.

Should I change cleaner in winter?

Usually not. A general-purpose floor cleaner at the right dose does the job in winter too. What changes is the frequency — you mop more often and change the water more often, not the cleaner itself.
