Winter salt stains: how to remove them from tiles, vinyl, wood and carpet

You can remove salt stains from a floor in two steps. First, vacuum or sweep up sand and salt crystals dry, so that they do not scratch the surface. Then mop the floor with lukewarm water and a well-wrung mop, change the water often, and finally go over the surface with clean water and dry it. Acidic cleaner is only for ceramic tiles, not for wood, laminate or vinyl. On carpet, blot the stain with a damp white cloth and do not scrub it.

Why road salt leaves white stains

Road salt dissolves in melting snow on the pavement, and the salty water is then carried into your flat on shoes and pushchair wheels. When the water on the floor evaporates, the salt dissolved in it stays on the surface as a white film, rings around droplets or grey streaks.

Along with the salt, sand and grit from the gritting are also brought indoors. Under a sole, these grains act like sandpaper. In its care instructions, the wooden floor manufacturer Barlinek states that sand brought in and spilt liquids have a very negative effect on the floor and must be removed immediately. This applies to other surfaces too, but the stain is removed slightly differently on each.

A white film that returns even after mopping usually means that you have only spread the salt over a larger area. Changing the water more often and finishing with a pass of clean water will help.

What to prepare

• a vacuum cleaner with a hard-floor nozzle, or a broom and dustpan,
• two buckets: one for washing, the other for clean rinsing water,
• a microfibre mop or cloth that wrings out well,
• a dry absorbent cloth or towel for drying,
• white cotton cloths for the carpet (a coloured fabric may bleed onto a damp carpet),
• a cleaning product intended for your type of floor, as recommended by the manufacturer,
• rubber gloves, if you will be working with an acidic cleaner.

Basic method for all hard floors

1. Dry first. Vacuum or sweep up sand and salt crystals. If you mopped straight away, the grains would move under the mop and scratch.
2. Lukewarm water. Salt dissolves in water, so lukewarm water is enough for most fresh stains. Wring the mop out well; the floor should be damp, not wet.
3. Change the water often. There is a lot of salty water near the entrance. Empty the bucket as soon as the water turns grey, otherwise you will spread salt all over the hallway.
4. Rinse with clean water. Go over the area once more with a mop dipped in clean water. This removes the dissolved salt and any product residue.
5. Drying. Wipe the surface with a dry cloth. If a white haze remains after it dries, repeat steps 2 to 4.

Only when clean water is not enough should you reach for a cleaning product, chosen according to the type of surface. Follow the label, ventilate the room and test the product first in an inconspicuous spot.

Method by surface

Ceramic tiles

Tiles tolerate salt best, but stains quickly reappear in the pores and in the grout. For ordinary dirt, the tile manufacturer RAKO recommends a neutral product, and for limescale and mineral deposits an acidic product. According to RAKO, before using it you need to wet the surface and the grout thoroughly with clean water and, after cleaning, rinse everything several times so that the product is neutralised and its residues are removed.

RAKO also warns that incorrect application of a cleaning product can damage the ceramic surface, the grout and elastic sealants. For this reason, do not use acidic cleaner on polished tiles or on cement grout unless the manufacturer of the tiles or the grout expressly permits it. Do not use it on natural stone at all: the Natural Stone Institute states that marble, travertine and limestone react badly to acid and the surface becomes etched. Stone calls for a pH-neutral cleaner intended for natural stone.

Wet tiles are also slippery. According to RAKO, sand, grease, snow and ice significantly reduce the slip resistance of the surface, so keep mopping the entrance dry throughout the winter.

Laminate

Laminate is mainly harmed by water that seeps into the joints. In its instructions for cleaning a laminate floor, Quick-Step recommends vacuuming once a week, mopping with a damp mop and mopping the planks lengthwise. It does not recommend natural soap-based cleaning products, products with abrasive particles or disposable pre-soaked wet wipes. Wipe off a salt stain with lukewarm water and a wrung-out mop, and do not leave water standing in the joints.

Vinyl

Vinyl tolerates water better than laminate, but sand can scratch it. Mop it with a damp mop and use only cleaning products approved by the manufacturer of your floor. It is best to avoid soap-based and abrasive products unless the instructions expressly allow them. For both vinyl and laminate, follow the instructions for your particular floor.

Wooden floor

Wood is the most sensitive to water and salt. Remove stains as soon as possible, mop only with a well-wrung mop and do not leave water on the floor. In its care instructions, Barlinek warns that the floor should be treated only with products intended for it, and that other products may cause stains, discolouration or slipperiness. Therefore do not use vinegar or all-purpose cleaners on wood unless the manufacturer of your floor expressly permits them.

If a grey or matt patch remains after drying, the lacquer or oil may be damaged. That is more a matter of restoring the surface according to the manufacturer's instructions. You can find more about routine care in the article how to clean a wooden floor, laminate and vinyl.

Salt stains on carpet and doormats

On carpet, salt clings to the fibres and, once dry, forms hardened white edges. Proceed as follows:

1. Let the area dry completely and then vacuum it thoroughly. This removes a large part of the crystals and sand.
2. Dampen a white cloth with lukewarm water and blot the stain from the edges towards the centre. According to the Carpet and Rug Institute, you should not scrub or brush the stain, because this damages the carpet. Just blot it repeatedly.
3. If water is not enough, use a carpet cleaner according to its label. The same source advises testing any cleaner beforehand in an inconspicuous spot, applying a little to a white cloth and gently working it in from the edges towards the centre.
4. Finally, blot the area once or several times with a cloth dampened with clean water so that no product is left in the carpet, and then let it dry.
5. Once it is dry, vacuum again and comb the fibres with your hand.

If the stains cover a large area or return after every cleaning, it is time for deep cleaning. When and how to go about it is described in the article how to clean a carpet at home and when it is time for upholstery and carpet shampooing.

In winter, shake out or vacuum the doormats at the entrance more often. If the manufacturer of the mat permits it, rinse it with water from time to time and let it dry away from the floor, so that salty water does not run underneath it.

Safety: what not to mix

In its overview of commercial products, the Toxicology Information Centre warns, for toilet cleaners containing sodium hypochlorite or acids, not to mix them with each other, as chlorine gas may be released. Never combine an acidic tile cleaner with products containing chlorine, and do not mix chlorine products with ammonia either. As a general rule, follow the manufacturer's label and do not mix different products. Ventilate while working and wear gloves. You will find details in the article which cleaning products you should never mix.

Prevention: doormats and removing shoes

The least work comes from salt that never gets into the flat at all. The Carpet and Rug Institute recommends stopping dirt at the door with mats outside and inside, and by removing shoes. In its instructions for cleaning laminate, Quick-Step likewise advises placing a mat in rooms entered from outside, so that the floor does not need to be cleaned as much.

• Two mats: a coarse one outside for sand and snow, an absorbent one inside for water.
• A place for shoes: a tray or mat for wet shoes right by the door, so that salty water does not drip onto the floor.
• Removing shoes at the entrance: agree with your family and guests that shoes are left at the door.
• Pushchairs and bikes: wipe the wheels with a cloth at the door before taking them further in.
• More frequent cleaning of the entrance: in winter, vacuum and mop the hallway every day or every other day.

Hallways in apartment buildings and common areas

In the entrances of apartment buildings, salt is brought in every day and stains return quickly. A large cleaning zone behind the entrance door and regular winter mopping suited to the floor surface help. If you would like to outsource hallway cleaning, Úklid 1-2-3 offers cleaning of common areas. You can check the scope and price in the price list.
