General rules for cork flooring

Get the spill up before it finds a tile edge, because cork tiles have joints all over the floor.

Clean with a barely damp cloth and dry immediately. Cork is soft, so abrasive cleaning cuts through the seal quickly and then the material underneath absorbs.

If the floor no longer beads water, the seal has worn and resealing is the answer rather than more careful cleaning.

Check the label

Cork is a soft, cellular material sealed with a lacquer or a wax, and the seal is doing all the work. Cork itself absorbs and swells, and a worn or broken seal on a traffic route or a tile edge is where a spill gets in.

Stains on cork flooring

Cork flooring is compressed cork bark, laid as tiles or as a floating plank, sealed with lacquer or wax.

The seal is the surface

Cork itself is absorbent and compressible. Everything that keeps a cork floor usable is the finish on top of it.

It is soft

So abrasives cut through the seal quickly, and once through, the cork beneath absorbs and swells locally.

Tile joints are everywhere

A cork tile floor has a joint every 300 millimetres, so a spill finds one within seconds.

It can be resealed

Lightly sanding and recoating a cork floor is normal maintenance, which makes a worn seal a routine job rather than a disaster.

  1. Luxury vinyl tile care guide, Tapi retailer

    UK flooring retailer guidance to avoid steam cleaners and overly wet mops on smooth flooring because steam forces moisture into the joints and lower layers and causes warping, to avoid cleaners containing harsh chemicals, ammonia or wax and abrasive materials because they permanently damage the surface, to spot test any new cleaner, and that the wear layer on LVT cannot be refinished the way engineered wood can.

    Linoleum manufacturer guidance not to over wet the floor when cleaning, that all cleaning solutions must be pH neutral between 7 and 8 because highly alkaline or acidic solutions are harmful to the floor, never to use abrasive liquids, powder cleaners or scouring pads, and to avoid steam cleaning equipment, undiluted solutions, strong solvents such as acetone and soap based products.

    UK wood flooring maker's guidance to clean spills immediately and not leave wet items on a wood floor, to damp mop with a well wrung mop or a barely dampened microfibre cloth, that steam cleaners and steam mops are not recommended, that oil based, wax based and ammonia based cleaners can damage the floor, and that an oiled floor is maintained by reapplying maintenance oil and polishing it until the surface looks uniform.
