Steam cleaner
Heat and moisture applied together, with no chemical at all. Both are the point, and both are what several manufacturers prohibit it for.
What not to do
Steam cleaner should be avoided for Laminate flooring
Best avoided
The available guidance advises against this.
Precautions
- Check the manufacturer's instructions
Why we say this
Supported
Steam is moisture plus heat delivered at a joint. The producers' association's damp-not-wet instruction is what this edge carries.

In detail
A steam cleaner works by delivering hot water vapour to a surface, softening greasy and sugary soil and loosening what has bonded to a hard surface, with mechanical wiping doing the rest. The absence of a cleaning agent is its genuine attraction — nothing is left behind to attract soil — and heat plus moisture is exactly why it is prohibited on more surfaces than most tools. A contract furniture manufacturer's textile guidance carries a categorical instruction not to use steam on the fabrics it covers. Wood-floor and laminate guidance excludes it because moisture at the board joints swells the core and lifts the wear layer, and the damage is not reversible by drying. On a sealed or waxed finish the heat softens the finish itself. And where a surface is a coating rather than a solid — a printed vinyl, a lacquered metal, a foil-wrapped kitchen door — steam attacks the adhesive rather than the soil. Its claim to sanitise is a separate question from its claim to clean: any thermal effect depends on the surface reaching and holding a temperature for a period, which a moving head does not guarantee.
