How do I clean a dirty lacquered floor?

We recommend using soap specially developed for such floors.

If it is very dirty, we recommend using a heavy-duty cleaning product to strip the surface. Then wipe the floor with a damp mop  and apply a matt or satin renovator lacquer to restore the surface.

Brushed floors (i.e. all oak finishes except Satin), should then be cleaned with a soft nylon brush, working with the grain.
