Normal cleaning can be taken care of with vacuuming.

A simple damp mopping is a good idea on an occasional basis. But don't use soap, wax or polish since they will leave a film behind, making the floor look greasy period.

Stains can be wiped away easily with a soft cloth and Pergo Cleaner or denaturated alcohol. Do not, however, scrub with steel wool or any other coarse material.

As an added precaution, use felt pads under furniture legs, and pads or plastic wheels under chair legs. Always use a doormat in the front entrance as well.
