Here we use the Dupray Hill Super Inox with the lance and the nylon brush. Put the steam cleaner on the highest setting and gently brush all along the sink. The steam will release all the trapped dirt in seconds. Use a cloth to wipe off the residues released by the high temperatures of the steam and your surface will shine like new. Steam cleaning is the most efficient and definitely the quickest way to disinfect all the surfaces in your bathroom.
