Limestone is a very long-lasting stone. It requires more maintenance than granite or marble, but some believe it gives their homes a more classical look than other stones. Limestone is a porous mineral and can accumulate dirt over time. With proper maintenance, however, you can keep your limestone looking new for years. Limestone is not recommended for high-traffic areas in your home due to its softer nature and its tendency to scratch more easily.
Remove loose particles of dirt by vacuuming, using a dust mop or sweeping the surface of the limestone.
Attach the large brush attachment to the vapour cleaner. Also attach a towel on the front clips only.
Turn on the vapour cleaner. Use the large brush attachment to clean the entire surface. Flip the towel under the brush and go over a second time to finish the wipe.
Remove the large brush and towel and attach the nozzle brush.
Clean the grout with the nozzle brush. Draw the brush across the grout slowly to allow the steam to loosen the dirt.
Wipe away the loosened dirt with a towel.
