Slate, a form of metamorphic rock formed from clay and silt in ancient sea beds, lends a bit of understated elegance to the entryway of your property. Despite its durability, slate — like all natural stone — takes a gentle touch when cleaning to prevent vandalism and scratching. Even when your slate entryway appears clean, wash it at least once every two or three months to prevent grimy buildup that can lead to stains.
Dust the slate using a microfiber fabric or dry mop to remove dust.
Insert a generous squirt of dishwashing liquid to a bucket of warm water. Swirl the detergent and water to create suds.
Dip a soft, white fabric into the soapy water and wring it out.
Wipe the slate using the fabric, rinse the cloth, wring it out and wipe again. Rinse and wring out the cloth frequently to remove all the soap solution.
Eliminate any remaining stains using a one-to-one proportion of hydrogen peroxide and water. Be sure to avoiding washing the grout using the mix. Permit the peroxide option to remain on the stain for 10 minutes before scrubbing using a nylon-bristled brush.
Wipe off the peroxide solution together with the moist, white fabric.
Dry the slate using a soft towel and allow it to air-dry immediately.
Polish the slate using a self-polishing, water-based wax or rub it with a few drops of botanical oil on a soft, dry cloth.
