Let’s start with a clean slate (floor)
and dismiss any notions that natural stone care and maintenance is too time consuming…
Watch a video from DuPont™ StoneTech® Professional about cleaning natural stone.
This company produces specialty neutral pH formula cleaners. I often recommend this excellent (non-affiliated) website to my customers who have concerns regarding the upkeep of slate.
As is stated at the end of the video, don’t forget to seal all natural stone. Sealing is absolutely essential to ensure that stone stays in tiptop condition. Please note that it is always a good idea to buy sealers from a company that produces compatible cleaning products (many commercially available cleaners are too powerful for use on natural stone).
