How to clean cork floors<br>Sweep regularly. Use a soft-bristled broom, a dust mop, or a vacuum cleaner with a soft brush attachment. Depending on how heavily you use the area, repeat 2-7 times a week, or whenever you notice it getting dusty.
If you never use the area, it will be enough with a couple of times a week
My statement is correct because it says depending on how much you use the area, clean 2-7 times a week. If you rarely use it, 2, the minimum, will be enough for its cleaning. I think it was difficult for the system due the use of "Couple" instead of "2"
