Stain guards are an important step in maintaining carpets. Carpet protectants serve multiple purposes. First, they help restore the original factory stain resistance. So when something is spilled or tracked on your carpets it can be more easily removed without causing permanent staining or discoloration. Secondly, it helps reduce wear by creating a barrier between the fibers and dry soiling which can scratch and damage fibers. Lastly, it helps to keep carpets cleaner for longer by allowing for more effective vacuuming and spot removal.
