The level of dirt and stains really come to show when you have a carpet thats bright in color. Having a bright colored carpet will lead to cleaning the carpet more frequently. In turn, this can prove to be helpful when trying to determine when it’s the right time to have deep cleaning done. You may not know this but some carpet manufacturers have a warranty. This requires you to actually follow a certain type of level of cleaning to retain that warranty. Meaning vacuuming often and getting deep cleanings done once or twice annually. Keep the deep cleanings documented as well to show as proof that your upkeep is in fact being accomplished just in case an issue is to arise and you need to use your warranty.
