Vacuum the carpet to remove loose soil, dust and dirt before starting any cleaning process. If you skip this step then it may just be pushing your mess deeper into the fibers of whatever surface we are working on! Make sure that stains like oil or tar will require special treatment as well - consult a stain removal chart for what kind(s)of cleaner is right for those types-of messes (or visit our blog post!).
To keep your carpets looking like new, you need to clean them often. If using a vacuum isn't convenient or possible for whatever reason—an old-fashioned brooms are great alternatives that will get rid of all those pesky particles quickly!
