Sock fluff traffic lanes

[Act One Cleaning]

Marsonpee, you may be dealing with very fine pet hair, or even carpet fluff that was matted down and now surfacing as you clean. Try a couple of things: vacuum with a beater brush, or use a rubber squeegee to rake at the fuzz. If either technique helps, then keep doing it. If neither helps, use a red pad or a brown pad to damp scrub it again. They have just enough grab to tug that fine stuff out of the carpet nap, but you have to clean the fuzz off the pad every so often.

Remember that hair isn't smooth, it is barbed and can embed itself quite effectively, so be patient. Good luck!
