If you enjoy going barefoot, or even if you don't, kick your shoes off at the door. Why remove your shoes? If you have a rough board that needs smoothing, you grab a sheet of sandpaper for the job. Guess what's on the bottom of your shoes? Sand and dirt grind away at the fibers in your carpet, leading to an early death.

Take a closer look at the bottoms of those shoes and you'll find oil, dirt and heaven only knows how many bits of leftover dog deposits. Small wonder why your carpet stubbornly refuses to come clean. Do wear slippers or socks inside. The oil from the bottom of your feet also dirties the carpet.
 
Stains in carpet can be a hassle to remove. Never rub a stain, just blot. Rubbing breaks down the fibers and spreads the stain.
 
Always have your carpets cleaned by a professional.
