This video is from way back but the information is still true today.
  1. You should wait as long as possible before cleaning your carpet. No. Dirt is abrasive- like sandpaper. Every time you step on your carpet, you grind dirt into the fibres. This cuts your carpet, just as if you had used a knife. This cutting causes your carpet to wear out faster. A dirty carpet will not last as long as a clean carpet. And while vacuuming helps -by itself, it’s simply not enough. The longer you wait to have your carpet cleaned, the more damage you do to your carpet and the faster it wears out.
  2. The only reason to clean a carpet is to remove dirt. No. As you are probably aware, outdoor air contains pollens, fungus, bacteria, air pollution, cigarette smoke, car exhaust- and hundreds of other chemicals. When you come into the home, you carry those pollens, bacteria etc. in your hair and on your skin, clothes and shoes. Not surprisingly all those chemicals and toxins wind up in your carpets. If you have allergies or breathing problems the source could be in your carpets.
  3. One method of carpet cleaning is as good as another. No. The dry cleaning methods- which are dry foam, dry chemicals, and dry compound- do not rinse your carpet in any way. Instead, they leave dirty residue. You may say they clean the carpet half way. The most effective method is hot water extraction. Hot water extraction means hot water cleaning solution, under high pressure, is forced into your carpet and then sucked out of your carpet. Shaw industries, the world’s largest carpet manufacturer, recommends hot water extraction as the primary method of cleaning carpets, along with professional cleaners like myself that is certified by City & Guilds just like your other trades.
  4. Having the right equipment is all a company needs to clean your carpets properly. Not true. Many companies own hot-water cleaners but very few companies teach their employees how to use them properly. This is why it is important that you choose your carpet cleaner very carefully. The best cleaning companies are those that have been certified Before you choose a carpet cleaner, ask to see written proof of certification and also the certification of the technician who is going to do the job! If they don’t have them -don’t use them!
  5. The company that offers the lowest price is the company you should hire. No. I’ve seen so many problems arise from lowest-bid companies that I suggest you NEVER hire a company that quotes the cheapest price. The two most problems are: a, The price may not be for the services you want performed. The company may be equipped to remove only the dirt from your carpet. But you may want bacteria, fungus, pollens, dust mites and tobacco residues removed as well. b, The price you see advertised may not be the price you pay. Many homeowners have learned that the low price they saw advertised only lasted until the carpet cleaner got into their home. Then they were pressured into paying a lot more for a variety of add-ons. (Some carpet cleaners even break the law by using illegal bait and switch tactics.)
  6. Any honest carpet cleaning company should be able to give you an exact price quote over the telephone. I wish this were true but it isn’t. Honest, reputable carpet cleaning companies almost never price carpet cleaning by the room. Instead, carpet cleaning is usually priced by the square foot. So if you’d like me to tell you the exact cost of cleaning your carpet, I need to know the exact number of square feet that you want cleaned. To get an accurate measurement, I use a digital estimator to measure the size of the carpet area. First, the type of carpet. Certain types of carpet are harder to clean than others. Second, the amount of soiling. Carpet that hasn’t been cleaned for ten years will take longer than a carpet that we cleaned within the last year. Third, the amount of furniture we have to move. If you move your furniture, you’ll save money.
