This is a question I have heard too many times to count.  My answer would be, at least once a week, if not
more!  Alright, back to reality. To answer this question without prejudice I will simply quote what your carpet
manufacturer has to say. After all, they did make your carpet and are the ones responsible for the warranty.

Shaw is the largest manufacturer of residential carpet in the world.
Periodic professional cleaning of the overall carpet is required. The frequency of overall cleaning may vary
depending on the level and type of traffic and the conditions to which your carpet is exposed. This may range
from as little as 6 months to 24 months between cleanings. Your carpet must be properly cleaned at least once
every 24 months to maintain your warranty.

Shaw recommends only Hot Water Extraction utilizing carpet cleaning products, equipment, and systems
certified through the Carpet and Rug Institute’s Seal of Approval Program. These products are listed at www. Warning: Non-Approved cleaning products and topical treatments, applied by you or by a
professional carpet cleaner, will void your warranty.

Shaw residential warranties require that professional service be performed by an IICRC Certified Firm.  We
recommend  Dave Steely, Maximum Carpet Cleaning in Concord. As we believe he works harder and does a
far superior job than any other carpet cleaning company we have ever worked with.  Well, that might not be
written in their warranty but it should be.

Now you know.  I wish I could educate everyone on the proper care and maintenance of their carpet, but for
now I will have to settle for my clients only.  I have often said that if people knew the proper steps to maintain
their carpet, most would follow them.  Unfortunately most people do not. Even when you purchase new
carpet you can get wrong information from your salesperson.  The one key thing to remember, when in doubt
Contact Me.  You can always email, or call me with any questions or concerns regarding your carpets.  

I will be happy to answer them.
I can even help when you are purchasing new carpet.  

By working together to maintain your textiles we both win.
Proper maintenance is the key to longevity.
