Some carpets may turn brown after cleaning. One of two problems may exist: if the carpet was steamed cleaned and was really soiled, then deep embedded soil will migrate to the surface of the carpet during drying. In most cases the cleaner likely did not prevacuum the carpet and could also have overwet it. If this is the case, then the problem is easily solved by recleaning. An example of a before and after recleaning is shown below.
