Recurring Stain

This is a common problem especially when you combine lack of experience with a berber carpet. For the sake of this argument I am going to assume that you are dealing with a synthetic (probably olefin)

The real key to cleaning a berber is to be in control of your drying! There are several ways you can accomplsh this.

1. Make vacuum passes in both directions to account for the differences in pile height.

2. Employ the use of blowers / fans or whatever else you can move larger amounts of air with. This will cause the carpet to dry faster.

3. After extraction cleaning, go over the area with a rotary machine and dry bonnet. This will absorb the excess moisture and once again decrease the dry time

i am sure others may have other suggestions but just make sure you dry the carpet as fast as you can!. Hope this helps

Jim is right on the money. Most berber carpets are made of olefin fiber. Olefin holds almost no moisture, in other words the cleaning solution accumulates at the base of the fiber after multiple passes, the solution then mixes with the left over stain or dirt at the base of the fiber and through the drying process wicks back up to the top of the fibers and shows as a stain.

Reclean and then use  the technique Jim described. After all Jim is Mr. Industry Guru.
