Berber Carpet Cleaning
Berber carpet is the name associated with carpets with a loop construction. Traditional Berber has a more specific definition, but these days, if it has a continuous loop it is referred to as a Berber carpet. It can be made of just about any material but it is most commonly made of either olefin/polypropylene or nylon. Because of the tight loop construction, it does have some special cleaning requirements.
Because of the loop construction, this type of carpet can be tough to thoroughly clean. The construction causes a textured pattern which makes it tricky for the cleaner to reach all of the carpet fiber. This is true with all methods but it is particularly true with steam cleaning where the carpet wand may have trouble staying in contact with the surface of the carpet. To combat this problem, your carpet cleaner should take more time when cleaning this type of carpet so that they reach the entire surface. If using a steam cleaning method, your carpet cleaner should make an extra drying pass to remove additional moisture that may have been missed if the carpet wand lost contact with the surface.
Another problem that is common with Berber carpet is wicking. Wicking can occur when the carpet takes too long to dry and soil from below the carpet wicks back up to the surface. This is a problem with all Berbers but is particularly bad with olefin or polypropylene Berber carpets. This is because this type of material absorbs little moisture causing water to flow down the fiber to the backing of the carpet. To combat wicking problems, your carpet cleaner should get the carpet dry as fast as possible. This might involve the use of carpet fans, ceiling fans, the homes HVAC system or a combination of methods.
The last problem that I will discuss with Berber is the possibility of runs in the carpet. Because of the continuous loop, it is possible to pull a fiber and cause a run that goes across the entire surface of the carpet from one end to another. To combat this problem, loose ends should be snipped when possible and care should be taken hen vacuuming the carpet or when using rotary and crb (counter rotating brush) machines.
