This is where the Berber carpet tiles show why they are so convenient. Their main benefit is that if you get a really difficult stain on it and you have to bring it to a professional cleaner, you can easily remove only the stained tile without touching any of the other tiles. This way you don't have to move any furniture and you have no problem with delivery of the tile, as it is relatively small.
But before you put your Berber carpet tiles to a professional cleaner you will probably try to clean it by yourself. The cleaning process depends on what your tiles are made from. Berber carpet tiles made from olefin can be cleaned by steam cleaning. The problem is that the cleaning solution usually slides down the shaft of the fiber because it does not get absorbed by the carpet. This causes the tiles made from olefin to dry for a long time.
Berber carpet tiles from nylon are best cleaned with water-based solution. It is partially absorbed into the fibers, while the rest of the solution goes to the bottom. But still the drying time is considerably shorter than it is the case with olefin fibers.
Berber carpet tiles made from wool are suprisingly resistant to crushing, staining and dirt. They are best cleaned by some dry method of cleaning. You just have to be careful to ensure the pH level of the cleaning solution is neutral. A high level of pH solution that you apply on the carpet will ruin the wool carpeting over time.
