Foam encapsulation uses synthetic detergents that are distributed evenly onto the rug to loosen the grime. The foam is left to dry, turning into a powder. Dirt particles in the carpet fibres are encapsulated into the dried detergent as soon as the applied cleaning product dries. After this step, the dried foam along with the trapped dirt is vacuumed or brushed. This method is preferred by homeowners because it doesn’t use a lot of water and doesn’t require additional drying time.

Dry Carpet Cleaning

Compound cleaning, widely known as dry carpet cleaning is the 3rd most popular treatment, recommended for home rugs. It has gained increasing popularity among homeowners and the approval of carpet manufacturers because of its efficient cleaning performance, and convenience as the procedure does not require drying time.
The highlight of dry rug cleaning is the application of the cleaning compound onto the carpet. The powder is rubbed in the fibres using motorised counter-rotating brushes. This helps agitate the carpet fibre and allows the cleaning agent to settle. After this step, the powder is let to sit for a short period of time (depending on the different product) and to loosen the dirt. The last step of this rug cleaning method is extracting the powder along with the grime with a powerful vacuum.
Since the dry rug cleaning technology was introduced in the 1980s, many types of cleaning compounds or powders appeared on the market. As this method is considered relatively new compared to the rest of the conventional carpet cleaning treatments that have been used for decades, many companies and customers question the effectiveness of the procedure.
