In dry foam cleaning, what is used to minimize wetting of the fabric?

In dry foam cleaning, the process utilizes foam created from a foaming detergent. This technique is specifically designed to minimize the amount of moisture that penetrates the fabric, safeguarding the upholstery and preventing issues such as mold growth or damage from excessive wetness. The foam itself consists of air bubbles held together by the detergent and acts to encapsulate dirt and grime more efficiently than liquid cleaners.

This method allows for thorough cleaning while keeping the fabric relatively dry, which is particularly important for delicate fabrics that may be sensitive to high moisture levels. Since the foam is applied and then quickly agitated and extracted, it helps lift dirt without saturating the upholstery, thus maintaining its integrity and appearance.

Other options do not serve this purpose effectively. Liquid detergents involve more wetting, as does a water-based cleaner, which can introduce excess moisture to the fabric. Solvent cleaning, while it minimizes water usage, may not be suitable for all types of fabrics, and it typically does not encapsulate dirt as effectively as dry foam.
