Which of the following is commonly used as a fabric protector in upholstery cleaning?

The use of Teflon or similar polymer-based coatings as a fabric protector in upholstery cleaning is well-established due to their ability to repel stains and liquids effectively. These coatings create a protective barrier on the fabric surface, which minimizes the absorption of spills and makes it easier to clean. Teflon, in particular, enhances the longevity of upholstery by providing resistance against dirt, oil, and water, thus maintaining the appearance and integrity of the fabric over time.

In contrast, silicone spray is often used as a water repellent but may not provide the same level of protection against stains as polymer-based coatings. Polyvinyl chloride (PVC) is a synthetic material used primarily in manufacturing different products rather than as a fabric protector for upholstery. Cotton-based sprays may not offer the same level of synthetic protection and often lack the stain-repelling properties needed for upholstery maintenance. This makes the selection of Teflon or similar polymers the most effective choice for fabric protection in this context.
