What does the hot water extraction method inject into the fabric?

The hot water extraction method is a widely used cleaning technique for fabrics and upholstery. In this process, a mixture of hot water and a cleaning solution is injected into the fabric. The high temperature of the water helps to loosen dirt and grime, while the cleaning solution enhances the cleaning action by breaking down contaminants, oils, and stains. This combination works effectively to clean and refresh the fabric, ensuring that dirt and debris are more easily extracted.

The other options do not accurately represent what is injected during the hot water extraction process. Cold water would not be effective in loosening dirt and stains as well as hot water. An aerosol cleaner typically comes in a spray form and does not penetrate the fabric in the same way as hot water extraction. Pure solvent, while it can clean certain materials, does not provide the same thorough method of deep cleaning as the combination of hot water and a cleaning solution used in this technique.
