Pre spray helps break up and loosen stains, oil, and heavy soil that is hiding deep inside carpet fibers. This allows you to use less water and soap during the shampooing process. It also helps with odor removal and makes the carpet feel soft and fluffy after cleaning.
There are a few different types of carpet cleaning pre spray available on the market. Some are liquids that can be sprayed on the carpet and some come in a powder form that you can sprinkle on the carpet before scrubbing with a broom or brush to get into crevices. Some of these powders can also be used as a spot cleaner.
Some prespray chemicals are formulated for different conditions like light or heavy soiling or for different carpet construction and fiber types. They may contain ingredients like specialized polymers, encapsulating surfactants, sequestrants, and alkaline builders to help break up and dissolve problem soiling and reduce dry time.
