Carpet Prespray Chemicals
Presprays are typically comprised of surfactants and solvents and do the heavy lifting of carpet cleaning. Carpet pre sprays are sprayed on, then rinsed off capret, generally with a hot-water carpet extractor.
Ensure that you select a prespray based on the level of carpet soiling and the type of carpet; pre-sprays are formulated for either light or heavier soiling, different types of environments (a restaurant vs. an office, for example), and to work more specifically on different types of carpet (wool vs. nylon, etc.).
Once sprayed on, cleaning process is often assisted by light agitation. For best results use a soft brush, carpet grooming rake or cylindrical brush machine.
Always follow individual product instructions and some presprays require a longer soak time, however do not leave to dry. If product has dried in carpet, do not respray. Use carpet extractor to remove and then respray if necessary.
