A foam trigger sprayer is a relatively inexpensive addition to a cleaning arsenal. When sprayed directly on the surface or right inside a porous material like carpet or upholstery, the foam expands and forms an aggressive barrier against any dirt or liquid that might penetrate the substance. These sprays are designed for use on the floor, but can also be used on bare floors or even garage floors to clean out debris and protect the area from future dirt or liquid spills. The foam itself expands because it contains a special kind of chemical called a "foamoid".

These kinds of chemicals react with the physical properties of the substance being cleansed, and the foamoid will either harden or break down depending upon the properties of the substance being cleansed. A regular spray bottle is sufficient, as the foam will adhere to the nozzle if the pressure is applied properly, but you may need to use a power washer to properly clean bare floors or garage floors, especially if there is dirt or liquid involved. For these surfaces, a power sprayer or foam gun can be used. In either case, it is important to make sure that the nozzle is not too close to the surface - the last thing you want is to get the foam too close to the surface and create a reaction with the substance contained in it.

Foam trigger sprayers are widely available and are fairly easy to use. They are designed to spray at a low pressure, and have an adjustable spray pattern so that they can be used effectively on a variety of different surfaces. If you have trouble locating one locally, or would rather have your foam trigger sprayer delivered to your home, there are a number of companies who specialize in delivering small quantities of these chemicals to homes and businesses on a regular basis. You can find them by looking in your local phone book under "foam products" or by searching online for the name of the foam trigger sprayer company.
