Carpet Cleaning with Foams
This is a variation of ‘Shampoo’. Foam is generally applied onto the carpet, usually from aerosol containers, and rubbed in with a dry sponge. Once dry, the residue containing suspended soil is simply vacuumed away. Since foam uses little water, there is no danger of over wetting and the connected complications. But due to the same reason, this method is not as effective as the “wetter” methods!
Carpet Cleaning using Bonnet Cleaning
This is another method similar to ‘Shampoo’. Bonnet cleaning employs an absorbent pad (‘bonnet’) attached to the bottom of a rotary machine. Detergent solution is sprayed onto the carpet ad the rotary pad is used to agitate and remove the soil suspended in the solution from the carpet. Once one side of the pad gets soiled, the sides can be reversed. And when both sides get soiled, the pad can be replaced and later cleaned.
This method is used in the regular maintenance of commercial buildings.
Carpet Cleaning with Absorbent Dry Compound
A dry compound containing detergent/solvent is sprinkled onto the carpet and worked into the pile using machines. The soil particles get encapsulated in the absorbent dry compound and are removed by vacuuming. Since this method does not use any “wet” process, there is no danger of over wetting.
