Encapsulation: Some people refer to this as ‘dry cleaning’ so ask your technician to clarify between Encapsulation and Bonnet Cleaning. Encapsulation uses a similar machine to Bonnet Cleaning but it is called a Cimex. In this process the machine serves in the same way as Bonnet Cleaning, where it agitates the floor to remove stains. The key difference with this process is the chemical being used. In this process once the chemical has been applied it will encapsulate any dirt and stains, then crystalizes and set in tiny little microscopic balls. Just picture a tiny little bubble with something in the middle of it. Then once dried you go over the carpet with a vacuum cleaner and it sucks up all the crystalized dirt and stains. The chemical solution being used is silicon based which coats the fibres for easy removal when vacuumed. When done correctly this is an excellent maintenance carpet cleaning technique.
Hot Water Extraction/Steam Cleaning: Steam Cleaning and Hot Water Extraction are virtually the same thing. In actual fact, steam cleaning does not use steam at all. The process uses hot water applied at low pressure. In this method of carpet cleaning the carpet technician sprays on a chemical solution over all carpeted areas. The solution is left to dwell for a short period of time, then using a wand, the technician uses low pressure to spray onto the carpet, this agitates and rinses the chemical and carpet. Finally, a large extraction machine with two, three stage vacuum motors, suck all the dirt and chemicals from the carpet. This system by far achieves the best result. I recommend using this process in conjunction with Encapsulation to maintain your carpets.
