Some companies only do a 1-step process, and just introduce soap with their wand & extract it out in one stroke. But we do a 3-step process: We pre-spray all the carpets which allows the cleaning agent to emulsify and suspend the dirt. Then we do hot water extraction with water that gets to be about 220 degrees or more, to the best of our ability, we rinse that product out so as not to leave a sticky residue. After that, we treat any spots or stains that didn’t come out, rinse again, and lastly we go over everything with a dry stroke to extract as much moisture as possible allowing the carpets to dry quicker and also helps prevent wicking. Doing all these steps takes longer, but we believe it’s worth it because we get much better results!
