These videos of commercial carpet cleaning are oddly satisfying. I work for Chem-Dry of Tampa FL and we clean dirty commercial carpets on a regular basis. I'm always surprised how much soil is layered up on restaurant carpets. Every time I'm cleaning a restaurant I can't help but think that this is an area where people come to eat and the floor is so dirty. There is no one to blame the restaurant is doing everything it can to keep up with the carpet but with that much traffic it's just going to get dirty. There are some restaurants that we clean every 3 months and even those are difficult to stay on top of.
In the commercial carpet cleaning video above they are using heat and pressure to clean the carpet. From looking at it my guess is that they are cleaning the carpet at 400 psi and 280 degrees of heat. That much pressure and heat will easily remove heavy soil build up.
At Chem-Dry of Tampa FL we use much lower pressure and heat, about 100 psi and 180 degrees of heat. We get the same results with less moisture because our commercial carpet cleaning solution is carbonated. Millions of bubbles remove the soil in the carpet without soaking it. It's highly effective and much easier on the carpet. Pressure and heat takes it's toll on carpet, breaking down adhesives and damaging fibers. On top of that a lot of moisture can easily wick soil from under the carpet making dirty again in much shorter time frame. Try Chem-Dry of Tampa FL for your commercial carpet cleaning. You wont be disappointed.
