Bonnet cleaning, also called spin pad or absorbent pad or carbonated shampoo cleaning, is simply an adaptation of hard floor spray buffing to carpets. Even though it is not true "dry cleaning", many people using this system call it dry cleaning, which is highly deceptive. There are two methods of application of the cleaning solution: The rotating absorbent pad (usually cotton or rayon) is then attached to a low speed (175 RPM) Rotary Floor Machines – with a heavy-duty motor because of the high friction involved. A special drive block is required to keep the bonnet or pad from slipping off. Dirt is theoretically collected into the pad. The pad is supposed to be changed or turned when the pad surface stops absorbing soil – this is usually up to 600 square feet per pad side. The pad is then washed out and reused as needed. Sometimes, carbonated water is used to (in theory) give better soil suspension and bring down the pH. Nearly all carpet and fiber manufacturers recommend against using this method on Cut Pile carpet. Additionally, many of the detergents and shampoos for bonnet cleaning contain high levels of optical brightener. The advantages of this cleaning method are: low equipment cost, rapid drying (usually dry in 30 minutes), very rapid cleaning (because you're only cleaning the surface), and the ability to charge less because it’s quicker. The disadvantages of this cleaning method are: pile distortion and fiber damage on cut-pile carpet, swirl marks left behind, soil ground into the carpet, detergent and soil build-up. Additionally, only two dimensions (width and length) of the carpet are really cleaned – that is, the surface. Under the cleaned surface may exist a living, breathing sewer. Unfortunately, a clean "appearance" is all some customers care about. Also, a large inventory of clean bonnets is required as well as the washers and dryers to clean the bonnets. Here are two mill and fiber producer statements on bonnet cleaning "Bonnet or Absorbent Pad … The use of this method is not recommended on cut-pile carpet." Bonnet cleaning does have a place in the scheme of things – sometimes it helps after extraction cleaning an area of Loop Pile with a large number of spills. For example, if you have been extraction cleaning a level-loop pile carpet in a dining room in a nursing home where there is a large number of large spills and many of the stains always reappear, using dry bonnets after cleaning will reduce drying time and reduce possibility of wicking and, therefore, reduce the likelihood of having to go back. If you see a large stain indicating a massive spill, even this won't totally solve the problem. Of course, if there are just a few areas or if this is cut-pile carpet, you can simply spray down ARA anti-resoiling agent after extraction cleaning on the spill areas to reduce wicking. For those who do bonnet clean level loop commercial carpet, we do have available Non-Residual Roto-Brite II, Soil Retardant Roto-Brite and Pro’s Choice Brush & Bonnet. Clean and Brighten Your Cotton Bonnets: When you wash bonnets, use 3 oz. (1 heaping scoop) of Extreme Clean with 6 oz. (2 heaping scoops) of OSR in your wash. NOTE: Do not run a DRY bonnet on olefin (polypropylene) carpet or rug - olefin has a very low softening point! Related Products:
