Of all the carpets a cleaning technician will encounter, the most difficult will most likely be restaurant carpet. Cooking greases that are tracked from the kitchen and airborne grease can literally coat everything in a fine layer of oil, which attracts and holds on to dirt, dust, and particulate soils.
Many restaurants are extremely tight with their carpet cleaning budget. Restaurant owners and managers know that a new group of cleaners are knocking on their door and will give their services away for practically nothing to try and get the job. This leads to a series of cleanings that leaves residue in the carpet, which causes rapid resoiling.
In order to perform the best job, a technician must follow the “cleaning pie” as taught in the IICRC CCT/CCMT classes.
The cleaning pie consists of four parts:
Time, Agitation, Chemical, and Temperature.
When one part of the pie is decreased, one or more of the others must be increased. For example, if your cleaning solution isn’t hot enough, the lack of heat means you’ll need to use a stronger chemical, allow more dwell time, or apply more agitation to get the same cleaning results.
After a thorough vacuuming, the carpet should be pre-sprayed with a chemical designed for restaurants (usually a high pH and containing enzymes). The pre-spray should be agitated with a brushing system to penetrate the grease and then given adequate dwell time (ideally 10-20 minutes). Thorough hot water extraction containing a good alkaline detergent will suspend and rinse the soil from the carpet.
On carpet that has great amounts of residue, or if the carpet is a printed nylon, it would be a good idea to use an acid rinse, such as Matrix All Fiber Rinse, to neutralize the excess leftover alkalinity from previous cleanings. The acid rinse prevents any type of potential bleeding and will brighten the color in a printed carpet.
The use of air movers will greatly decrease the drying time and allow foot traffic on the carpet sooner. The use of a cotton bonnet will also decrease drying time as well as remove wicking soils.
Be sure to clean the walk-off mats that are used as transition mats from the kitchen tile to the carpet (or by the salad bars) as these tend to be coated with grease that will get tracked back on to the clean carpet.
Once the carpet has been restored by hot water extraction, an encapsulation system can be incorporated on a monthly basis. This interim cleaning method can save the budget and keep the carpet in a continuous high state of appearance.
