Interim cleaning is a term used to describe the process of “quick” appearance cleans between deep cleans. For example, if you normally deep clean twice per year but sustain enough coffee spills or foot traffic to warrant more cleanings, you can prescribe monthly or quarterly interim cleans that only address the high traffic areas and keep the appearance level acceptable. This will keep the carpet looking great throughout the year. It also becomes much easier to clean when its “deep” cleaning time. This process also extends the life of the carpet by removing the dry soil more often. Since it is considered a lighter clean, the most widely used method to accomplish this is with an encapsulation solution such as Encapsulating Prespray.
