We used to service a chain of Sweet Tomatoes restaurants. At first we performed HWE. Occasionally there would be a complaint but overall they were satisfied. Then we switched over to straight encap. Initially, I figured we may still need to do some HWE every once in a while. But in fact, we were able to continue to provide excellent results without needing any HWE. Monthly encap alone kept this restaurant chain happier than when we were cleaning with HWE. No more wicking. A good encap program was capable of keeping the carpet looking great!
