I am not sure exactly what can distinguish a good cleaner from a bad cleaner. I suppose starch levels? Getting stains out? I guess the best cleaner is like the the best referee... you don't notice them.
I cannot think of a time when I came across any issues with this cleaners. They do a very professional job every time I bring something in. The only down side is it is very difficult to find a parking spot nearby. If you have someone to run and drop it off, I highly recommend using this cleaning service. Like I said, never an issue.
