What does the score mean?

A score greater than zero means the test wash may be a better choice than your facility's regular wash, a score of zero indicates that the test wash is approximately the same, and a score of less than zero indicates that the test wash may not be a better choice for your facility.

If the test wash appears to be approximately the same as your normal wash overall, look at each individual category. Which is most important to you? Different scores in that category may still help you decide which blanket wash is best for your shop.
