    • 95 Very Good (less then ten cfus present)
    • 90 Good (10-25 cfus present)
    • 85 Satisfactory (25-250 cfus present)
    • 0 Failure (>250 cfus or intestinal or skin group bacteria present)
  2. pH: we rate the pH colorimetrically
  3. Absorbency: we test the test piece to ensure excess detergent is not used
