    micro‐organisms.

    • Practical definition:

    Physical action with detergent giving the removal of organic material and

    99‐99.9% of organisms present.

    Chemical Action

    •Soils are electro‐chemically bonded to thesurface. We must break that bond to removethe soils

    •Cleaning “happens” at Neutral pH (pH = 7)

    12/72

    Cleaning With Chemistry

    1‐ Identify the relative pH of the soil

    2‐ Apply a product with the opposite pH

    3‐ Wait for some time for the chemistry towork
