Answer

Any growth on the Tryptic Soy Agar (amber side) indicates cleaning was not effective.

Any growth on the D/E Neutralizing Agar (purple side) indicates that bacteria survived cleaning. D/E Neutralizing Agar is pH sensitive and any color change from purple to yellow indicates bacterial growth.
