How many seconds are required to keep iodine and quarts on the table for effective sanitization?

  1. 15 seconds

  2. 20 seconds

  3. 30 seconds

  4. 45 seconds

The correct answer is: 30 seconds

Iodine and quats require 30 seconds of contact time to effectively sanitize surfaces. This contact time allows the chemical to fully eliminate any harmful bacteria or germs present on the surface. Shortening the contact time could result in inadequate sanitation, while extending it may not provide any additional benefits in terms of effectiveness.
