Clean: food safety starts here!

Clean and sanitize sink and counter tops

  1. Wash counter tops and prep sinks with hot soapy water. Rinse off soap with clean water.
  2. Sanitizer Solution: Fill squirt bottle with 1 quart water. Add 1 teaspoon of chlorine bleach; or fill squirt bottle with full-strength white vinegar or hydrogen peroxide; or use commercially prepared sanitizer per directions on label.
  3. Spray counter tops and sink with sanitizer solution. Let air dry for 10 minutes.
  4. Wash hands.

Wash hands for 20 seconds

  1. Wet hands under hot running water. Add lots of soap.
  2. Rub and wash back of hands, wrists, between fingers and under fingernails for 20 seconds.

Clean as you go
