The best method for cleaning and sanitizing equipment that cannot be placed in a dish machine or three compartment sink would be using a chemical sanitizing solution. This method involves using a solution of water and a chemical sanitizer, such as chlorine or quaternary ammonium compounds (QUATS), to clean and sanitize the equipment. The equipment should be scrubbed and rinsed thoroughly before being submerged in the sanitizing solution for the appropriate amount of time as per the chemical sanitizer's instructions. The equipment should then be rinsed with clean water and air-dried or dried with a clean cloth.
