1. Steam
This method can be used successfully only in confined areas. All parts of equipment must be
exposed to a temperature of at least 170°F for at least 5 minutes.
2. Hot Water
This method is difficult to use on assembled equipment, particularly where hot water flows
over a surface cooler. The temperature and exposure time is the same as steam.
3. Chemical
An approved chemical sanitizing solution, such as chlorine (not household bleach) or
quaternary ammonia is circulated or pumped through assembled equipment. Equipment may
also be dipped in a solution to expose all the surfaces to the sanitizer. The strength of a
chlorine solution should be 100 parts per million (ppm) for 30 seconds of contact time or 50
ppm for 2 minutes contact time.
