At what point is a sanitized surface no longer sanitized?
An unclean surface cannot be sanitized. Generally, the longer time a sanitizer is in contact with the surface, the more effective. Sanitized surfaces should air-dry. Chemical sanitizers become more corrosive at temperatures greater than 130°F.
How hot should water be to disinfect?
Water temperature must be at least 180°F, but not greater than 200°F. At temperatures greater than 200°F, water vaporizes into steam before sanitization can occur. It is important to note that the surface temperature of the object being sanitized must be at 160°F for a long enough time to kill the bacteria.
Does heat sanitize?
Sanitizing may be accomplished manually or with equipment such as dishmachines using heat (as steam or hot water) or chemicals. When heat sanitizing, using a higher temperature generally shortens the time required to kill bacteria.
Does the dryer kill bacteria?
A dryer can potentially kill the vast majority of germs if it gets hot enough. 135°F is the minimum temperature at which a dryer can significantly reduce the number of bacteria and viruses on your clothes. However, much depends on the length of the drying cycle, the fabrics and the species of bacteria (and virus).
