The preferred temperature for washing equipment submerged in water is 140°F. This temperature is effective for several reasons. It is hot enough to kill many pathogens, including aquatic invasive species (AIS), bacteria, and other microorganisms that could potentially harm local ecosystems and water sources. Additionally, washing equipment at this temperature helps dissolve oils, fats, and other materials that may cling to the surfaces of the equipment.

Higher temperatures, such as 160°F, while even more effective in killing pathogens, may not be practical or safe for all types of equipment. Some materials could be damaged or degraded at such high temperatures, which could limit the effectiveness and lifespan of the equipment. Therefore, 140°F strikes a balance between achieving effectiveness in sanitation while minimizing the risk of damaging the equipment.

In summary, washing at 140°F is the optimal temperature for effectively removing potential contaminants while ensuring the integrity of the equipment remains intact.
