What is the steam temperature used for cleaning?

• A. 200°F
• B. 180°F
• C. 212°F
• D. 250°F

Answer: (A)

Steam cleaning relies on very hot steam to loosen soils and reduce microbial load on surfaces. About 200°F is used because it’s hot enough to lift grease and soils effectively and to transfer heat quickly as the steam condenses on the surface, helping to sanitize without requiring extreme temperatures. This temperature strikes a balance between cleaning power and safety for equipment and handlers.

Lower temperatures like 180°F don’t provide as much cleaning and sanitizing effect, while 212°F represents boiling steam that isn’t always necessary for routine cleaning and can be harder to maintain consistently in some cleaners. Very high temps like 250°F require specialized equipment and can risk damaging materials or posing greater safety concerns. So, 200°F is the practical, commonly used steam cleaning temperature.
