In Hong Kong, many people enjoy dining out. Aside from taste and ingredients, have you ever noticed waiters clearing used dishes or handling cash, then serving food without washing hands?

Most workers understand hygiene standards, but due to workflow and efficiency, frequent handwashing is not always practical.

Rapid Cleanse provides fast, minimally disruptive hand hygiene. Its key components include front nozzles for food-safe alcohol spray, rear fans air curtain and dryer, LiDAR sensors for hand detection, and a hydrophobic-coated glass base.
