In addition, the heating time is also very important. Under normal circumstances, tableware can be disinfected by rotating 1-3 minutes under fire. Clean kitchen rags only need to be heated in the microwave oven for 1-2 minutes; The mask and towel should be heated for 3-4 minutes. After these articles are sterilized by microwave oven, it is better to wash them with clean water again.
China Household Textile Industry Association has done an experiment, put the towel in a special fresh-keeping box for microwave oven and turn the fire for 3 to 5 minutes. The test found that the towel colony killing rate reached 98%. Boiling the towel in boiling water for 5 minutes can only kill the propagule of general bacteria. The towel is steamed in an autoclave, and the temperature toxicity reaches 120- 150℃. Disinfection 100% takes 10- 15 minutes.
