Avoid using ordinary plastic containers: first, hot food will deform plastic containers, and second, ordinary plastics will release toxic substances, pollute food and endanger human health.

Avoid using closed containers: when heating liquid, use wide-mouth containers, because the heat generated by food heating in closed containers is not easy to dissipate, which makes the pressure in the containers too high and easily leads to blasting accidents.

Avoid using metal utensils: because these utensils are iron, aluminum, stainless steel, enamel, etc. When put into the furnace, the microwave oven will generate electric sparks when heated, reflecting microwaves, which will not only damage the furnace body, but also heat food.

It is not allowed to put anhydrous food into the microwave oven to make it work, which will lead to the damage of the microwave oven.
