After the microwave oven has been used for many years, a thick layer of grease has accumulated on the inner wall, which is difficult to clean, and it is neither beautiful nor hygienic.

How to clean the microwave oven becomes an important issue for every family.

As we all know, the working principle of the microwave oven is to accelerate the movement of water molecules in the food by reflecting the microwave oven on the inner wall and penetrating the food, thereby heating the food, and once the inner wall of the microwave oven is dirty, it will inevitably affect the heating efficiency.

The microwave oven is used to heat food, so it must be kept clean at all times, but cleaning the microwave oven is a very troublesome thing.

The microwave oven is not clean, and the growth of bacteria affects health is not good.

Next, I will give you a detailed introduction to the practical cleaning tips, and teach you to easily fix the stains in 10 minutes.

1. Microwave oven cleaning steps

Step 1: Clean the exterior

Disconnect the power, take a cloth or sponge with good water absorption, soak it with warm water, squeeze out the excess water, and wipe the floating dust on the outside of the microwave oven.

Especially at the vents, so as not to affect the normal operation of the microwave oven.

Because the low temperature will splash the burned food, do not use a metal brush to clean it, so as not to scratch the outside of the microwave oven.

Step 2: Soften oil stains

Prepare a bowl of water and add some vinegar. The ratio of water to vinegar is about 4:1. Stir gently, put it in, and heat it for 3 minutes on high heat.

It is beneficial to the softening of oil stains on the inner wall and can also remove the peculiar smell.

Why use vinegar? One is that the vinegar is easy to clean up, and it will fall off once you wipe it. Second, sour vinegar can also play a role in disinfection.

The third is the acidic properties of vinegar to soften food residues.

The amount of vinegar can be up to half, which is a 1:1 ratio with water. But in order to clean and not waste vinegar, just put it in a ratio of 1:4 to play a cleaning role.

Step 3: Wipe inside

Wait 2 minutes until stubborn dirt becomes soft and easy to remove. Then take out the bowl, hob, and collar, wipe the inner wall with a damp cloth first, do not rinse, so as not to let water flow into the circuit in the furnace, and then wipe the water with a dry cloth.

Keep in mind here that steel balls must not be used. The inner wall of the microwave oven and the turntable are coated.

Wiping with steel balls will reduce the service life of the microwave oven.

When scrubbing the bottom of the microwave oven, the turntable should be removed. If the glass turntable and collar are hot, they need to be cooled before disposal.

After cleaning the turntable and the collar, remember to reset it as it is.

Step 4: Clean the cracks in the door

If there are food residues or oil stains remaining on the door hinges and door seams, use a soft brush dipped in some neutral detergent to wipe it, do not wipe it with a strong detergent or scrape with a knife.

Finally, just return the things in various parts to their original positions.
