Microwaves are equipment that has replaced many household appliances: oven, dryer, gas stove and even a kettle. In it, you can cook a variety of dishes from simple scrambled eggs to multi-component pilaf, dry herbs and fruits, warm food to a comfortable temperature, make baked goods, warm a glass of tea or coffee, defrost foods and even burn ceramics. The advantages of its use are many: the process of cooking or heating takes only a few minutes, the dishes are low-calorie, little energy is spent.
The microwave oven needs careful handling and thorough care. During its operation, steam is released, which is deposited on the walls in the form of condensate.
If it is not removed on time, then rust will appear under its influence, the microwave will become worthless.
Of course, the easiest way to throw away a working device or use it as a locker in a garage. But, with a little effort, you can restore the appearance of the microwave oven from corrosion and thereby preserve its functional properties.
Rusted microwave inside - what to do
If the owner of the microwave equipment did not overlook and found traces of corrosion in the manifestation of slight or significant inside the chamber, he should de-energize it, wash it with detergent, dry it and take up repairs. If the damage is small, the recovery process will be simple.
Procedure:
- We clean the chipped places and rust with coarse sandpaper.
- We remove garbage and dust with a vacuum cleaner.
- We process the surface with a fine-grained sandpaper.
- Degrease the metal with a solvent, white spirit is fine.
- We prime the surface so as to repeat the bottom relief with primers GF-021, GF-0119, FL-03K, PF-0244.
- Align with alkyd putty (in the presence of depressions or potholes).
- We walk thin emery.
- Let it dry completely.
- We seal the holes inside the chamber with masking tape.
- We apply enamel in 2, preferably 3 layers, using a foam swab, brush, mini-roller, paint can.
- We dry each layer for at least 20-24 hours at a temperature of +20 degrees.
- Work is best done outdoors.
In the event that not just a dent from a rust was formed inside the microwave, but a hole, it can be repaired at home using a piece of gauze and glue with a two-component composition.
It should be noted on the features of the components used: they must be non-toxic and heat resistant.
Dyes are best used to protect and prevent corrosion such:
- food organic;
- conductive;
- acrylic aerosol.
After drying, the microwave looks, if not as new, then as it is ready for safe and efficient operation.
What are the causes and consequences of using a rusty device
Microwaves inside a microwave oven act on water molecules, acquiring them, thereby raising the temperature. Therefore, a moist aggressive environment appears after each use of the microwave, in the form of drops of water, food debris, fat. Cracks appear on the walls due to lack of care or due to too thorough care using abrasive products.
Subsequently, rust appears in the places of damage.
There are many myths around this technical device. One of them is that rust under the influence of microwaves emits harmful compounds, and the absence of paint makes waves dangerous.
In fact, if a small layer of enamel collapses and corrosion occurs, simply the thermal conductivity will decrease, and the food will cook and warm longer than usual.
But if you continue to use the microwave oven, corrosion will destroy the device, foci of unprotected metal will appear. But metal cannot be used in this equipment because it does not have the properties necessary for the action of microwave waves: it does not have water and its molecules are not accelerated by the waves, but it has electrical conductivity. Waves that are not able to act on the iron return to the emitter, causing a sharp overheating of the mechanism.
As a result, the metal may spark, crack, cause a short circuit and a serious explosion.
The main cause of damage is poor device care.
If you cook and heat food in a special bowl and after each use wipe it with a dry cloth - the stove will last uninterruptedly for many years
Allowed damage - do not immediately get rid of a faithful assistant. As soon as you find that the microwave oven is rusted, take a little time to repair it in order to extend the life and protect your loved ones from the negative consequences of using a rusty device.
