A microwave oven is a common kitchen appliance. From homes to hostels, restaurants to offices, this appliance has found its way into almost every kitchen. But have you ever noticed your microwave oven rusting due to constant usage?
You will find rust in the microwave oven, especially in the shared kitchen. The thing is, most people do not know how to clean or maintain it. As a result, the microwave ovens get rusty from the inside.
But that is not the only reason. There are several other reasons for the formation of rust inside microwaves. This article explains why microwave ovens rust inside and how to stop it.
Why Do Microwave Ovens Rust Inside?
Table of Contents,
Here are some common reasons for rusting inside a microwave oven.
Humidity Factor
Moisture is the main cause of rust. When you cook food inside the oven, the moisture inside the food is released and forms condensation on the surface of the oven. This condensation can cause rust to form on the surface.
Improper Maintenance
Have you ever stayed at a hostel? In the hostel, you experience the oven rusting inside. The biggest issues are poor maintenance and carelessness when using the oven. Usually, If you don’t clean the oven regularly, leftover food, grease, and water start to break down. If these substances are not cleaned off of metal surfaces, they will eventually cause the metal to rust.
Metal Type
The type of metal that your oven is made from can also affect how susceptible it is to rusting. For example, cast iron is more likely to rust than stainless steel.
Chemical Reactions
Another factor that can cause rust to form on the surface of your oven is chemical reactions. When certain chemicals come into contact with each other, they can cause a reaction that creates rust.
Age:
The older your oven is, the more likely it is to rust. This is because the metal surface can start to wear down over time, making it more susceptible to rust.
Leaving Food in the Microwave:
You might not think that leaving food in the microwave could cause rust, but it can. When food is left in the microwave, it can start to break down and form rust.
Wrong Cleaning Methods:
You should never use harsh chemicals or abrasive scrubbers to clean the surface of your oven. These can cause the metal to become weak and more susceptible to rust.
How Does Rust Form Inside A Microwave Oven?
Rust forms when iron reacts with oxygen in the presence of water. This reaction is called oxidation. Water speeds the reaction between iron and oxygen, causing oxidation to occur more quickly in moist environments. That’s why you’re more likely to see rust on objects that are kept moist.
How Does Rusting Happen Inside Your Microwave Oven?
Rusting is accelerated by warm temperatures, so when you heat food in your microwave, the water molecules inside the food start to vibrate. These vibrations cause the water molecules to bump into each other and create friction. The friction creates heat, which cooks the food.
But sometimes, these water molecules can also bump into the metal walls of your microwave oven. When this happens, it causes tiny bits of metal to flake off the surface of the oven. These metal flakes can then mix with the water vapors inside the oven and create rust.
Over time, this rust can build up on the walls of your microwave and cause problems. It can make the oven less efficient, and it can also cause the food to taste metallic. Therefore, if you notice rust in your microwave, it’s important to clean it as soon as possible.
