Rust is a common condition that you can see on some of your home appliances; your refrigerator is certainly not an exception.

Though sometimes you may notice it, other times you may be so unlucky to sight this condition.

And even when you discover it in time, feeling so carefree is quite the usual attitude. 

Consequently, ignorance and inability to discover the rust condition can result in its exposure.

In this light, can this exposure cause any harm?

Can the rust in the freezer cause any damage?

Rust in refrigerators is not dangerous or harmful to your normal state of well-being. It’s merely ferric oxide. The groceries or foodstuffs in the freezer cannot absorb the ferric oxide itself. So even though these rusty conditions in your ice chest do not look so pleasant, they aren’t dangerous.

Is A Rusty Refrigerator Dangerous?

Rust will cause no direct harm to you. You merely need to be careful so that the rust(ferric oxide) doesn’t contaminate your food.

The groceries in your freezer can’t absorb this oxide. But if the rust contaminates the foodstuff over a long period, health hazards can break out.

Though rust doesn’t have any adverse effect on our health, we ought to be very cautious.

Avoid any particle of rust in your food, prevention is better than cure, and there’s no crime in being extra careful. 

If you mistakenly or accidentally ingest rust particles, stomach irritation will result.

Aside from the intake of rust particles, inhaling this ferric oxide can attract many health challenges.

Yes, Continuous and persistent inhale of ferric oxide can result in a siderosis condition. Siderosis is a condition that involves the deposition and build-up of iron inside the lungs.

Apart from siderosis, rust also has some connections with an infection called tetanus. Tetanus influences the nervous framework.

But don’t be afraid, don’t panic.

The rust itself doesn’t cause tetanus. Instead, it’s a bacteria found in wastes and soil that causes tetanus.

But note that if the rusty part of the freezer gets any contact with the bacteria that causes tetanus, you’ll be prone to the infection.

I’m just referring to the tetanus infection so that you’ll be more careful while using the rusted ice chest. Be cautious. In all, a rusty refrigerator isn’t so harmful.

However, to be safe, I suggest you get rid of the rusty before it exposes you to various infections.

What Causes Rust On Outside Of Refrigerator?

Rust is a result of corrosion after the exposure of iron or its materials to moisture. Similarly, rust in your freezer occurs when iron, iron materials, or metals react with water moisture.  

Rust on the surface of your freezer, probably on the doors or somewhere, is a clear sign of an oxidation reaction occurrence.

Moisture, in most cases, is what prompts this kind of reaction. 

You may be wondering where the moisture or even water is coming from. They can come from the clean-up of the freezer.

When cleaning up your ice chest, its surface is prone to water and moisture(a mixture of water and air).

In addition, apart from moisture, some other factors or substances can likewise cause rust or speed up its formation.

 Let’s say acids and hydrated salts. These substances can increase the chances of rust on the surface of your freezer.

Hydrated salts are substances that contain ions and conduct electricity. They possess this corrosion ability and thereby aid rusting to a large extent.

To be practical, mix table salt, white vinegar, and hydrogen peroxide in a metal bottle.

Shake the bottle to and fro to properly mix the contents. Do the shaking for some time and stop.

You’ll discover that the hydroxide peroxide will start bubbling or producing bubbles because of its contact with the metal bottle. Consequently, rust will also start building up and forming. 

Having some drops of acid, hydrated salts, or even typical water can enhance the action of rust on your freezer’s surface. 

To be more guaranteed, get a refrigerator produced using stainless steel. Though it will still get rust, it will delay the rusting, unlike other metal/iron types.

This is because stainless steel appliances take time to rust.

In cases where the rust is not so deep, merely get rid of the rust stains or marks by cleaning them.

How To Keep Outside Refrigerator From Rusting?

To prevent rust on the outer part of your freezer, frequently eliminate any spill-over or drop from liquid substances.

Also, utilize a soft fabric to mop the freezer to a point where it’s dry.

Finally, I highly suggest the use of cleaners that your producers recommend. Typically, gentle soap and clean water will be suitable and okay for cleaning.

Commercial cleaners are not too safe and may enhance rust. They consist of substances like ammonia and bleach. If you still wish to use them, you can do so though once in a while.

Just so that you know, dust too can cause corrosion at times. Hence, you ought to occasionally wipe the outer part of your freezer with a dry fabric to eliminate dust or residue.

If you find tiny rust stains, then use a wet fabric instead. Most times, instead of utilizing a damp cloth alone, you can add a mild soap. The two will work perfectly.

 It’ll be nice if you can get warm water. Warm soapy water will work well too. You can likewise prevent rust on the outer part of your ice chest by applying a layer of wax.

This shielding wax coating will guard the fridge’s surface and protect it from rust.

The appearance of the freezer alone when you apply this coating is shiny and original. Alternatively, you can likewise use touch-up paint instead of wax coating.

Touch-up paints are special paints. You can get one on Amazon. Preventing rust on the outer part of your ice chest doesn’t require a lot.

However, for more efficacy, set your temperature regulator to a temperature of 78⁰F during cold weather and 68⁰F during hot weather. 

On a similar note, the cooling systems in your house dehumidify the entire home.

This dehumidification shields various appliances like refrigerators from rust, so keep the cooling systems frequently running.

How To Remove Rust From Inside Refrigerator?

Getting rid of the rust in your ice chest is easy. First, remove the items in your freezer and scrub the rust.

If the rust doesn’t go away, use a paste mixture of lime and salt, wait for some time, then clean everything off again.

To remove the rust in your freezer, disconnect the fridge from the main if connected. Then, relocate all the items and foodstuff to the freezer.

Don’t forget to place all the perishable items in a preservation machine or box.

When you’ve carried everything out of the refrigerator, scrub the rust away. You can use grit sandpaper to remove the rust.

If, after the scrubbing, you find that there are still more rust stains, apply a paste to the rust. This rust should be a mixture of salt or baking soda water and lime water in a ratio of 2:1

Lime is a good rust stain remover. To apply the paste on rust efficiently, utilize a scrubbing pad. Then, wait for about two hours or more to ensure the effectiveness of the paste.

After the waiting period, eliminate the remaining rust using the scrubbing pad. Next, you should use a wet fabric to remove the rust and paste. 

When you’re through all these processes, put your items or foodstuffs back into the refrigerator.

How To Prevent Rust On Refrigerators?

As a preventive measure against rust, coat the fridge’s surface with a unique type of paint called touch-up paint.

Coat it with this touch-up paint regardless of whether it’s a stainless steel appliance or it’s not.

There are many other alternatives or preventive measures aside from coating with touch-up paint.

For example, you can connect an air conditioning vent to a moisture-saturated room that contains essential appliances like fridges.

This air conditioning duct or passage connection assists in the removal of moisture-saturated air, thereby preventing rust scenarios.

Additionally, you can re-apply paint on the surface of your refrigerator, which you have painted before.

Repaint the fridge anytime you discover that rust has started developing. 

Don’t allow the rust to develop into something bigger and thicker. But before you paint the surface, remember to scour off the existing rust.


Rust, alternatively referred to as ferric oxide, isn’t dangerous. Even the inhalation of this ferric oxide can expose you to various health hazards only when you consume it over a long period.

Though rust in your refrigerator cannot harm you, you should be very careful. Its particles can get in your food. Try all you can to get rid of any rust in or on your refrigerator.
