Can rust in dishwasher hurt you? In these modern days, with advanced technology, dishwashers are standard machines seen in households since they are efficient and effective in cleaning dishes such as pots and holding other utensils.

How would you feel when the dishwashers get rust? Would rust be dangerous or harmful to you? 

Dishwasher rusting comes when the entire protective covers and coating start to wear, tear and fade. Reasonably, when the heating cycle becomes excessively hot, the heat damage the vinyl coating allowing air or oxygen to reach the internal iron part causing it to rust. Similarly, mishandling of dishwashers, for instance, by overloading them, gradually tear the coat away.

It is also essential to know that utensils improperly placed on the rack cut the covers and coating. Moreover, dishwashers’ usage over time lowers the quality of covers and coating, making them wear and fall off. Consequently, over a number of years, the rust can be collected and deposited into human internal body systems during meals or dropped and scrubs the users’ skins.

The abandoned dishwasher system gets spots of a reddish or brown layer that rust. Utensils such as kettles and cutlery could rust, and drops some rusting on washers when placed on top of them. Rust is formed when oxygen reacts with the interior beneath the dishwasher’s protective coating, constituting iron in the presence of water or a humid atmosphere of moisture. 

Using a rusty dishwasher can harm the user or people close to the machine. Typically, rust is a health hazard substance. If a rusted dishwasher cuts you, you risk getting tetanus. Tetanus can affect and damage your nervous system, leading to powerful muscle spasms or loss of control of your muscle movement. 

Although tetanus is caused by a bacteria strain known as Clostridium tetani found in animal wastes deposited into the soil, it can find its way into your dishwasher through rust as dust. So, when a rusted dishwasher’s metallic parts scratch or break your skin, it exposes you to the risk of getting tetanus. When such an accident occurs, seeking proper medical attention is required, particularly if your dishwasher is rusty. 

A rusty dishwasher is not suitable for cleaning food utensils. If rust, especially in a large amount, is accidentally ingested, it can bruise your throat, stomach valves, and other gastrointestinal organs, which can lead to discomfort from pain, headache, or hemochromatosis disease, which is the body retention of excess iron which can cause issues such as cancer, irregular heartbeats, or liver cirrhosis.

Other diseases associated with working with rusted machines, including dishwashers, include:
•    Irritation of the eyes from the dust
•    Siderosis-a disease that affects the brain and spinal cord because of iron overload

Is it Safe to Use a Dishwasher With Rust

Is it safe to use a dishwasher with rust? is one of the most often asked questions about dishwashers. There are many misconceptions about this issue, but it is not unsafe to use a dishwasher with rust. Rust in the dishwasher does not pose any health risk.

Rust can form on metal surfaces due to water and oxygen exposure. It can be caused by a number of factors, including harsh detergents and hard water. Rust is also more likely to form if the dishwasher or other metal surfaces have been scratched or exposed to abrasive substances such as bleach or lime scale.

The most important thing to know about rust in your dishwasher is that it has no effect on its ability to clean dishes. In fact, rust will not cause any damage during normal use and will have no effect on the performance of your dishwasher.

Rust on dishwasher racks is not dangerous or harmful at all. The only risk factor would come in when there is so much accumulated rust on your dishwasher racks that it’s now leaving behind rust residue on your utensils. This can be dangerous as the rust residue may be ingested when the utensil is in use.

When you notice these rust stains on your dishes, it might be a good time to replace your dish racks or get them cleaned thoroughly by sanding the affected area.

Rust spots in your cutlery/dishes can be caused by a number of factors and can be very difficult to diagnose. Salty and acidic water can further accelerate the rusting process. Separating your shiny cutlery from the rusted ones would go a long way in preventing this from spreading to your other cutlery, especially if the issue is from coming from a rusted dishwasher rack. Stainless steel cutlery is durable and rust-free – we recommend using these instead as they won’t get any rust spots.

How to Prevent Rust in Dishwasher

You might be surprised to see your dishwasher with rust spots, yet you thought it was coated with rust-resistant material. You are likely to see rust spots on the cutlery after washing it in the dishwasher. This may result from prolonged exposure to untreated water, excessive chemical levels in your water, or lack of proper rinse-off before washing.   

Here are some of the critical points to prevent rust in a dishwasher:

• Ensure all food items/waste are removed from the cutlery before washing with the dishwasher.
• Confirm you are using the right type and dosage of the cleaning detergent.
• Avoid using items or cutlery tools that have been exposed to acids such as fruit acids or salts, such as egg slicers, in your dishwasher. The rust on them will spread on your machine.
• Use specialized dishwater cleaning substances or attach rust filters or iron removal devices to remove all the stains responsible for rusting.
• Ensure metallic dishes and items such as knives and spoons are rinsed thoroughly since acidic food on them can erode the washer coating leading to rusting that can affect the whole dish washer’s machine system.

Additionally, when blisters appear on the washer’s rack is a sign of the beginning of the rusting process. This process is prevented by precisely placing the dishes. For example, you should put utensils such as pots upside to allow complete drying of water.
