How should iron be stored to prevent rust and damage

Did you know that improperly storing a steam iron with water inside is one of the leading causes of premature appliance failure and rust formation? Following the correct storage protocol for both household irons and cast iron cookware is a simple yet crucial practice that extends their lifespan and preserves their condition.

Quick Summary

Correct storage for clothes irons and cookware involves thoroughly drying the item, allowing it to cool completely, and placing it in a low-humidity location. Correct positioning and protective layers prevent damage.

Key Points

• Empty Water Tanks: Always empty all water from a steam iron's tank after each use to prevent corrosion and mineral buildup.

• Ensure Complete Cooling: Always allow any iron to cool completely before storing to avoid safety hazards and condensation.

• Choose a Dry Environment: Humidity is the enemy of iron. Store all iron products in a cool, dry, and dust-free location to prevent rust.

• Apply Protective Layers: For cast iron cookware, a thin layer of oil after drying creates a protective seasoning. Use paper towels between stacked pans to absorb moisture.

• Store Upright: Clothes irons should be stored vertically on their heel rests to protect the soleplate and prevent leaks.

• Manage Power Cords: Avoid wrapping cords too tightly. For retractable cords, ensure a smooth retraction to protect the internal wiring.

Pre-Storage Essentials for All Iron Types

Before storing any item made of iron, a few universal rules apply to ensure longevity. Proper preparation is the most critical step in preventing rust, corrosion, and other damage, especially since oxygen and moisture are the primary drivers of this degradation. By mitigating these factors, you significantly prolong the life of your iron products, whether they are small appliances or heavy-duty cookware.

• Ensure it is completely cool: Never store an iron, hot or warm, as this can be a safety hazard and can trap moisture as it cools. Always wait until the item reaches a safe, ambient temperature.
• Choose a dry, cool environment: Humidity is the number one enemy of iron. High moisture levels in the air can lead to condensation and rust. Select a storage location that is not prone to dampness, such as a closet away from bathrooms or basements. For cast iron, this is particularly important.
• Keep it clean and free of dust: Dust can contain salts and other corrosive materials that accelerate rust formation. Ensure the surface is wiped clean with a dry cloth before putting it away. For cookware, this means cleaning and drying thoroughly after every use.

Storing a Clothes Iron

Proper storage of a clothes iron is essential for protecting its delicate soleplate and preventing mineral buildup in its water tank. Skipping these steps can lead to stains on your clothing and a shortened appliance lifespan.

Preparing a Steam Iron

1. Empty the water tank: This is the most crucial step for steam irons. Stagnant water, especially if it is not distilled, can leave mineral deposits that clog the steam vents and cause internal corrosion. After each use, empty all remaining water and leave the steam dial on the 'dry' setting to allow any residue to evaporate.
2. Clean the soleplate: Ensure the soleplate is clean and smooth. Residue from starches or fabric can build up over time. Clean it gently when cool with a damp cloth or a mixture of baking soda and water to remove stubborn marks.
3. Wrap the cord loosely: For corded models, avoid tightly wrapping the power cord around the iron. This can stress the wiring and cause internal damage. Instead, wrap it loosely or, for retractable models, ensure the cord retracts smoothly.

Where to Store It

• Store vertically: Always stand the iron upright on its heel rest. This protects the soleplate from scratches and prevents any residual water from leaking. It also promotes air circulation around the hotplate.
• Use a storage box or case: A dedicated storage box or bag can shield the iron from dust and accidental impacts.
• Choose a safe, stable shelf: Place the iron on a high, stable shelf in a cool, dry area, out of reach of children or pets.

Storing Cast Iron Cookware

Cast iron cookware is renowned for its durability, but it requires specific storage to prevent rust and maintain its seasoning.

Preparing Your Cookware

1. Clean and dry thoroughly: After each use, clean the skillet or pot with hot water and a stiff brush (avoiding soap if possible, to preserve the seasoning). Immediately dry the surface completely with a cloth or by placing it over low heat on the stove.
2. Apply a protective oil layer: While still warm, apply a very thin layer of cooking oil (vegetable or canola oil works well) to all surfaces using a paper towel. This creates a protective barrier against moisture.
3. Use a moisture absorber for long-term storage: For cookware that will be stored for an extended period, place a paper towel, a cup of rice, or a few lumps of cooled charcoal inside the pan to absorb any excess moisture.

Where to Store It

• Elevate it off the ground: Never store cast iron directly on the floor where moisture can accumulate. Use a wooden base, rack, or shelf to keep it elevated.
• Create air flow when stacking: If stacking multiple pans, place a paper towel or a soft cloth between each piece to prevent scratches and allow air to circulate, preventing moisture from becoming trapped.

Surface Protection	Store upright on its heel rest to protect the soleplate from scratches.	Apply a thin layer of seasoning oil. Use paper towels when stacking to prevent abrasion.
Positioning	Always store in a vertical position to prevent leaks and soleplate damage.	Can be stacked with protective layers or hung. Needs to be elevated off damp surfaces.
Humidity Control	Store in a cool, dry, dust-free cabinet.	Crucial to store in a very low-humidity environment to prevent rust.

Storing Specialty Irons

For items like soldering irons, the principles of keeping them clean and dry still apply, but with some key differences. After use, allow the soldering iron to cool completely in its holder. For long-term storage, it's recommended to clean the tip, re-tin it, and then store it in a clean, dry case along with accessories. This prevents the tip from oxidizing and maintains its performance. The Canadian Conservation Institute offers further guidance on proper metal object storage for sensitive items.

Conclusion: The Golden Rules of Iron Storage

No matter the type of iron product, the fundamentals of proper storage are clear: prioritize dryness, temperature, and physical protection. For clothes irons, emptying the water tank and storing the appliance upright on its heel rest are non-negotiable steps. For cast iron pans, a post-cleaning oiling and the use of moisture-absorbing materials are key to preventing rust and preserving the seasoning. By consistently applying these simple practices, you can ensure your iron tools and cookware remain in excellent condition for years to come, avoiding the common pitfalls of corrosion, damage, and poor performance.

Following these guidelines will not only protect your investment but also ensure that your iron is always ready for its next use.
