Whether you're in a hurry to get to the next dish or just want to clear up your stovetop, it's tempting to run a hot pan under water to start the cleaning process. However, doing so can cause thermal shock, which can ruin your pan. Thermal shock occurs when a material contracts and expands unevenly in response to temperature changes. This can cause warping, cracking, or chipping, and even if your pan doesn't warp, the finish can come off, causing chipped enamel or a degraded non-stick coating. So, what's the best way to wash a hot pan?

Thermal shock can damage your pan
To avoid thermal shock, it is crucial to let your pans cool down gradually before cleaning them. Allow the pan to reach room temperature naturally, and then wash it with warm, soapy water using a soft sponge or cloth. For tougher stains or burned-on food, you can use a stainless steel cleaner or a mixture of water and baking soda heated on the stove. By taking the time to let your pans cool properly, you can prevent thermal shock and extend the lifespan of your cookware.
Non-stick cookware is particularly susceptible to warping due to thermal shock because of its lighter construction compared to stainless steel or cast iron pans. When cleaning non-stick pans, avoid using abrasive cleaners, pads, baking soda, bleach, or liquid household cleaners as these can damage the finish. Instead, opt for a liquid dishwashing detergent and a non-abrasive sponge or soft-bristle brush. Additionally, it is recommended to hand-wash non-stick cookware rather than placing it in the dishwasher, as the high water temperatures during the sanitizing phase may damage the non-stick coating over time.
Cast iron pans should also be allowed to cool completely before washing. Avoid using soap, as it can remove the oil and seasoning necessary for cast iron. Instead, clean the pan with a stiff brush and hot water, then towel dry immediately to prevent rusting. Apply a light coat of cooking spray or vegetable oil while the pan is still warm, and wipe away any excess with a paper towel. By following these specific care instructions for non-stick and cast iron pans, you can help prevent thermal shock and maintain the integrity of your cookware.
In summary, thermal shock is a common issue that can damage your pans. By understanding the causes and effects of thermal shock and taking the necessary precautions during cleaning and maintenance, you can ensure the longevity and optimal performance of your cookware.

How to properly wash different types of cookware
It is important to let a hot pan cool down before washing it with water to avoid thermal shock, which can ruin your cookware over time. Once the pan has cooled, you can begin washing it.
Non-stick cookware
If you are washing non-stick cookware by hand, use a liquid dishwashing detergent and a non-abrasive sponge or soft-bristled brush. To remove difficult residues, use a liquid cleanser, then wash in hot, sudsy water. If your non-stick cookware is dishwasher-safe, use a dishwasher without bleach or citrus additives. Do not use abrasive pads, baking soda, bleach, or liquid household cleaners as these will damage the finish.
Cast iron
Cast iron pans should be allowed to cool completely before washing. Do not use soap, as this removes the oil and seasoning. Instead, clean the pan with a stiff brush and hot water. Dry the pan with a towel immediately after washing to prevent rusting. Then, apply a light coat of cooking spray or vegetable oil and wipe away any excess with a paper towel.
Carbon steel
Wash carbon steel cookware in hot water with a sponge. Avoid using dish soap or putting it in the dishwasher to preserve the seasoning. To clean scorched areas, add salt to the burned area and scrub with a sponge or bristle brush.
Stainless steel
Stainless steel cookware can be cleaned in the dishwasher or hand-washed in warm, soapy water. For stubborn food, mix one tablespoon of cream of tartar with one cup of water, boil the mixture in the cookware, allow it to cool, and then scrub the stain. You can use abrasive cleanser powder or baking soda to scrub away grease stains.
Ceramic
If your ceramic cookware is stained, try using a product like Dawn Powerwash to lift the stains. You can also soak the cookware in soapy water for 30 minutes, then sprinkle baking soda on a damp sponge and scrub in small circular motions to dislodge remaining food or grease. Do not use steel wool on ceramic surfaces.
Always refer to the manufacturer's instructions when cleaning your cookware, as some soaps and cleansers may not be appropriate for certain materials.

Why you should let your pan cool before washing
It is important to let your pan cool before washing to avoid thermal shock, which can cause irreversible damage to your cookware. Thermal shock occurs when a material experiences a rapid change in temperature, causing it to contract and expand unevenly. This can lead to warping, cracking, or shattering of the pan, affecting its ability to distribute heat evenly during cooking.
The impact of thermal shock depends on the construction and material of the pan. Non-stick pans, for instance, are more susceptible to warping due to their lighter construction. Similarly, thin metal cookware is more prone to permanent warpage than sturdier or thicker pans. By allowing the pan to cool gradually, you can prevent thermal shock and maintain the integrity of your cookware.
Another reason to let your pan cool before washing is to ensure effective cleaning. When a pan is too hot, it can be challenging to handle safely, and the heat may cause soap or cleaning solutions to evaporate quickly, reducing their effectiveness. Waiting for the pan to cool down makes it easier to handle and provides better conditions for thorough cleaning.
Additionally, some types of pans, such as cast iron pans, should not be washed with soap. Instead, it is recommended to clean them with a stiff brush and hot water, then towel-dry them immediately to prevent rusting. Applying a light coat of cooking spray or vegetable oil while the pan is still warm helps maintain its seasoning.
Finally, letting your pan cool before washing contributes to kitchen safety. Placing a hot pan under cold water can create a cloud of steam, potentially causing burns or obscuring your vision. By allowing the pan to cool, you eliminate this risk and create a safer environment for cleaning.

Why you shouldn't use soap on cast iron pans
It is generally recommended to let a hot pan cool down to room temperature before washing it with warm, soapy water. This gradual cooling prevents thermal shock, which can ruin your cookware over time, whether it is stainless steel, non-stick, or cast iron.
When it comes to cast iron pans, there is some debate about whether or not to use soap. Some sources claim that soap should not be used on cast iron pans because it removes the oil and seasoning necessary for this type of cookware. Instead, it is recommended to clean cast iron pans with a stiff brush and hot water, then towel dry to prevent rusting. A light coat of cooking spray or vegetable oil can be applied, and any excess can be wiped away with a paper towel.
On the other hand, some people argue that using a small amount of mild dish soap on a well-seasoned cast iron pan is acceptable. Modern dish soap is gentler than it used to be, and a seasoned pan has already developed a good layer of polymerized oil, so a small amount of soap won't make a significant difference. After washing with soap and water, the pan should be dried, and a light coat of oil can be applied.
Ultimately, the decision to use soap or not comes down to personal preference and the specific circumstances of your cast iron pan. If your pan is new or not yet well-seasoned, it may be best to avoid soap and stick to hot water and natural oils and fats to season the pan. If your pan is already well-seasoned, a small amount of mild soap is unlikely to cause significant harm.
In summary, while washing a hot pan with cold water is not recommended due to the potential for thermal shock, the use of soap on cast iron pans is a matter of debate. Some sources advise against it to preserve the seasoning, while others claim that modern soap is gentle enough not to cause harm. The decision depends on the condition of your pan and your personal preferences.
