Whether you can wash a hot pan is a highly debated topic. While some people advocate for washing pans with hot water while they are still hot, arguing that it makes cleaning easier and prevents warping, others caution against it, citing the dangers of thermal shock, which can damage or break cookware. Thermal shock occurs when a hot pan is subjected to a sudden change in temperature, causing the metal to contract rapidly and affecting the pan's structural integrity. Experts recommend allowing pans to cool gradually before washing them with warm, soapy water and a soft sponge or cloth to avoid damage and ensure effective cleaning.

Using hot water to wash a hot pan
It is generally advised to let a hot pan cool down before washing it with water, as introducing a sudden change in temperature can cause thermal shock, which may ruin the pan. Thermal shock can cause the pan to warp, crack, chip, or shatter. Warped pans are a major problem because they won't cook food evenly, allowing oil to pool on one side. Even if the pan doesn't warp, the finish can come off, and the chipped enamel or non-stick coating may end up in your food.
However, some sources suggest that washing a hot pan with hot water can be effective and safe. Modern pans are less likely to warp when hot water is used. The residue is also easier to clean off. One suggestion is to add hot water and detergent to the pan to soak while you eat, then clean it afterward. Another suggestion is to fill the pan with hot water and dish detergent, and even turn the heat back on for a few minutes to release the residue.
If you are going to let the pan cool down before washing it, it is best to let it cool gradually on the stovetop. Placing the pan on a trivet or another heat-proof surface can help make space. Once the pan is cool enough to touch, you can begin by wiping it with a clean sponge or cloth. If there is still food residue stuck to the pan, wash the pan with warm water and use a scrubber to remove the residue.
For cast iron pans, it is recommended to clean them with a stiff brush and hot water. Towel-dry the pan immediately after washing to prevent rusting. While the pan is still warm, apply a light coat of cooking spray or vegetable oil, then wipe away any excess with a paper towel.

Thermal shock and how it ruins your cookware
Thermal shock is a common issue in the kitchen, and it can ruin your cookware. It occurs when there is a rapid change in temperature, causing your cookware to warp or crack. For example, when a hot pan is placed under cold water or blasted with cold water from the faucet, it experiences thermal shock, which can lead to warping and cracking. This sudden change in temperature causes different parts of the pan to expand or contract at different rates, resulting in internal stress and structural damage.
The severity of the damage caused by thermal shock depends on the material and quality of the cookware. For instance, cast iron pans can crack or warp, especially when they are of lower quality or have flaws. Similarly, coated aluminium pans can quickly become weaker and warp due to thermal shock, as the high heat causes the coating to deteriorate. Stainless steel pans may also warp slightly but often return to their original shape with regular use.
To prevent thermal shock, it is essential to avoid extreme temperature changes. Allow your cookware to cool gradually before washing it with lukewarm or room-temperature water. This slow cooling process allows the pan to return to its original condition without warping or cracking. Additionally, when using the oven or stovetop, let your cookware heat up slowly rather than immediately cranking up the heat.
When purchasing cookware, look for thermal shock-resistant options to minimize the risk of damage. Fully vitrified plateware and bakeware, which have been heated to boiling before firing, are typically stronger and more resistant to thermal shock. Sheet pans made of thick, high-gauge aluminium with sturdy rolled edges are also recommended for better resistance to temperature changes.
By understanding the causes and consequences of thermal shock, you can take the necessary precautions to protect your cookware and ensure its longevity in the kitchen.

The dangers of washing a hot pan
Washing a hot pan can be dangerous for several reasons. Firstly, it can cause thermal shock, which occurs when there is a rapid change in temperature, such as when a hot pan is immersed in cold water. This can lead to warping, cracking, or breaking of the pan. The pan may not sit flat on the stove anymore, affecting its cooking performance. Even a small amount of cold water at the bottom of the sink can be enough to cause thermal shock. Thin non-stick pans are particularly susceptible to thermal shock, but it can also affect thicker cast iron pans.
Secondly, washing a hot pan can be a safety hazard. If you carry a large thermal mass, such as a cast iron pan, to the sink and touch it with bare wet hands, you risk burning yourself. Additionally, someone else in the kitchen may accidentally pick up the hot pan from the wash area, potentially causing injury.
Thirdly, washing a hot pan with cold water can make it more difficult to remove burned-on food residue. The food can get scorched onto the pan, requiring more elbow grease to scrub it off later. Instead, it is recommended to let the pan cool down gradually and then use hot water and detergent to soak and clean the pan.
Furthermore, for certain types of pans, such as cast iron, using soap and water can remove the oil and seasoning, leading to rusting. Instead, a stiff brush and hot water should be used, followed by a light coat of cooking spray or vegetable oil.
Lastly, for non-stick pans, using abrasive cleaners or cleaning pads, baking soda, bleach, or liquid household cleaners can damage the finish. It is recommended to hand-wash non-stick pans with a non-abrasive sponge or soft-bristle brush and liquid dishwashing detergent.

How to wash a nonstick pan
It is important to note that non-stick pans should not be washed in the dishwasher, even if the manufacturer labels them as dishwasher-safe. The high heat and harsh detergents can damage both the non-stick interior and the anodized exterior. Instead, hand-wash your non-stick pan after each use to keep it clean and free of rust and residue.
Step 1: Allow the Pan to Cool
Before washing your non-stick pan, it is important to let it cool down. Quickly transitioning from hot to cold can create thermal shock, damaging your cookware over time. Place the pan on a stove or a cooling rack to let it cool down gradually. Avoid placing hot pans under running water, as this can be dangerous and cause thermal shock, potentially warping your pan.
Step 2: Soak the Pan
Once the pan has cooled, fill it with warm water and add a small amount of dish soap. You can also add a teaspoon of salt to the water to help break down any grease or residue. Let the pan soak for about 10 to 20 minutes. Soaking will help loosen any stubborn residue or burnt-on food, making it easier to clean.
Step 3: Scrub Gently
After soaking, use a soft sponge or cloth to gently scrub the pan. Avoid using abrasive sponges, steel wool, or metallic scouring pads, as these can damage the non-stick coating. For stubborn residue, create a paste with baking soda and water. Apply this paste to the affected areas and let it sit for about 15 minutes before gently scrubbing and rinsing the pan.
Step 4: Rinse and Dry
Rinse the pan thoroughly with lukewarm water to remove any soap residue. Dry the pan immediately by hand using paper towels or a soft dishcloth. Ensure that the pan is completely dry before storing it away to prevent rusting.
Step 5: Season the Pan (Optional)
To maintain the non-stick properties and prevent rust, you can season the pan after it is clean and dry. Rub the surface with a small amount of vegetable oil using a paper towel, then wipe off the excess with a clean paper towel. This will help protect the pan and keep it in optimal condition.

Frequently asked questions
No. Washing a hot pan in cold water can cause thermal shock, which can warp, crack, chip or shatter your pan. It's best to let the pan cool down gradually before washing it with hot water.
Thermal shock is when metal expands when heated and contracts when cooled. So, when you take a hot pan and run it under cold water, the expansion and contraction are forced at an unnatural speed, which can damage your cookware.
You can add hot water and detergent to the pan and let it soak while you eat. After that, you can clean it with a sponge. If there is any residue left, you can use a liquid cleanser and then wash the pan in hot, soapy water.
For tougher stains, you can scrub your pan with a water and vinegar mixture. If that doesn't work, you can use a paste of coarse kosher salt and water as a gentle abrasive.
