Rinsing a hot pan with oil in it can cause thermal shock, which warps the pan and affects its ability to conduct heat evenly. This is due to the rapid change in temperature that occurs when a hot pan is rinsed with cold water, causing the metal to shrink rapidly and resulting in an uneven shape. Warped pans can cause oil to pool on one side and make it difficult to cook food evenly. To avoid this, it is recommended to let the pan cool down gradually before rinsing or washing it with hot water and a soft sponge or brush. This simple step will help maintain the longevity and functionality of your pans.

What You'll Learn
Thermal shock and warping
Thermal shock, caused by a sudden and significant temperature change, can damage your cookware. When a hot pan is placed under cold water, the metal cools too quickly, causing the pan to pull against itself. The bigger the temperature difference, the greater the shock. Even a small amount of cold water in the sink can cause a pan to warp, shatter, crack, or chip. Warped pans are a significant issue because they don't cook evenly, allowing oil to pool on one side and preventing them from sitting flat on an induction or electric cooktop.
The risk of thermal shock can be reduced by allowing pans to cool gradually on the stovetop or a heat-proof surface before washing. This gradual cooling process is essential for preventing warping or damage to your cookware. For example, you can let your pans cool down on the stovetop or a trivet before placing them in the sink to soak in warm, soapy water.
Certain materials are more susceptible to thermal shock than others. Glass, ceramics, and porcelain are more likely to crack or shatter due to their natural brittleness, while cast iron is more robust but can still warp under extreme temperature differences. Stainless steel is less prone to deformation but can still be affected. Thicker, well-constructed pans are generally better equipped to withstand thermal shock.
To reshape a warped pan, you can try heating it in an oven at 200°F (93.3°C) for about ten minutes or until it's warm to the touch. Place the heated pan upside down on a towel-covered workbench, then cover it with another towel and gently tap it with a mallet to reshape it.
Additionally, investing in high-quality kitchenware made from materials with higher thermal conductivity, such as copper, can help reduce the likelihood of thermal shock. These materials can better withstand sudden temperature changes, reducing the risk of warping or cracking.

How to clean a hot pan with grease
It is not advisable to rinse a hot pan with grease in it. Instead, it is recommended to let the pan cool down gradually on the stovetop. If you need to make space, place the pan on a trivet or another heat-proof surface. Once the pan has cooled, you can begin cleaning it.
Using Baking Soda
Sprinkle a generous portion of baking soda (about 1/2 cup to 1 cup) onto the grease. Let it sit for a few minutes, mix it a bit, and then you can scoop out the gravy-like grease mixture. After removing the grease, you can wash the pan as you normally would.
Using Dish Soap and Dryer Sheet
Add a few drops of dish soap along with some hot water to the pan. Submerge a dryer sheet in the water and let it sit for an hour. After an hour, remove and discard the dryer sheet and rinse out the pan using a scouring pad and dish soap.
Using Peroxide and Baking Soda
Place the pan inside a larger pan to heat up and leave it simmering for 10-20 minutes.
Using Vinegar and Baking Soda
Add a few drops of dish soap, along with some hot water, vinegar, and baking soda to the pan. Let the mixture sit for a few minutes, and then scour the pan.
It is important to note that you should not use soap when cleaning cast iron pans, as it removes the oil and seasoning. Instead, clean cast iron pans with a stiff brush and hot water, and then towel dry immediately.
Additionally, avoid using abrasive cleaners, cleaning pads, baking soda, bleach, or liquid household cleaners on non-stick pans, as they can damage the finish. Instead, hand-wash non-stick pans with warm, soapy water and a soft cloth.

Pans with non-stick coatings
It is not advisable to rinse a hot pan with oil in it. Thermal shock can occur when a hot pan is placed in cold water, causing the pan to warp, shatter, crack, or chip. The pan's finish can also be damaged, causing the chipped enamel or nonstick coating to end up in your food.
- Avoid using metal utensils on non-stick pans as they can scratch and damage the coating. Opt for wooden or silicone utensils instead.
- Do not use abrasive cleaners, steel wool, or harsh cleaning pads on non-stick pans. These can scratch and damage the coating.
- Hand-wash non-stick pans with mild dish soap and a soft sponge or cloth. Ensure the pan has cooled down before washing.
- If food is stuck on the pan, fill it with warm water and let it soak for a while before washing. You can also use a gentle scrubber to remove stuck-on food.
- For stubborn, burned-on food, create a paste with baking soda and water, apply it to the pan, and let it sit for a few minutes before wiping it clean.
- Some non-stick pans can be placed in the dishwasher, but always check the manufacturer's instructions first. Choose a gentle cycle and avoid using harsh detergents or bleach.
- To restore the non-stick properties of your pan, you can re-season it with a thin layer of vegetable oil or cooking spray. Heat the pan over medium heat for a few minutes, let it cool, and then wipe away any excess oil with a paper towel.
Non-stick pans typically have a lifespan of three to five years, after which the non-stick coating may start to degrade and lose its effectiveness. Some popular types of non-stick pans include:
- PTFE-coated pans: PTFE, or polytetrafluoroethylene, is a synthetic polymer that repels water and reduces friction, making it an effective non-stick coating.
- Ceramic-coated pans: Ceramic coatings, such as sol-gel, are marketed as a "'greener' alternative to PTFE." However, they tend to lose their non-stick properties faster and may need to be replaced more frequently.
- Carbon steel and cast-iron pans: These pans are naturally non-stick and can be pre-seasoned with vegetable oil. They are durable and compatible with induction cooktops.

Why you shouldn't use soap on cast iron pans
It is not advisable to rinse a hot pan with oil in it. Instead, you should let the pan cool down gradually on the stovetop. If you need to make space, place the pan on a trivet or another heat-proof surface. Repeated quenching of hot pans under cold water can damage the pan and cause permanent warpage, especially if the cookware is less sturdy or made with thin metal.
Now, coming to your second query, here are the reasons why you should avoid using soap on cast iron pans:
It removes the seasoning: Cast iron pans are seasoned with oil to create a natural non-stick coating. Traditional soaps can strip away this seasoning, leaving your pan more susceptible to rust and less non-stick.
It's unnecessary: A well-seasoned cast iron pan is naturally non-stick, so food residue should come off easily with just hot water and a stiff brush or scrubber. You can also use natural abrasives like salt or baking soda to help scrub away tougher bits without damaging the seasoning.
Modern alternatives exist: If you feel your pan needs a deeper clean, there are modern dish soaps that are much gentler than traditional soaps. These soaps are designed to be used sparingly and won't harm your pan's seasoning. However, it's still recommended to avoid using soap regularly, as it can build up over time and affect the pan's performance.
Heat sterilization: After rinsing your cast iron pan with hot water, you can heat it on the stove to ensure it's completely sterilized. This step also helps to evaporate any remaining water and prevent rusting.
Oil conditioning: After rinsing and drying your cast iron pan, you can apply a light coat of cooking spray or vegetable oil. This step helps maintain the pan's seasoning and prevents rust.
In summary, while modern dish soaps may be safe to use sparingly on cast iron pans, it's generally unnecessary and may negatively impact your pan over time. The traditional method of using hot water and natural abrasives is effective and helps maintain the pan's seasoning.

How to avoid damaging your pans
When it comes to pans, especially non-stick pans, there are several things to keep in mind to avoid damaging them. Here are some tips to help you keep your pans in good condition:
Avoid sudden temperature changes: Do not put a hot pan directly into cold water. This can cause thermal shock, which can lead to warping, shattering, cracking, or chipping of the pan. Instead, let the pan cool down gradually on the stovetop or a heat-proof surface before washing it.
Use proper cleaning methods: Avoid using abrasive cleaners, steel wool, or scouring pads on non-stick pans as they can damage the finish. Instead, opt for soft sponges, soft brushes, or microfiber towels with mild dish soap. For burnt-on food, you can use a stainless steel cleaner or a mixture of baking soda and water heated in the pan.
Avoid non-stick cooking sprays: Cooking sprays can burn at lower temperatures than the non-stick coating, creating a residue that builds up over time and damages the surface. Instead, use cooking fats like butter or oils such as canola, olive, vegetable, or corn oil. Add the fat to the pan before heating it up to enhance the non-stick effect and prevent the release of unhealthy fumes.
Avoid high heat: Non-stick pans are not designed for high heat. High temperatures can damage the coating and cause the release of harmful toxins. Stick to low or medium heat when using non-stick pans.
Avoid metal utensils: Metal utensils can scratch and damage the non-stick surface. Use wooden spoons or silicone utensils instead to protect the coating.
Avoid storing food in the pan: Storing food in the pan can cause additional wear and tear on the non-stick finish. Transfer food to a separate container for storage.
By following these tips, you can help extend the lifespan of your pans and avoid common mistakes that can lead to damage.
