Stripping Stainless Steel: Removing Teflon Coating

Teflon coating on stainless steel pans can be removed using a variety of methods, including abrasive blasting, burning, chemical solvents, and sanding. However, it's important to note that some methods may not be suitable for home use due to safety concerns. Burning Teflon, for example, produces toxic fumes and should only be done in industrial settings with proper ventilation. Similarly, chemical solvents like n-methyl-pyrrolidon are highly specialised and not recommended for home use. Sanding or abrasive blasting with aluminium oxide blast media are often suggested as the most suitable methods for removing Teflon from stainless steel pans at home, although they can be time-consuming and labour-intensive. It's also worth noting that removing the Teflon coating may affect the performance of the pan, and proper safety precautions should always be followed to avoid inhaling any harmful chemicals.

Use baking soda

To remove Teflon coating from a stainless steel pan using baking soda, follow these steps:

Method 1: Baking Soda and Water Paste

• Wet the pan with water.
• Add baking soda to form a paste or slurry.
• Let the mixture sit for a few minutes.
• Use a scouring pad or the scrubby side of a sponge to scrub off the Teflon coating.
• Repeat the process or let it sit overnight if the Teflon coating does not come off on the first try.

Method 2: Boil Water and Baking Soda in the Pan

• Add 1/4 to 1/2 cup of baking soda to the pan.
• Pour in 1/4 cup of water.
• Bring the mixture to a boil.
• As the water evaporates, scrub off the film of baking soda and Teflon coating with a scrubby sponge or kitchen scrub brush.

Method 3: Submerge Pan in Boiling Baking Soda Solution

• Fill a large pot with water and place the pan inside, submerging it completely.
• Bring the water to a boil.
• Add 1/4 to 1/2 cup of baking soda to the pot.
• Reduce the heat to a gentle boil and let it boil for 15 to 30 minutes.
• Remove the pan from the boiling solution while it is still hot.
• For stubborn stains, add more baking soda and water to the pan to create a paste or slurry. Scrub away the remaining Teflon coating.

Warnings:

• Avoid using steel wool, scouring pads, oven cleaners, bleach, or strong abrasive cleaners as these can scratch your cookware.
• Always allow pots and pans to cool before washing; hot stainless steel cookware can warp if submerged or splashed with cold water.
• Thoroughly dry your pans immediately after cleaning to prevent the development of water spots and dried, white calcium spots.

Sandblasting

Overall, while sandblasting is a viable option for removing Teflon coatings from stainless steel pans, it is a specialised process that requires professional equipment and expertise.

Use an angle grinder

To remove the Teflon coating from your stainless steel pan using an angle grinder, you will need the following items:

• An angle grinder
• A wire cup brush attachment
• Metal polish
• Dish soap
• A sponge or soft scrubber
• Gloves
• Masks
• Goggles

Firstly, put on your gloves, masks, and goggles for protection. Then, attach the wire cup brush to the angle grinder and switch it on. Start wiping off the Teflon coating from your pan. Once the coating is completely removed, apply metal polish to the pan. To do this, attach the polishing disk to the angle grinder and begin polishing.

After polishing, take some dish soap and squeeze it into the pan. Wipe the pan with a sponge to remove the polishing gel. Then, rinse the pan in clean water and leave it to dry.

This method of removing the Teflon coating from your stainless steel pan is very effective and less time-consuming compared to other methods such as using sandpaper. However, it is important to note that removing the Teflon coating may change the way your pan cooks, and you may need to use it differently than before. Additionally, always ensure that you are working in a well-ventilated area and wearing proper protective gear to avoid inhaling any harmful chemicals.

Use a wire brush

Using a wire brush is an effective method to remove the Teflon coating from your stainless steel pan. Here is a detailed, step-by-step guide on how to do it:

Step 1: Prepare the Work Area and Gather Materials

• Find a well-ventilated area, preferably outdoors or in a room with good airflow.
• Put on protective gear, including gloves, safety goggles, and a face mask, to shield yourself from any released chemicals.
• Get a wire brush attachment for your drill or angle grinder. You can also use a rotary wire brush if you have one.

Step 2: Remove the Teflon Coating

• Put on your protective gear if you haven't already.
• Attach the wire brush to your drill or angle grinder.
• Switch on the tool and carefully begin brushing away the Teflon coating. Work systematically, covering the entire coated surface.
• Continue until the coating is completely removed, and you see the bare metal of the pan.

Step 3: Polish the Pan

• With the coating removed, it's time to polish the pan. This step will help smooth out any scratches or imperfections left by the wire brushing.
• Attach a polishing disk to your drill or angle grinder.
• Apply a suitable metal polish to the pan.
• Start the tool and begin polishing the pan's surface. Work in sections, ensuring you cover the entire area.

Step 4: Clean and Season the Pan

• Once polishing is complete, it's time to clean and season the pan for future use.
• Wash the pan with a mild dish soap and warm water to remove any polishing residue. Rinse thoroughly and dry the pan.
• To season the pan, preheat it for about two minutes.
• Pour a small amount of oil (grapeseed, coconut, or flaxseed oil work well) into the pan and spread it evenly across the surface.
• Heat the pan until the oil begins to smoke, then remove it from the heat and allow it to cool.
• Use a cloth or paper towel to wipe out any excess oil.
• Repeat the seasoning process 2-3 times for the best results.

Remember to work carefully and deliberately throughout the process, especially when using power tools. Always wear protective gear and ensure proper ventilation to avoid inhaling any released chemicals. Good luck, and happy cooking!

Use a drill with sandpaper

To remove the Teflon coating from your stainless steel pan using a drill with sandpaper, you'll need to take the following steps:

First, ensure that your pan is made of stainless steel. Removing Teflon coating from aluminium pans is not recommended as the aluminium will react with food and may cause serious health issues.

Next, put on safety gloves and attach a sanding disc to your drill. You can also use a wire cup brush attachment if you have one. Turn on the drill and begin to sand the pan's surface, applying some pressure. Continue this process until the black Teflon coating peels off, revealing the silver colour of the stainless steel underneath.

Once the Teflon coating is removed, change the drill attachment to a sanding disc with a finer grit. Sand the pan's surface in a clockwise and anti-clockwise direction to reduce the appearance of scratches. This step requires patience and energy as it may take some time.

Finally, wash the pan with dish soap and rinse it thoroughly. You may need to season the pan 2-3 times to make it smooth and ready for use again.
