Tawas and kadhais are among the most frequently used utensils in Indian kitchens. From cooking vegetables and rotis to preparing tempering, these vessels are exposed daily to high heat, oil and spices. Over time, a thick black layer of soot forms on their undersides. Initially light, this deposit gradually hardens and becomes difficult to remove.

Apart from spoiling the appearance of the utensil, the black crust also affects heat absorption, reducing cooking efficiency. Many people resort to expensive chemical cleaners or excessive scrubbing, which can damage the surface and cause unnecessary strain. However, several simple home remedies can remove this stubborn layer quickly and effectively.

Baking Soda and Vinegar Method

This is one of the most effective ways to remove black deposits. Turn the pan or wok upside down and sprinkle a generous amount of baking soda over the blackened area. Pour a small amount of white vinegar on top. As the mixture begins to foam, it loosens the accumulated grime. Leave it for 10–15 minutes, then gently scrub with a scrubber or coarse cloth. The soot should come off with minimal effort.

Lemon and Salt Solution

For those who prefer a natural cleaning method, lemon and salt work well together. Cut a lemon in half, sprinkle coarse salt on the cut surface and rub it over the blackened area. The acidic properties of lemon combined with salt help break down the grime. Rinse thoroughly with water after scrubbing.

Hot Water and Washing Powder Soak

Fill a bucket or tub with hot water, enough to immerse the underside of the utensil. Add a small amount of washing powder and soak the pan or wok for about 30 minutes. The heat softens the soot, making it easier to remove. After soaking, scrub gently and rinse clean.

Using Tamarind Paste

Tamarind can also be used as an effective cleaning agent. Soak tamarind in hot water and make a thick paste. Apply it to the blackened surface and leave it for around 20 minutes. The natural acidity helps loosen old, stubborn deposits. Scrub and rinse with water for best results.

Baking Soda and Dishwashing Liquid Paste

For heavily stained utensils, mix baking soda with dishwashing liquid to form a thick paste. Apply it evenly to the underside of the pan or wok and let it sit for 15–20 minutes. Scrub with a scrubber and rinse. The dishwashing liquid cuts through grease, while baking soda helps lift the soot.

An Easy Kitchen Fix

With these simple, cost-effective methods, even old and stubborn black stains can be removed without damaging utensils. Regular cleaning using mild methods can prevent heavy buildup and help maintain both the appearance and efficiency of your cookware.
