NYRA® Pure Original Loha Kadhai/Iron Kadhai Heavy Bottom/Lokhandi Kitchen with Golden Handle (Small - 700 ml)

I realised after purchase that there is a non stick coating on the kadai surface, missed reading the detailed description before I ordered. This should be mentioned on the top and also along with the photo, so that its not missed by customers.It heats up too quickly and if you're careful in managing the heat, it cooks well and takes less oil to cook. Frying works best in this kadai.But the inner as well as outer surface gets browned very easily and takes a good amount of heavy scrubbing to clean it.I made dal and left it in there for half hour, and the inner side above the border of the dal upto the top edge of the kadai looked like it has caught rust. I finished my meal, emptied the kadai, rinsed it in water, rubbed salt and lemon all over the kadai and left it for some time. Then scrubbed heavily with dish soap.Not sure if I'm missing something or using it wrong.
