Never give up on cast iron. We made a trip to our homeplace over the weekend. My mother-in-law knows how much I love cast iron. She had purchased these kettles in a set many years ago. Maybe as many as 50 years ago. I think she told me it was a 20 piece set and it cost about $20.00. ( thats says it was a long time ago) She had stored them in a building many years ago. We went on safari to search for them. When we found them I thought “Maybe they are too far gone”. But I brought them home and searched the internet for ways to clean them up. First I used an equal part of salt and oil. Rubbed that in(really good) with a cloth. Then for the really stubborn spots of rust, I used a brillo pad. Washed them in soapy water and reseasoned them. ( To season cast iron, coat the kettle with a light coat of oil. Turn upside down on a cookie sheet and bake at 250-300 degree oven for about l hour) I was so pleased with the result. I couldn’t wait to post about it. The largest kettle she called a pinto bean pot. I can just taste how good beans will be cooked on our wood stove this winter. Thanks so much, Judy. So don’t throw that old cast iron out. Re-do it. It’s worth the effort. God Bless.
