Tbf the cast iron i’m cooking out of was found as scrap in the woods. I wash with soap regularly, and use normal oil/butter qty’s. I just don’t dishwasher it, not that i have a dish!asher XD. I’ve seasoned it one single time which is right after i found it. It’s been a year.
Ehhh… I’ve taken the 100LL avgas shower. At this point, a year of cooking later, the damage is done ig. Ill grab a test kit tho.
