Had a vendor bring me a couple of cornstick CI pieces today, both were nicely made but she had soaked them for several several several days in a vinegar bath. Both pieces have the surface texture of a cinder block even after cleaning with the E tank and scrubbed them by hand. The seasoning looks dull, dry and grey black after 2 rounds of oiling/heating. Is it possible for vinegar to make CI unseasonable ? My phone is dead so i will post a few pics tomorrow.:-?
