I am new to cast iron, my mom picked this up at a garage sale for me and i have a few questions about it. I dont have an e-tank or lye bath so i use 50/50 vinegar and water and it seems to take seasoning off when scrubbing with a SS brush. I am in the process of cleaning up this grill pan, my questions is, does anyone know who made this? i cant find any markings, probably an import for a big box store brand? also whats the purpose of the enamel handle and coating the outer rim, rust protection? can i remove the enamel and just season the entire thing?
