I got my PC oven cleaned up and wired this weekend. I now have 220v in the garage, and the proper plug on the oven. I used two cans of heavy duty oven cleaner, and got everything ‘mostly’ clean. However, there is still some food residue left behind. Will this cause a problem with my powdercoating efforts? Should I make sure it’s all spotless, or can I fly with what I have?
