Simon, Love our cast iron pan. We have a Lodge outlet store nearby so I can only tell you my experience.
The store clerk was very knowledgeable. Told us to how to clean the pan and re-season the pan, etc.
!.) Told us to re-season the pan by cooking a pack of bacon.
2.) Clean the pan using a stiff kitchen dish / pan brush. Using only hot water. Wipe dry with a towel.
3.) Use a metal spatula to flip your food. Keep it flat against the bottom of the pan, so you do not create groves in the bottom of the seasoning layer.
4.) After cleaning...Use olive oil to lightly oil the pan after use.
5.) Told us to never cook with only tomatoes or tomato sauce for extended periods (simmer for hours). It can remove the pans seasoning coating and the sauce can taste metallic.
6.) If using on an electric stove top (glass top). Never go above med-high. Never slide the pan on a glass top range.
So, after following these tips. We have had great success with our pan over the past 5 years.
Look forward to hearing some more tips. You tube has some great videos too.
Mr. Toesup
