I did not have much luck with the pre-seasoning on a Lodge 9 quart dutch oven. The seasoning was kind of gummy and did not really hide the rough finish of the pot's interior. It was a laborious but worthwhile endeavor to remove the factory seasoning and 'sand' down the rough interior with Brillo soap pads, silicon carbide abrasive paste, then wire cup & wheel brushes and finally with brown soap, hot water and a stiff pot brush. It's now a pleasure to use without having to worry about grating down my wood spoons when stirring and scraping down the pot's contents. The smoothed finish is also easier to clean.
I used several thin applications of corn oil to re season the pot. For maintenance, I clean the pot with warm to hot water and a stiff brush or a blue scotch brite pad, rinse with very hot water, dry with paper towels, heat on stove top to complete drying, and then apply a thin coating of peanut oil to the hot pot.
