Food stuck and messy pan?
Pour hot water half way. Don't ever put cold water on a hot pan. Don't boil water in pan unless you have sugar heavily caramelized.
Cheap cast iron scrapers. Got it on amazon.
Scrap away the larger pieces. Should take only few second. Don't spend time here
Drain water but food is still dirty.
Sprinkle quick oats and a splash of water.
Use the pads of your fingers to vigorously. It should form a thin paste, the oats absorb excess grease and gunk without stripping the iron. Less than a minute for most cases. Fingers get soft too.
Rub butter stick or apply few drops coconut oil. Save trees and fat. These are rich fats don't pour away only to wipe everything with lots of paper( I used a very small piece)
Pan is seasoned and happy. Didn't waste a kwh energy to season it.
The essence of seasoning is to have the iron pores clogged with saturated(doesn't oxidize) fat all times. Avoid cooking liquid foods, at least melt butter while pan is hot until u wash it.
Don't use sponge unless it's coconut fibre. Best way to grow bacteria or get soap residue on pan.
