How to recover cast iron skillet with melted fiber on it

Great question - very well put!

Your chef advice is sound. I have been cooking with cast iron skillets for longer than I care to admit (old guy) and at first they can be intimidating but in the end, they become your go to pan especially for searing/cooking hot.

You asked the same question several times, "is the residue safe?" It's as safe as the cooking oil you use to season it and as clean as you were able to get it before storage. A clean oiled cast iron pan in your cupboard is safe. Sometimes, I will wipe the old residue off with a paper towel just before cooking just to get any dusty nasties off of the cooking surface.

Basically, this is how I use my cast iron.

1) Remove from cupboard

2) Take a look - is there any dirt, debris, dust or corrosion. If so, remove. (Corrosion being the most difficult but a little scouring and re-seasoning will do the trick.)

3) Heat pan thoroughly before cooking - again, the heat will kill anything you can't see but don't want to consume.

4) Cook your food.

5) Eat your food (grin).

6) Clean the pan (NO SOAP)

• a) Remove any remaining food with a scouring brush - in the sink, use hot water and elbow grease.
• b) Fill pan with hot water
• c) Place on burner (on high)
• d) Wait till it comes to boil
• e) Turn off burner and remove from heat (careful - water is hot).
• f) Pour out water and brush clean with scouring pad/brush
• ---If clean, let cool to touch - if not, repeat b-f
• g) When cool, pour a small amount of cooking oil into pan
• h) with a paper towel, spread cooking oil all over the inside of the pan
• i) With the same paper towel, wipe the outside of pan and handles, bottom, everywhere
• --You're looking for a nice coating of oil - no pooling - just a nice gloss. This will prevent corrosion and keep the pan seasoned.

7) Once pan in completely cool, return to cupboard.

Tip - if you were unfortunate enough to leave the braising residue in your pan for a few days and it's a sticky mess, you can try filling it with warm water and putting a couple tablespoons of dish washing crystals (Cascade works best for me) in the pan. These "crystals" contain little enzymes that will "eat" the residue and make cleaning much easier. Don't leave in too long, about an hour or so - repeat if necessary. (Works on other pans too but not recommended for Teflon or non-stick pans.)

Tip 2 - I stack my pans in storage. To prevent metal to metal contact (not good), I put a paper towel between each pan. Be careful that the cast iron is not touching your other pans. Dissimilar metals have a way of talking to each other (causes corrosion on both).

There you have my tried and true method of caring for a cast iron pans. For some reason, I find myself craving some cornbread.

Good Luck!

"Are they OK to cook on?" can mean:

1. Will I die within 24 hours after using them?
   No!
2. Will I die within a few years?
   No!
3. Will I get ill within a few years if I use them daily and lick all the juice off them after each use?
   Meh, very probably not!
4. Does it look gross and might the food taste of rust?
   Yes!

So, thoroughly clean them before each use with a copper wire brush and after each use, clean them again and then oil them with some nice olive oil¹ and a paintbrush as soon as possible after using them and continue using them regularly. ;-)

Note¹: Don't soak them in olive oil: just some nice clean sweeps with the paintbrush lightly dipped in olive oil to make a thin film everywhere to prevent atmospheric oxygen from rusting it any further...
