What's your go to method for a good thorough cleaning. I'm in the process of moving and paper wrapped all my cast iron but it still gets pretty dusty and I would like to start with a clean and fresh set in the new place.
 
Follow “cast iron chris” on instagram.

I use (GASP) soap and water and a steel scrubbie to clean cast iron. Then I season with a light coat of oil. Mostly I just use a couple of them frequently without cleaning at all until I dont want a flavor exchange ie until I dont want my grilled cheese sammich to taste like onions, etc. This keeps them non-stick ime.
 
Dawn dish soap and a scrub daddy (or whatever sponge you use). Heat up once rinsed and then thin coat of oil and back on the shelf for next time.
 
I never use any type soap.
Mine are seasoned slick.
Chainmail scrubber under the water coming out of the sink, heat pan to evaporate water, then coat with rendered tallow.
 
To clean some dust off I'd just use water and sponge with maybe a little Dawn. Now you mention a "clean and fresh set"; that sounds like stripping off your seasoning and starting new. That would take soak in some lye or oven cleaner. I prefer the lye but there are other tutorials out there. The lye can be found as Roebic Crystal Drain Opener. If I remember right, the ratio is 1 pound in 5 gallons of water and you basically let it soak for about 2 weeks. I use an 18 gallon tote about half full; pans fit well in the tote. The lye dissolves anything organic and the pans come out a light grey color. They need seasoned immediately after you rinse the lye solution and any organic remnants off. If your pans have any rust on them that will need additional attention.

Most of my cast iron knowledge is from: https://castironcollector.com/
 
If just cleaning dust off is your goal, any basic cleaning method will work. Soap doesn't harm the polymerized oils that are seasoning and, if soap harms your seasoning, your pan wasn't seasoned it was just greasy.

If you want to strip or remove that seasoning, lye or yellow cap oven cleaner methods are good for a couple pieces. For a larger collection, it might be worth making an e tank.
 
If stripping down to bare metal, old school oven cleaner is lye. Just put a pan in a garbage bag, spray the heck out of it, let soak a day or two, rinse with hose and repeat if needed.

If they are stripped to bare metal, going over them with a random orbit sander to take off the high points is well worth the effort before seasoning.

Restaurants quickly season pans by baking them at 450 to 500 degrees for 30-60 minutes. Many of the lower temp traditional ways seemed to make sense for a lot of years, but I see people all the time with mushy seasoning and it’s all I can do to not suggest they ignore what grandma taught them years ago and just give em a good bake.
