Learning how to clean cast iron seemed like a daunting task for me before I knew all the hoodoo-voodoo tricks, but I have to be honest: it’s one of the easiest things in the world to clean. Especially if you do it my way, which only uses TWO ingredients, both of them natural!
Gotta love that.
We have two major pieces of cast iron in my house: a cast iron skillet we use every day, and a cast iron wood burning stove. The skillet is no big deal because we use it often enough it doesn’t rust, and when we do need to clean it we just heat it up, add olive oil and wipe it off with a cloth.
The cast iron stove on the other hand, is a bit of an endeavor. Poor, rusted out cast iron stove. Luckily it doesn’t need to be cleaned very often and I usually have the cleaning ingredients on hand. The roof above the chimney leaks so the stove ends up rusting pretty badly on top. It’s no bueno, but easy to fix!

2 Ingredient Cast Iron Cleaner How To
- fresh lemons
- coarse salt
- optional: olive oil to seal the surface once cleaned
That’s it! All you need for this how-to is a few fresh lemons (more or less depending on the size of the cast iron project you’re cleaning) and some coarse salt. Easy peasy, lemon squeezy.
(you have no idea how long I’ve waited to use that in the proper context)
Cut lemons in half and squeeze lemon juice onto rusted surface.
Add generous dollop of salt onto wet surface.
Use a sliced lemon half like a scrub brush. Scrub on rust spots in a circle, using salt as the abrasive cleaner. The messier the better. The acidity of the lemon + the abrasiveness of the salt is the perfect combination to dissolve rust; it’s like magic!
Scrub rust spots until they’re completely dissolved. Periodically check your work by wiping off a section to see if the rust is gone. Repeat all over until the rust is completely gone.
Wipe off the lemon + salt combo by using a slightly damp rag until it’s all removed. Pat yourself on the back, your work is almost done.
OPTIONAL: pour a small amount of olive oil onto clean surface and rub into surface until completely absorbed. Repeat until cast iron is nice and shiny.
BOOM. You’re a rust slayer. How do you like them apples?
