Lodge Rust Eraser, One Size, Black

This rust-removing block is a game-changer for cast iron. It effectively tackles surface rust without harming your pan's seasoning, provided you use it carefully. I've used it on everything from minor blemishes to more stubborn rust spots, and it consistently clears them up quickly with minimal pressure. Think of it as a precise, satisfying "eraser" for your skillet. What truly sets this block apart is its simplicity and mess-free application. A few scrubs, a quick rinse, and a little re-seasoning, and your pans will look almost new. Plus, it's incredibly durable; I've used it on several pans and Dutch ovens, and it's still going strong. If you own cast iron cookware, especially Lodge, this inexpensive tool is a smart investment. It saves time, protects your cookware, and is far easier to use than abrasive steel wool or wire brushes. I highly recommend it!

Worked better than I thought it would. Faster than the methods I was using before. Will still need some clean up but could cook in them if I wanted to now. I cleaned 2 of my cast irons, and it cleaned up the rust pretty nicely. I still have quit a bit of the bar left so plan on using it on some of my other pots.

Works really well on minor rust area of my cast iron skillet and my Brookstone grill top. Wears out pretty fast if you use it a lot of course.

I was skeptical at first, but the Lodge Cast Iron Rust Eraser completely won me over. I used it to revive a vintage skillet that had been sitting in my garage for years, and it worked like a charm. The eraser is easy to grip and gives you precise control, making it perfect for targeting rust spots without damaging the rest of the pan. It strips rust down to the bare iron, so yes—you’ll need to re-season afterward—but the results are totally worth it. My skillet looks brand new and cooks beautifully again. I’ve even used it on grill grates and old tools with great success. For such a compact tool, it packs serious power and is incredibly durable. Plus, it’s made in the USA, which is always a bonus. If you’re into cast iron cooking or restoring heirloom pieces, this eraser is an absolute essential. Highly recommend for anyone who wants to keep their cast iron in top shape without harsh chemicals or endless scrubbing!

This thing works so good we had to google what it’s actually made of. Works on rust very well!

This is an amazing tool. I had several, severely rusted, cast iron pans and was planning to throw them out. I thought this eraser would be an inexpensive last option to saving the pans. It worked. I followed the directions to use on a dry pan, wash in warm, soapy water, dry and then re-season. I highly recommend this tool for removing rust.

I don't know why this works. I don't. It feels like rubber and I'm seeing little specs of metal mixed within it, but...IT WORKS. BUY THIS NOW. I had a 14 inch cast iron pan that my mother accidentally ruined years ago (read: like 5ish years) and I was about to throw it away during a new year clean out, but then I decided to "fix it" as a hobby. I tried the potato and salt method, soaking in vinegar, scrubbing with a steel wool and dish detergent and salt and....just, so many different methods and practices. So many. They would helped a little, but there was still rust, over and over and over. So I thought, as a last ditch effort, to pick this up. It was inexpensive and by a reputable brand that is incredibly well known. If I were to purchase another cast iron pan, I could use it for that if I needed to. I started scrubbing the edges and interior of my pan and...it was working. It was removing the rust that I had consistently been unable to remove by the tons of other methods. I didn't require a cleaner (at least not initially), or salt, or vinegar. Just the power of this bar and a small bit of elbow grease. After I shook out the rust dust, I washed it with a little bit of Dawn and a sponge with a nylon scrubber on one of the sides. I then seasoned it (450F for 60 minutes, then just turn the oven off and let the pan cool down in there). It is perfect. There's still some discoloration, BUT the rust is GONE. VANISHED. ELIMINATED. This is pure Witchcraft, no other excuse. lol

I tried this out as soon as I got it. I searched. YouTube for video demos and found one. I followed his directions and found it works best on very light rust (called ‘flash rust’) and not so well on moderately or heavily rusted surfaces. It’s similar to an eraser in that it leaves behind gritty stuff you’ll need to sipe out before using the pan. I dumped out what I could and wiped out the rest with a paper towel with avocado oil on it. After I got it all out, I heated the pan to try to re-season it and it was nicely black again. This product is most suited to small projects without a lot of surface area. It takes a little elbow grease but it’s not hard to use. It wears down pretty quickly with use so you’ll want to do small areas at a time.
