What You’ll Need
- Chainmail scrubber cast iron
- Cast iron skillet cleaning brush stainless steel
- Stiff nylon scrubber for cast iron cookware
- Cast iron pan cleaning sponge non scratch
- Cast iron seasoning and cleaning kit
Before You Start
Prepare a clean workspace and have towels or paper towels handy. Ensure the pan is cool enough to handle safely. Avoid soaking cast iron in water for extended periods, which can promote rust. If the pan is very dirty, soak briefly in warm water with minimal soap; rinse thoroughly and dry completely. Time estimate: 5–15 minutes for routine cleaning; longer if reseasoning is needed.
Step-By-Step: How To Clean Cast Iron
- Allow the pan to cool after cooking, then wipe away loose food with a dry cloth or paper towel.
- Rinse under warm water, using a small amount of mild soap if desired, though most cleaning is done without soap.
- Choose a cleaning tool: chainmail scrubber, stainless steel brush, or stiff nylon scrubber, based on residue.
- Gently scrub the interior in a circular motion to lift stuck-on bits without removing too much seasoning.
- For stubborn residue, add a pinch of coarse salt and scrub with a damp rag or sponge to act as an abrasive.
- Rinse thoroughly to remove all particles and dry immediately with a towel.
- Place the pan on a warm burner or in a low oven to ensure complete drying and prevent rust.
- Once dry, apply a thin layer of oil to the interior and interior sides, then wipe off any excess with a clean cloth.
- Store in a dry place. If you notice dull spots or rust, reseason following a dedicated kit or guide.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Food sticks frequently | Seasoning is worn or uneven | Re-season surface with oil and bake; repeat as needed | Maintain light oil after each use |
| Rust appears | Pan wasn’t dried thoroughly | Remove rust with steel wool, reseason | Dry completely after washing |
| Residue won’t budge | Stuck-on bits and heavy buildup | Use chainmail scrubber or salt method | Avoid soaking; clean soon after cooking |
| Soap smell lingers | Excessive soap residue | Rinse well, re-oil lightly | Prefer non-soap cleaning for routine care |
Common Mistakes
- Over-washing with soap, which can strip the seasoning.
- Letting cast iron soak in water for long periods.
- Using metal tools that scratch the surface excessively.
- Forgetting to dry thoroughly before storing.
- Skipping reseasoning after cleaning or if rust appears.
Tips For Best Results
- Maintain a light, even layer of oil after every cleaning to preserve the seasoning.
- Choose the right scrubber based on the pan’s condition: chainmail for heavy buildup, nylon for light residue.
- A stiff brush or salt scrub can help without removing seasoning if used gently.
- Always dry the pan completely, then heat briefly to ensure moisture is gone before storing.
- Store in a dry area with a small amount of oil on the surface to prevent rust.
Call A Professional
Contact a professional if the pan has extensive rust that cannot be sanded away safely, or if the pan shows structural damage such as cracks or warping. Seek help if you are unsure about reseasoning techniques or if the cookware is a valuable antique with unclear provenance.

Buying Guide
When buying cast iron cleaning tools and accessories, consider the following factors to ensure the best care for your pans:
Size and compatibility: Choose scrubbers and brushes that fit the interior surface of your pans. A compact brush works for small skillets, while larger chainmail scrubbers suit bigger pots.
Material and abrasiveness: Stainless steel brushes offer strong cleaning but may wear seasoning if used aggressively. Nylon brushes are gentler and suitable for routine maintenance.
Effectiveness with residue: Look for tools designed to lift stuck-on bits without harsh scrubbing. Salt-based cleaning methods can complement tools for stubborn residue.
Cleaning kit contents: A seasoning and cleaning kit often includes oil, cloths, and a reseasoning guide—handy for beginners and frequent users.
Durability and durability care: Stainless steel and chainmail options tend to last longer but require proper drying to prevent rust.
Storage and convenience: Consider compact tools for small kitchens and tools with no sharp edges to minimize damage to cabinets.
Cost vs value: Invest in a few high-quality tools rather than many low-quality items to reduce replacement needs and improve results.
Usage scenarios: For seasoned pans, tools that preserve the seasoning are preferable; for rusty or neglected pans, more aggressive options may be necessary—follow with proper reseasoning.
