Steel wool is an all-purpose material with countless applications in and around the home, from cleaning and restoration to home improvement and even survival skills. In this guide, we explore 10 innovative uses for steel wool and give tips on how to use it safely and effectively.
Steel Wool Grades
Steel wool is graded based on the thickness of its fibers, ranging from super fine to extra coarse. The grading system uses numbers, with higher numbers indicating coarse wool:
- 0000 (4/0): Ultrafine
- 000 (3/0): Extra fine
- 00 (2/0): Very fine
- 0: Fine
- 1: Medium
- 2: Medium coarse
- 3: Coarse
- 4: Extra coarse
Choosing the right grade of steel wool for your specific project helps you get the desired results without damaging the surface you’re working on. Here are some general guidelines:
- Use finer grades (#0000 through #0) for delicate surfaces and polishing tasks.
- Medium grades (#1 and #2) are suitable for general cleaning and paint preparation.
- Coarser grades (#3 and #4) are best for heavy-duty cleaning and rust removal.
Household Cleaning and Maintenance
Steel wool’s abrasive nature makes it great for various cleaning tasks around the home. Here are two common applications:
1. Reviving Aluminum Surfaces
Over time, aluminum surfaces can become dull and oxidized. Steel wool can help restore their original shine. To revive aluminum surfaces:
- Choose a fine-grade steel wool.
- Gently buff the aluminum surface in a circular motion.
- Wipe away any residue with a clean cloth.
- Polish the surface with a metal polish for added shine.
Important: Be careful which metals you use steel wool on. On stainless steel surfaces, steel wool will fray and leave behind tiny bits that rust, actually making things worse. For stainless, use a synthetic scrub pad instead, and rub only in the direction of the grain, never across it. Then rinse completely and towel dry.
2. Removing Scuff Marks From Floors
Steel wool can effectively remove stubborn scuff marks from vinyl and linoleum flooring without damaging the surface. To remove scuff marks:
- Dampen a piece of fine-grade steel wool with water.
- Gently rub the scuff mark in a circular motion.
- Wipe the area clean with a damp cloth.
- Dry the floor thoroughly to prevent water damage.
Pro Tip: Flooring finisher Peter Egan, featured in TOH Magazine, uses #00 steel wool for delicate floor work. When removing paint drips from polyurethane-finished hardwood, he dips fine steel wool in denatured alcohol and scrubs lightly. “You can’t do this with a machine because you’ll go right through the finish,” he says. Before the solvent can soak into the wood, he dries the floor with a quick wipe using a cotton rag.
Woodworking and Furniture Restoration
Steel wool is a valuable tool in woodworking and furniture restoration projects. Here are two creative uses:
3. Creating an Ebonizing Wood Stain
You can create a natural, ebony-like stain for wood using steel wool and vinegar. This technique is popular among woodworkers, including This Old House contributor Joe Hurst-Wajszczuk, for achieving a rich and dark finish. To make the stain:
- Place steel wool in a glass jar.
- Cover the steel wool with white vinegar.
- Let the mixture sit for 24–48 hours.
- Apply the resulting liquid to the wood using a brush or cloth.
Pro Tip: You can also use rusty nails or other rusty steel parts in place of steel wool — the key ingredient is the iron reacting with vinegar to form iron acetate. A TOH-tested variation calls for mixing 1/4 cup of rusty nails with 3/4 cup of vinegar and letting it steep for 24 hours for a similar aging effect.
For best results, pour the liquid through a coffee filter before applying to remove any steel wool particles. Iron acetate reacts chemically with the tannins in the wood, so this technique works especially well on tannin-rich species like oak. One coat is often all it takes to give oak a dark cast. Sand the surface until it’s the shade you want, then apply a protective coat or two of shellac or water-based polyurethane.
4. Deglossing Paint for a Matte Finish
You can use steel wool to reduce the sheen of glossy paint, creating a more matte finish. This technique is useful when you want to change the appearance of a painted surface without repainting. To degloss paint:
- Choose the finest grade of steel wool.
- Gently buff the painted surface in a circular motion.
- Wipe away any residue with a tack cloth.
- Clean the surface with a damp cloth and let it dry.
Home Improvement and Repairs
Steel wool can be a handy tool for various home improvement tasks and quick fixes. Here are two practical applications:
5. Securing Loose Screws
TOH master carpenter Norm Abram finds that steel wool tucked into an oversize hole can keep its screw secure after that last turn. To secure a loose screw:
- Remove the screw from the hole.
- Pack a small amount of steel wool into the hole.
- Reinsert the screw, turning it slowly.
- The steel wool will compress and grip the screw, holding it securely in place.
6. Blocking Rodent Entry Points
Steel wool is an effective barrier against rodents since they can’t chew through the metal fibers. To use steel wool for pest control:
- Identify potential entry points around pipes, vents, or small gaps.
- Cut a piece of coarse steel wool slightly larger than the opening.
- Pack the steel wool tightly into the gap.
- Seal the area with caulk or expanding foam for added protection.
Pro Tip: TOH’s pest-control experts recommend using copper mesh or bronze wool instead of steel wool for blocking rodent entry points. As noted in This Old House Magazine, steel wool rusts over time, which can compromise the seal. Copper mesh resists corrosion and stops mice cold when they try to chew through it. For a belt-and-suspenders approach, stuff the mesh into the gap, then seal over it with caulk or expanding foam.
Outdoor and Survival Skills
Steel wool’s unique properties make it useful in outdoor and survival situations. Here are two unconventional uses:
7. Starting a Campfire With Steel Wool
In emergencies, you can use steel wool to start a fire when traditional methods aren’t available. To start a fire with steel wool:
- Stretch out a small amount of fine-grade steel wool.
- Touch the terminals of a 9-volt battery to the steel wool.
- The electrical current will cause the steel wool to spark and ignite.
- Quickly transfer the burning steel wool to your tinder bundle.
8. Rust Removal on Outdoor Equipment
Steel wool is excellent for removing rust from metal surfaces, making it useful for maintaining outdoor equipment. To remove rust:
- Choose a coarse grade of steel wool.
- Rub the rusted area vigorously with the steel wool.
- For stubborn rust, use a rust remover solution in conjunction with the steel wool.
- Clean the surface with a damp cloth and dry thoroughly.
- Apply a rust-inhibiting primer or paint to prevent future corrosion.
Unconventional Uses for Steel Wool
Steel wool’s versatility extends to some surprising applications. Here are two unique uses:
9. Muffling Motorcycle Noise
Some motorcycle enthusiasts use steel wool to reduce exhaust noise. While this isn’t a recommended long-term solution, it can be effective for temporary noise reduction. International Steel Wool’s Eric Bonn tells auto-buff clients to try these steps to muffle motorcycle noise:
- Use stainless steel wool to avoid rusting.
- Carefully pack the steel wool into the muffler can.
- Make sure the steel wool is secure and won’t be expelled during motorcycle operation.
Pro Tip: Eric Bonn, sales manager at International Steel Wool, recommends using stainless #3 grade steel wool to pack the muffler can for cutting motorcycle noise. The stainless variety resists the high heat and moisture inside the exhaust system far better than standard steel wool.
10. Preventing Pet Hair Clogs in Drains
You can even use steel wool as a temporary hair catcher when bathing your pets. To prevent clogs:
- Loosely stuff a small amount of steel wool into the drain.
- Bathe your pet as usual.
- Remove the steel wool after bathing, along with any trapped hair.
- Dispose of the used steel wool properly.
