A Hunker report points to a $24.98 DeWalt knotted wire brush sold by Lowe’s as one option for removing paint and rust from metal outdoor furniture. The report cites an average 4.9 out of 5 rating from 85 users, while warning that the aggressive brush can smear heated paint, leave a rough finish and pose safety risks.
A Hunker report has highlighted Lowe’s $24.98 DeWalt 3-inch knotted angle-grinder brush as a possible tool for stripping old metal outdoor chairs, drawing on a restoration project shared by Tammy and Ron Young. The attachment had a 4.9 out of 5 rating from 85 users in the report, but the couple’s experience and the tool’s limitations suggest it may not suit every paint-removal job.
The DeWalt product is a knotted wire-brush attachment, not a bench grinder. According to Hunker, it works with a 3-inch angle grinder with a 5/8-inch arbor. Knotted bristles are bundled together, making the brush more aggressive than a standard crimped wire brush, whose bristles are left more flexible. The report says knotted brushes are commonly used to remove rust and prepare metal for welding, as well as for heavy-duty cleaning on materials including concrete, masonry and wood.
Tammy and Ron Young described using a knotted brush to strip paint from metal lawn chairs before repainting them in a post to the Facebook group “Metal Lawn Chair Restorers, Artists, and Aficionados, United.” Hunker reported that the method produced acceptable results, but was not ideal: the friction generated enough heat to soften and smear paint across the chairs. The couple said they would have preferred sandblasting, but found it too expensive. They also found the knotted brush lasted longer than the “blue pads” they had tried; Hunker suggested those pads may have been zirconia flap discs.
The product’s rating and price are details reported by Hunker, not a guarantee of performance on a particular chair or surface. The source does not say when the price or rating was checked, and both can change. For shoppers, the practical takeaway is to weigh the brush’s fast, aggressive action against the finish required and the furniture’s material and shape.
A Fast Stripping Tool With Limits
For people restoring painted metal patio furniture, the attachment offers a relatively low-cost alternative to professional blasting, particularly when the job involves rust or stubborn coatings. Its aggressive action can remove material quickly, but it can also create extra finishing work. Hunker says the brush may leave a rough, textured surface that requires sanding, polishing or a less aggressive crimped brush afterward.
Its stiffness also affects where it works well. A knotted brush may not follow curved or contoured chair parts as closely as a more flexible brush, and it may miss paint in corners. Those are general limitations noted in the report; Tammy and Ron did not say whether they encountered them. The distinction matters because a tool that works on broad, flat metal sections may be less effective on detailed furniture.
Material compatibility and personal safety are also central to the decision. Hunker warns against using a carbon-steel-bristle brush on aluminum or stainless steel because it can cause corrosion. High-speed brushing can throw sparks and eject fragments of paint or metal, so eye protection is essential. Buyers should check the product instructions and their grinder’s compatibility, and avoid assuming that a high user rating means the brush is suitable for every refurbishment.

How the Chair Restoration Went
The product came to attention through a DIY furniture-restoration example, rather than a new product launch or a change in Lowe’s policy. Tammy and Ron Young shared their approach in a Facebook group focused on metal lawn chairs. Hunker connected that project to the DeWalt attachment listed at Lowe’s and described the attachment’s reported price and user rating.
Wire brushes differ in how their bristles are arranged and how aggressively they contact a surface. Hunker says a knotted brush removes material more aggressively than a crimped brush, which is generally more flexible. The report says crimped wire wheels are more commonly recommended for DIY paint removal. It also cautions that knotted brushes may be a poor choice for stripping paint from wood. These are general tool-selection points, not claims that every surface or paint will react in the same way.
The Youngs’ account offers a specific example, not a controlled comparison of tools. They wanted to clear paint before repainting the chairs and continued with the knotted brush despite the paint smearing. Their experience suggests the method can be workable, but also shows why surface preparation and the desired final finish matter as much as removal speed.
“They would have preferred to sandblast the chairs, but it was too expensive.”

Price, Fit and Finish Questions
The report does not provide a date for the Lowe’s price or the product rating, so it is unclear whether the $24.98 price and 85-review rating count remain current. It also does not identify the exact paint, chair condition, grinder speed or working technique used by the Youngs. Those details could affect how quickly paint softens, whether it smears and how much finishing work is needed.
There is no independent test in the source comparing this DeWalt brush with a crimped brush, sanding, or sandblasting. The report does not establish that the product will remove every coating effectively, nor that it is appropriate for every metal or furniture design. Its warning about carbon steel applies especially to aluminum and stainless steel, while paint and surface condition vary. Readers should consult the product and grinder instructions and select a tool compatible with the workpiece.
Check Compatibility Before Use
Anyone considering the attachment should first verify that their angle grinder accepts a 3-inch brush with a 5/8-inch arbor, then check the current listing for price, rating and product instructions. They should identify the furniture’s base metal and avoid carbon-steel bristles on aluminum or stainless steel, as Hunker warns that this can cause corrosion.
Before working, wear eye protection and follow the grinder and brush makers’ safety directions; sparks and flying fragments are possible. Test the method cautiously on a small, inconspicuous area where appropriate, and plan for a less aggressive finishing step if the brush leaves the surface rough. The report does not describe a follow-up project or a new product announcement, so the next useful information for shoppers is whether Lowe’s listing and the user rating have changed.
Key Questions
Is the Lowe’s DeWalt product a bench grinder?
No. Hunker describes it as a 3-inch knotted wire-brush attachment for an angle grinder with a 5/8-inch arbor.
Can a knotted wire brush remove paint from outdoor chairs?
It can remove paint from metal, according to Hunker, but Tammy and Ron Young reported that heat from brushing softened and smeared the paint on their chairs. The tool may also leave a rough surface that needs further finishing.
What surfaces should not be brushed with this carbon-steel attachment?
Hunker warns against using a carbon-steel-bristle brush on aluminum or stainless steel, because it can cause corrosion. Check the product instructions and confirm the furniture’s material before use.
What safety precautions does the report recommend?
Wear eye protection. A high-speed brush can produce sparks and eject small pieces of paint and metal. Follow the angle grinder and brush manufacturers’ safety instructions.
Is the reported $24.98 price guaranteed to be current?
No. Hunker reported a price of $24.98, but the source does not state when it was checked. Lowe’s price and the product’s review count or rating may change.
