Introduction: Refurbish Your Old Wire Brushes

Wire brushes.  How often have you started to pick one up and discovered the bristles no longer point in one direction, but spread out like a 1970s haircut?  Not only that, but if you're like me, you want to avoid this type of brush at all costs, since these wayward wires are very good at penetrating fingers right where the nerves are closest to the skin... Ouch!

Some of my brushes are quite old with short bristles, a testament to their age.  These short-bristled brushes are very handy for reaching into tight spaces, so I try to take good care of them.

If your wire brushes are a little "ratty", try this nifty little trick to bring them back into shape.

Step 1: What You'll Need:

What you'll need:

A ratty wire brush.  (The one I'm using wasn't this abused, but I wrecked it for demonstration purposes.)

A bench grinder with a wire wheel.

Step 2: How It's Done

Run both sides of the brush through the bench grinder's spinning brush and the wheel will "Comb" the wire brushes bristles, straightening them out.  This works just as well for stainless and brass brushes.

Not only will the combing straighten out the bristles, but it will shine them up as well.  Now your brushes can live to be as old as mine.

I hope this helps and saves a few old wire brushes from the trash heap... And a few fingers from multiple tiny puncture wounds:)

but now how do i straighten my wire wheel D:

I love this! I have a favorite brush that I couldn't part with even though it's basically useless. Now I'm so glad I kept it. Thank you!

Thank you yvael. I can't tell you how good your comment makes me feel :)

I like my wire brushes styled like a 70s bush cut. Then they clean at all angles! Mostly I use powered wire wheels like your bench grinder, or my favorite, a cup brush on an angle grinder.

Now here is my hot tip for those. Spend the money and get wire wheels rated beyond the speed you plan on running them. Your cheeks will thank you when you're not pulling broken wires out of them. On my 3450 RPM bench grinder for example I run a 6800 RPM rated wheel. It lasts way longer than a 3450 wheel does, so it ends up costing less than buying 3 or 4 "cheap" wheels do.

GREAT tip pfred2... If I use a really cheap wire wheel and bend my head down while I'm using it, I bet I could get rid of my bald spot:)

I've had ejected wheel wires embed pretty deeply into me. Face shots are the worst but that isn't saying I like gut shots either. When the higher speed wheels fatigue they go, but they kind of go all at once at the end. The cheap wheels seem to start going the day I get them.

I rarely use any wire wheel, as they produce a galled finish. Hand wire brushes, sand paper, diamond paste and Carnauba wax is my preferred pile of cleaning stuff. Also, there's an automotive paint removing brush that uses micro glass fibers and does a phenomenal job of cleaning deep into the corners of small parts and tools.

Often I just remove the heavy material with wire wheels, and finish with other methods. Like much in life I find moderation is the key to success.

I've run into situations where I won't wire wheel something because I don't wish to damage it, but that has been more the exception, rather than the rule for me.

Very clever! Thanks for sharing!

Thank YOU.
