Okay, so I finally got my hands on one of these laser rust cleaning machines. Been curious about them for ages, seeing videos online and wondering if they really worked as well as they looked. Decided to bite the bullet and try one out myself for the workshop.

Getting Started

Pulled this thing out of the box. It was pretty straightforward, honestly. Had the main unit, the laser head thingy which felt surprisingly solid, and some cables. Plugged everything in where it seemed to go. The instructions were okay, not great, but good enough to figure out the basics. Had to put on the special safety glasses they included – seriously, don't skip this step, the laser light is no joke.

First thing was just figuring out the controls. A few knobs and buttons. Looked a bit intimidating at first, but it was mostly about setting power levels and maybe the scan width, stuff like that. I decided to start low and slow.

First Try - Some Old Tools

I grabbed an old, really rusty wrench that's been sitting in a damp corner forever. Perfect test subject. Turned the machine on, fan kicked in, sounded like a serious piece of kit. Pointed the laser head at the rusty part, maybe held it a few inches away, and pulled the trigger.

Wow. Okay, it actually works. You hear this sort of crackling, zapping sound, and you see tiny sparks. The rust literally just… disappeared. Vaporized, I guess. Underneath was bare metal, looking almost new. It was pretty amazing to watch. I played around with the settings a bit, turning the power up slightly, moving the head faster or slower. Faster movement needed a bit more power to get the same clean effect.

• Started with low power – slow cleaning but safe.
• Increased power – much faster rust removal.
• Adjusted scan width – could cover bigger areas or focus on small spots.
• Key thing: Finding the right distance and speed took a minute of practice.

Tackling a Bigger Job

After messing with small stuff, I decided to try it on something bigger. Had this old metal garden gate section that was just covered in surface rust. Sanding that thing would take forever and make a huge mess. So, I wheeled the machine over.

This took a while longer, obviously. It's not like waving a magic wand over a huge area instantly cleans it. You have to go section by section, methodically. I found a rhythm, sweeping the laser back and forth. It did heat up the metal a bit, nothing crazy but definitely warm to the touch afterwards.

The result? Honestly impressive. It stripped the rust right off, leaving clean metal behind. It got into the nooks and crannies that would be a real pain with a wire brush or sandpaper. There was hardly any mess, just a faint smell in the air, kind of like ozone or burnt dust. Way cleaner than traditional methods.

Some Thoughts After Using It

It's definitely cool technology. And it works really well on surface rust. Deeply pitted rust took a bit more effort, sometimes needing a couple of passes. It didn't seem to damage the underlying metal when I used the right settings, which was a big plus compared to grinding.

Downsides? Well, the initial cost isn't cheap, obviously. And you absolutely need those safety glasses. Also, it's not instant for large areas; it still takes time and patience. You have to keep moving the head consistently. Oh, and the fan noise is noticeable, not deafening, but it's there.

Overall, I'm pretty happy I got to try this out. It's a fantastic tool for specific jobs, especially delicate parts or complex shapes where sanding is tough. It made short work of that rusty wrench and saved me a ton of hassle on the gate section. Definitely keeping this thing handy in the workshop.
