Lasers for cleaning metal

[JustinO]

Hey guys,

I've seen the half million dollar industria l rust ablating lasers on youtube:

I was wondering if one could use this on a smaller scale for cleaning very small stuff. I often have to clean small brass parts that are corroded. They have very important textures and shapes, such as fine threads and engraving s. The problems is the oxides are tuffer than the metal, and anything that will remove the corrosion will obliterat e the brass. These lasers would be perfect, were it not for the $$$$$

I only need to clean a pinhead area at a time -- very small stuff.

So I ask you all:
What kind of laser are they using? Wavelengt h etc.

Are there standard Chinese engravers that could remove corrosion on a very small scale?

I've heard of shiny metals ruining lasers, is that an issue for corroded, amorphous lasers?

I'm on a low budget, so combining a CNC laser engraver/cutter with some cleaning would be awesome.

Any help/advice is appreciat ed.

They were all over the news a couple years ago, then pretty much disappear ed.  I found a 100W version on Amazon for only $48K; drop 2 or 3 zeros off the end and it might be affordabl e.

I wonder if they ever sold any of them?
