Bizzare probe tip etch attempt with KOH

I had heard potassium hydroxide was the electrolyte of choice for etching titanium wires. I tried it on my Nichrome. It is much less ... aggressive. I had to run it at 12V to get anything to etch, and then, well, I bring you The Demon Probe:

Totally unusable, but very eldritch. There's a lot of gnarly corrosion on there that won't boil off.

Conclusion: salt works better for Nichrome wire tips. But I will try to source some titanium wire and see what that does. Anybody got donations?
