OMG!! I haven't seen that for decades!! That, dear sir, is a case a
Steezles!

Not unlike measles in humans. It usually happens with imported steel, that has been in shipping containers aboard ship for extended time frames. The dark, warm, moist environment encourages it's spread, and if not handled promptly, it can wipe out an entire generation of steel! Also, it is highly contagious! Make sure the steel, or anyone who's handled it does not come into contact with outside steel.
Treating it isn't difficult....but requires extreme care. Latex or nitrile gloves, a cleaning solution of windex, alcohol, or in severe cases, acetone. First, any cleanly cut surfaces should be sanded to a clean smooth finish. Aftward, decontaminate the area with any of the products listed in the last sentence. Dry well. The ONLY way to see if your decontamination efforts worked, is to dip the cleaned ends of the steel in ferric chloride, or your chosen etchant...... if those
Steezles spots show up, your steel is still infected.....repeat your decontamination steps, and check again. If the spots do not shop up, then you successfully decontaminated those particular pieces. (good job!)
The big issue with
Steezles is that you can never be certain you eradicated the disease. Proper shop and steel hygiene is a must to keep it under control. In the end it's really nothing to panic about, because it's rarely fatal to humans.

How's that for a Saturday morning funny? I thought it was pretty good.
