how to remove ferric chloride from natural wool carpet

[GreyWoolfe]

I'm glad my office/workshop floor is concrete.  Doesn't matter to me if I get a stain on it, no one comes in my space.  I'v never spilled it on the floor though, even when I had an apartment.  I've spilled it on the work surface for sure.  The stains add character.

I think I'd forget about trying to getting rid of the staining. It'd be almost impossible. I remember walking dog sh** into a wool carpet once and even after professional cleaning you could still see a brown patch

The easiest thing now would be to spill it on the rest of the carpet too so it all looks the same ;-)

Black paint. Works every time.

Or scissors.

Wouldn't a 12 gauge be quicker?

Deny everything.  Make counter-accusations.

If successful,  become a politician.

Accuse the dog.

Check and see if the French Foreign Legion will take you.

It is like the perfect storm.  Few stains are worse than ferric chloride, and few things are easier to stain than natural wool carpet.   

I can add a couple of warnings from personal experience...

1) Never try to stand on your head right next to a big glass window NOT made of safety glass.
2) Never try to examine a black vinyl record with a strong magnifying glass under a very strong light.

We probably all have similar personal warnings we could add.

I've done the plate glass thing.  Although, I didn't even know it was closed as it was recently cleaned.

You could always spot up the entire carpet with FeCl3 and call it a room remodel by accident.
