Hi everyone,
New here. I need some help identifying a chemical reaction that is causing one hand to be persistently purple. Relevant points:
1. It started what I was using a blue scotch brite sponge dipped in water and white vinegar to clean chalk off a board.
2. The pan is a roasting pan maybe several decades old.
3. The purple is a bright purple that only appears where my hand touched the sponge.
4. I can scrub it off to some degree, bu the weird part is that it will return and get more intense over the course of a day. It will even return under my finger nails.
5. It does not stain pastic.
Questions: Is this some sort of metal compound from the pan that has gotten deeper into my skin than I would like? Are any metal compounds bright purple? Is this an acid sensitive dye from the blue sponge? Any thoughts on the health effects?
Thanks.

Instead of that sponge, try something else.
What kind of pan is it? Most of them are aluminum or steel and some are copper.

I have seen purple stains on (in) skin of people who work with gold solutions (gold chloride). It was due to formation of colloidal gold particles.
