Hydrochloric acid (30% - BE CAREFUL) will strip the chrome at room temperature but not the chomium oxide interfcial material which can be removed using HF. Various additives are used with the HCl they are mostly wetting agents.

How can you strip off the Chrome from the glass?
In my experience, it comes off by polishing with pich or by grinding. I have not find any soultion which solves the Cr underlayer.

For Al and Ag I deposit 300 A Cr underlayer on glass at 20 A/s . Before
I make oxygen ion beam substrates pre-cleaning during 2-3 min.
Everything looks fine, adhesion is very good.
