Good question. I just asked my son. He is a professional chemist (degree and job!) mixing and cleaning stuff all day. He says they use a product called alcojet for their glassware dishwasher - and alconox for hand washing some glassware.
Google these words and you you will find several sources and much more information.
I have been using 91% isopropyl alcohol. But that changes tomorrow when he brings me some of this stuff home.
He is filled with chemistry knowledge and can do hard math on a small note pad. He just refused to
vape. (Darn non smoker...)
