Starsan is a combination of acids. It's a food safe sanitizer used regularly in brewing. Here's a link to the MSDS if you want the technical details.It’s very thin and delicate compared to many other wrappers. I like it but it’s really delicate to work with
I’m not sure that the that cleaner you mentioned is what I’m talking about. I want a safe mild acid to bring the leaf closer to 7ph.

I have no idea if its safe to smoke, or what the PH is. It comes in concentrated form and you dilute it down to use for sanitizing equipment. When I brew beer I dilute it at the published rate. There is no need to rinse the acid off after sanitizing is complete.
