If it's like the stuff sold in the US, it'll be around a 5% acidity level.
That's fairly safe. Near as I can tell, the Swedes have some use for vinegar
at higher concentrations. I can get 24% vinegar at the Korean market - my
guess is that you don't want to get that stuff on your skin. I was surprised
that she called vinegar "acetic acid." She used to work in a lab so maybe
that's the reason.

My guess is that Sarson malt vinegar is not diluted acetic acid but beer
that is allowed to turn. My step-mom is looking for for something completely
flavorless so diluted industrial acetic acid might be her cup of tea.

I don't know about acidity stuff, I just know I like it and yes, it did
clean old coins)

We do have white (Sarsen's) vinegar here but it isn't something I use much.
