Thanks Allen. That was the same result I got, but when I saw it was the
vaporizer, looked no further since I had been to their site before and
did not realize they added the strips. The rest of the hits were oxalic
acid and other strips.

They look like some combo of oxalic acid, sugar (?) and a binding agent,
like a cloth strip. Interesting that they are reusable and cost about $1
US per strip. I am sure someone will try to duplicate them at home, but
Oxalic Acid is tricky in the range of concentrations where it is
effective. So it can do harm or be ineffective, depending on the
concentration.

The original question that generated this thread was if there was any
data on them. Is there?
