graphic papers (for printing) will contain clay as it's made and in coating
after it is made, it most likely will have calcium carbonate to combat acid
degradation over time of the wood fibers and for brightness, titanium
dioxide is also used for opacity and brightness. All 3 of these "pigments"
are abrasive clay the least, Ti02 the most. There are all kinds of graphic
papers that may or may not contain these pigments, may or may not be
precoated, top coated, and calanderd. I would not use any paper to make
strips for cleaning leaf contacts once wet is likely to "shed" all kinds of
stuff. Plain uncolored card stock is ideal with no pigments, heavy and
stiff and not wilt when soaked with IPA, I use those tags with a string
attached for IDing stuff, easy to cut thin strips, soak with IPA, slide
under open leaf and then close to "lock" the strip as I pull it out to
scrub the contact surface, firm but gentil

why paper wouldn't be recommended
Generally, paper vendors ... like for copiers, or laser printers... won't
tell you what is in their paper, or what is on the surface of their paper.
At least, they won't tell me.
AFAIK... and at least... a lot of paper... has 'clay' as a binder... and,
'ink jet printer paper' may be 'coated' with some kinds of 'clay'
Of course this 'clay' ... whether used as a binder, in the paper... or as
an ink 'stabilizer' ... when coated on the surface of the paper... is a
highly refined material.
Yet... just by the vary nature of the minerals that clay is composed of...
there is an abrasive content.
Does that content, significantly abraid the gold on contacts.
Who knows?
