I've noticed that newsprint that has been wetted , then dried, burns
much better. Why is that?
I've asked Cecil and haven't heard yet.

Adding moisture (water) and then removing moisture leaves the newsprint
in a dryer state than it was before it got wet. -Dave

That sees the surface much rougher at a microscopic level than before you do
that.

I don't know about the other response regarding it being drier afterwards,
but I suspect part of it has to do with the structure of the paper being
disrupted from swelling and then shrinking. That would increase the
surface area, and produce lots of small, fine slivers sticking up instead
of a smooth, dense surface.
