Thanks, that was my thought about paper towels, no sand. Why would
anyone go to the expense?
I don't know about paper towels, but Kimberly-Clark says that their
facial tissues contain "an additive" to make them strong. That
additive does not biodegrade. Because of this they recommend against
flushing facial tissue down the toilet. Their bathroom tissue does
not contain this additive. The additive, which I have heard is white
clay, is abrasive. I've always advised people to use toilet tissue
rather than facial tissues to clean lenses for this reason. It's
possible that paper towels, which need to be stronger than facial
tissues, have more of this additive. White clay is, so far as I
recall, a mixture of silica compounds and titanium dioxide.
For cleaning lenses I use one of the commercial lens cleaners and
Kodak or similar lens tissue.
