The OP did mention "pint bottle". Overall, it can be
done safely. But, the news papers on the floor don't
much impress me.

All correct. A little on a swab is probably not going to do anything
at all. At a minimum though, I'd have a window open. To avoid
spills, go outside and pour off some into a small container of a few
ounces instead of the quart or gallon he is now using. Be careful
where you store it too.
