Rather than making a big mess trying to cut a roll of paper towels in half as most instructions suggest, I took a tall container such as the "Club Mix" container from Costco. A regular-size roll of paper towels fits in this perfectly. Then fill it about a third full of plain, undiluted white vinegar. Let it sit for about three days and the roll of towels will soak up the vinegar and so will the inner cardboard.
