What's in a Swiffer Cloth?

I think a Swiffer would work great for the dog hair around here, but I’m too cheap to pay for the cloths. Seems like there must be something I can spray on a paper towel… anyone know what’s in 'em?

There is nothing in them. It is the fabric that they are made of it is like really fluffed out cotton balls. They are not that expensive anyways I got a set of 8 hand held ones for less than $5 and one of them will dust my 2 bedroom apt twice.
