Anna-Catherine,
The only good it would do is having really clean chisels. It isn't going to make them any sharper. In fact, the abrasion of the micro-bubbles that do the actual cleaning might dull the edge a bit. Any debris capable of interfering with the chisels performance should have been removed by the sharpening process anyway. If I was concerned about chisel cleanliness, for example, because I had been working green wood, I would use Simple Green, Formula 409, or a commercial resin and pitch remover.
