Haven't seen how it works but my kegs come out clean. As mentioned in another review, you should be aware of some residual chips. On two separate occasions when I shut off the pump there were a few pieces that barely slipped through the atomizer holes and I had to pry them out with a small pair of tweezers. A few of them sank to the bottom of my mop bucket and I could easily see and pick them out. The high pressure pump may need to be flushed outdoors before performing a recirculation flush to avoid the risk of chips entering the pump. Otherwise I think it's a great accessory! I would buy this again. Just be careful
