+1 - utter rubbish! I'm not sure why there is so much hate for the park tool chain cleaner. I suspect people are not using it quite right. You do get an oily mess on the floor, but you would anyway using a degreaser. This is combated by spraying the immediate area with a bit of water, that means that you can just brush it away later, rather than getting black oil stains on the floor. It does a great job of making a manky chain shiny again. First pass through with concentrated degreaser, then a diluted pass through, then 3x clean water. Dry with a rag, then leave to air dry before lubing. Love it.
