I agree with the others to just take off the chain and soak/swish around in a jar of Odorless Mineral Spirits. I've used 3 different on-bike cleaners one of them being the Park Cyclone and all were messy, used excessive cleaner/solvent to get the chain clean, were a pain to clean up after use, and in general a PITA compared to popping off the chain, drop in a jar with a couple changes of clean solvent until reasonably clear, wipe down the chain and let dry, install, done. My experience is that the chain cleaners didn't save any time and often took more time. If you use OMS you can save the used spirits in a jar and let the gunk settle to the bottom after a couple days. Pour off the clear spirits into another jar and wipe out the gunk from the bottom and your used spirits can be used over and over again.
