I use the Paterson washer. It works well. It depends on print size, how many can be washed at one time. I tend to keep RC prints in a tray of water until I'm finished printing. I then give them 2 mins each in the Paterson unit. It's a simple device that works well. I don't have experience of the other type. Alex
Does the water flow out of the washer trough a hose or trough a series of holes?
