I'm not sure this would work but you could use some heater hose from your local auto parts store. Heater hose is ment to hold coolant as it transfers hot coolant to your heater core or transfers coolant anywhere really. I would recommend trying that as its decently cheap, like a dollar a foot. As for spraying the coolant off, I wouldn't directly put water on the engine because you don't want water getting into anything electrical. You could mist it then wipe it all off with a microfiber towel.
