Radiator cleaning tools?

Hey guys i’m posting here since I know this forum has a lot more knowledge than some others, I have a hard time washing out the radiator on the wolverine and i’m planning a trip to Brimstone in about a month and I want to be able to clean it out once I get there seeing as I know it will probably get dirty there and i’ll be in a pinch. I have seen the radiator genie but I refuse to pay 50 bucks for a garden hose adaptor and didn’t know if anyone else had made anything similiar to it or copied it? Odd question but its worth a shot! Thanks guys! :rocker:
