Very simple build, that saves shaking filling draining then repeating to rinse a keg.
Step 1: Equiptment and Construction

take your upsidedown beer crate ( i painted mine to stop it soaking up to much water) put hose through the side and up through the bottom attach garden hose watering attachment and fit in base of crate so it is pointing upwards.
Step 2: Done Start Rinsing Your Keg
Adjust garden hose nozzle to spray, put upsidedown keg that needs rinsing over garden hose nozzle, turn garden hose on and off until keg is rinsed.
