The pipe cleaning kit brushes will clean that pipe fast with about 20 drops of Mile HIGH Cleaner. Warm it under hot water or put it in a cup of hot water to get the resin gooey. Choose the right sized brush for the main tubes, remove from water, add about 4-5 drops to the brush and scrub. For the bowls and bowl holder area It looks like the #3 size brush should be bent at the tip to create a "fan end" brush to reach the corners. This Grinder Cleaning Video shows the basic bend on a #2 brush. It can go tighter using plyers to pinch it closed. Then just wash with dish detergent. Once you get good at it, this pipe should not take more than 2 minutes to clean. but the first time has a learning curve. Best with moist warm resin but do not dilute with water.
