Sorry if I missed it, but I have searched on removing spin racks and haven't found anything. Feels like a dumb question but I am not really sure how to remove the rack. I removed the 4 allen bolts, one side of the clamp pulls away, but the other side which is the rack and spin itself is firmly planted to the tower. Am I missing something or does it take some force to remove. I just want to take them off to make it easier to clean. They are not that bad, am I better just leaving them on the tower?
