I had the same thing happen to me. I was going to leave it dedicated, but later on decided to cut the tube off. I trimmed it as close as I could get with the scissors, then I took an xacto knife and slowly split the hose left on the airlock till it came off. But I would for sure try the hot water thing first. I have since then upgraded to a dedicated 1 inch blowoff and bucket lid.
