I’ve read posts with people having to clean or have plugged cooling tubes or rails. It’s actually one of the things I do for a living.
Water jetting. Very easy, effective and fast. Basically you are pressure washing the inside of the pipe. This video will give you an idea. For those of you with a pressure washer, all you need at the end of your hose is a jet head of which is reasonably affordable. Some of you may even be able to make it yourself.
Take care,
