The very end of the brass nozzle unscrews easily. Just make sure to keep track of the order that the plastic and rubber parts go in, and which way they face. It's not all that intuitive.
Should be easy to clean if the valve is clogged. If you have sealant deeper into the tube, then you're probably due for a new gauge. I'd say these are far easier to clean than any digital gauge.
