How do I clean and repair the solenoid water valves?

How do I clean and repair the solenoid water valves? I live in an area where the water has a high mineral content. The solenoid valves do not seat and leak. How do I access the valves? Can I dismantle and clean the valves? Are these valves a diaphragm or a spool valve? Can i fet parts or must the valve be replaced as a unit? ANSWERS:
