Depends upon nature of failure.
Solenoid is electrical device with mechanical function.
If you use MultuEcuScan to read failure code it also should be mentioned what exactly not good enough.
If problem is mechanical ( flow pressure, etc ) it worth to clean it.
If problem is electrical ( inner circuit cut which is most popular ) it is not.
For last one it is worth to check socket contacts & wiring before replace.
