My black tank valve is stuck. Easy lube fix?
For sometime the black tank valve handle has been becoming increasingly difficult to open and close. Now it’s game on. It is next to impossible to close once opened. Is there a simple lubricant fix...

Replace it. No, it's not a fun job, but it's time. There's nothing you can put in the tank itself that will help- with the exception of a lot of water to flush it out before you tackle this job.
