I am having a problem with my drag, this is not the time to send it in

what is happening is it is always tight even with the knob off. I took the spool off and the retainer the first ss washer came out but I couldn't get the rest out they are stuck. should I use WD 40 or some type of penetrating oil?
I think they just need a cleaning. I really don't want to send it this week, I have a couple of weeks left before I have to return to work and I am fishing hard.
