Default Cleaning the PCV Valve without removal?

I have a GSR and everything I've read says that it's really hard to get to the valve to remove. I was wondering, is it possible to remove the other end of the tube and spray WD-40 in there to improve the performance of the valve? As in, you disconnect the tube from the crankcase, spray WD-40 down into the tube, leave the tube up high so that the penetrant reaches the valve, thus cleaning the PCV. What do you think, would it work?

just change it.

no quick fix to clean it - all the junk would go into the black box or the crankcase.

they are under $15 new from a parts store, and take about 30 mins to maneuver in there... if you have the stock intake.

They're hard enough to clean properly off the car so no. Replace the valve.
