The side that sticks out farther goes toward the pressure plate.
You replace it. The oil is in the clutch face and if you use it, the face will come off of the disc. There is no way to clean it.
If the disc is installed correctly the clutch will engage and disengage smoothly. In most cases if the disc is installed backwards the clutch disc will bind against the flywheel/crankshaft bolts and not release resulting with a clutch that doesn't disengage. More than likely if the disc was installed backwards the disc is now damaged and will need to be replaced.
It sounds like you have a worn out clutch disc or the pressure plate is not applying enough pressure to the disc. Either way, it does sound like you are ready for a new clutch.
Hold your clutch disc sideways. The middle hub sticks out farther on one side than on the other. The side it's sticking out farthest on goes toward the transmission. Don't worry...if you put it on upside down the pressure plate won't fit, which is your signal to flip the disc over. The important thing is to be sure you have the hole in the clutch disc exactly aligned with the hole in the gland nut...if you don't, the engine won't go back in.
hydraulic single disc clutch
clutch pedal free play decreases
Simply put. when you depress the clutch pedal, it separates the clutch disc from the flywheel, when you let go of your clutch pedal it drops the clutch disc back onto the flywheel. Flywheel- spins at the speed of your engine (RPM) revs per minute depressed clutch-is seperated from flywheel allows you to shift into higher or lower gear released clutch- is engaged onto flywheel the two connect.. engaged clutch means your gonna move! disengaged clutch means you aint moving forward, your literally in neutral.
Clutch disc is worn out. Not knowing what vehicle you have, most are hydraulically operated and there is no adjustment. Time for clutch replacement.

Between the two clutch facings
Most likely, the clutch or the clutch pilot bearing is dragging. This is caused by clutch hydraulic leaks not letting the clutch fully disengage or the clutch pressure plate/disc/flywheel is warped. Crawl under the car, (engine off)have a friend push/release pedal, see if slave cylinder throw seems adequate and look for leaks. If throw is short, problem is in the clutch hydraulics; if throw is normal, problem is the clutch.
