There are several schools of thought about what lube to use on o-rings, whether you should lube the outside of the liners, etc.
I only lube the o-rings, never lube the liners. I have no problems with the liners coming out of the cases. Attached are a couple of photos of how the internals came out of the cases for me today. Both are Hobbyline, one a 24/40 F12J and the other a 29/40-120 G64W. I've also had a 54/1706 K695R come out the same way, along with a number of other 29mm & 38mm HPR Aerotech loads.
The nozzle, liner, ejection charge, all come out of the case as a single piece. There is more to clean off the outside of the forward closure/ejection well, then from the inside of the casing.
