A good paint remover will get that bubba goo off, get one that isn't good for the environment an has warnings all over the label. Use mineral spirits and rags to remove the leftover reside.
Now, you can either stain it with Chestnut Ridge as Sakorick suggested the stuff gives the aged look with a red hue,I love it. Or just start wiping the stock with BLOicon, it has dryers in it and looks just as good RLO. Which ever you chose wipe it on leave it for an hour or two and wipe off. Let dry 24hrs and repeat the stock will stop soaking in the oil when it's had enough. Don't keep going,your just wasting your time and you can put too much on which is a sticky mess. This is of course a short description and depending on the stock there are other things that can be done but it isn't rocket science if you tackle the job yourself. My 2c's

p.s
From start to finish should take about week to week 1/2...
