Dissasemble the gun as the manual shows. I dont think you need to use solvent before you go to the range, I would take a old t-shirt and wipe all the surfaces dry, then run a drop of oil down each slide rail, put a drop of oil on your finger and wipe it around the outside of the barrel, and I usually put a drop on the inside top of the slide, where the barrel rubs against the slide when the slide is racked. once you put some rounds thru it at the range, you'll need to clean the entire gun with a good solvent, and relube with a THIN coat of gun oil over the entire gun. I like break-free CLP for mine.
