Use a good quality bore cleaner for the breech face and barrel, and a cleaner/lubricant to clean the rest of the gun. I use Breakfree CLP to clean and lubricate. Remove the slide and then the recoil springs, guide rod and barrel from the slide, there is no other disassembly needed. The following manual has disassembly and cleaning instructions for your gun. Always remove the magazine and make sure the chamber is empty before starting.
Cleaning and disassembly starts on page 34.
I hope this helps you,
