Gewehr 98

I picked up a Spandau Gewehr 98 made in 1917. The bore looks very good, but the exterior seems a tad tarnished. This is not my first milsurp ( in order M39, M1903A2, Long ranch No.4 MkIII*, M1 Garand), but this is likely going to be my first rifle that probably needs a proper cleaning as all of my other rifles were in much better condition and only needed a rub down with CLP.

So I'm looking for any information on what to do and what not to do when cleaning/mildly restoring this rifle. I was thinking I could just disassemble the rifle and give the barrel a good scrub with CLP paste or Hopps No.9 with brass tooth brushes

Also any additional info about this rifle in particular would be neat. The only thing I know about it was that it was made in Spandau Germany in 1917

Cheers!
