I have an old (well over 30 years old) Parker Hale stainless steel rod, a Dewey rod, lots of Hoppe's gun potion #9, and Rem Oil. I buy (when needed; generally a long time between purchases) white, 100% COTTON flannel material that I rip/cut as needed for any size patch I want for cleaning. I launder and dry that material once to get any sizing out of it, then use it as I need. I have enough properly sized brass/bronze brushes and brass jags to use for any of my firearms. I also like to use old toothbrushes for cleaning tight spots daubed with a little #9 if needed. After a bore is cleaned and dried, it gets a light coating of Rem Oil. This stuff and the usage of it for cleaning my guns has worked very well in the climate of Wyoming where I live. I also use a bore guide when I can clean from the breech. I have an old Outers plastic gun cleaning case I've had forever to hold all the stuff mentioned handy when I need to clean. All the extra stuff I have on hand is stashed in my reloading cabinet.
When I was a kid and was old enough to have my own firearms, my dad made sure my two older bros and me kept our guns clean. I was a lifelong habit taught, and caught, from my Old Man. Now, I'm one...and I like to think my boys will do the same to their guns...without having to be told.
Don't fudge on a rod, buy a good one and wipe it down between passes on a bore you're cleaning. If your 30-30's a Marlin, that a good thing; you can clean that one from the breech.
