I go about it the way most on here suggest. It is a bit different approach on this firearm compared to the bolt actions I am much more used to. I am able to properly clean the 15-22 with a few things most will have around the house.
1. Good supply of "Q-Tips". Probably the most handy and heavily used item for cleaning my semi auto pistols and now this new to me 15-22 (bought last month).
2. Tooth brush(s). I have been using these for years on firearms. Just save your old ones when they get worn and have family or friends do the same. I keep a few and label them for the cleaners or lubricants I use them with. For example I sharpie "Frog lube, Hoppes, CLP, etc" on them. That way I am using brush that only has that chemical on it to keep the cross contamination down. I also have one in an old "Kleen-Bore" kit that is cool. It has the conventional head on one side and a mini on the other. helps to get into tight spaces.
3. I bought a huge bag of firearm cleaning patches a few years back. It is still very full even though I have used hundreds. You can substitute old rags cut down to small sizes. But the patches are very inexpensive and you will use tons of them. If you buy a kit it will not come with too many so you will need extra anyway.
4. Bore snakes. I love these. I have them in .17 .22 9mm 44mag, 12 guage. Some of the sizes are cross usable. I can do all of my current firearms with those sizes. Very easy to use and do a decent job.
If you had only tooth brushes, Q-tips, patches (rags) and some bore snakes you would be able to handle even in depth cleanings. That is those things as well as whatever lubes and cleaning chemicals you decide on.
One other thing though not completely necessary is a rod and handle. The type that screws together to make a long rod with a t handle at the end. You can put all kinds of ends on it from patch holders to brushes. But the main key to it is being able to remove a round from the bore that has not made it all the way through. The one I have came in my old Kleen-Bore kit. I keep that kit in my range bag and though I do not use much of that kit lately, I like to always have it.
EDIT: Found a version of it online. Link:

Good luck which ever way you go. Happy shooting!
