check Kijiji and/or Facebook Marketplace for cleaning kits, always ones for cheap, with the Hoppes you pretty much got liquids covered, brake clean is good for gunk cleanup, some toothpicks and Qtips good for corners if any.
brushes, patches and jags (for pushing/pulling patches) will mostly come with any inexpensive kit. Not likely going to need any of LB303's suggestions until the addiction takes full hold
