How much do I need to worry about cleaning?

[emerson opdyck]

I’m a visitor from the northern parts of these forums, so don’t hold it against me if I’m asking a dumb or redundant question but...
I bought a refurbished Daisy m853 at Perry this summer and am having a ball shooting 10m in my basement. But it dawned on me I’ll that I’ll probably need to clean the barrel at some point due to the lead pellets. I’ve searched online and have found felt pellets, patches wrapped around tennis racket strings, nylon brushes. What do you guys do?
Thanks
