If you asked our 1200 members how then cleaned their guns, you would get 1200 different answers. The only way you can hurt your mini by cleaning it (I'm shure I will get some rebutal on this) is cleaning from the bore end without a bore guide. What you do is gradually wear out the crown, by the grit, and dirt on the cleaning rod rubbing against the crown. The other damage is the slovent if allowed to get into your stock, will soften your bedding.
Here is the way I clean my guns. I use a plastic coated cable rod, and clean from the chamber end, I run a patch wet with Hoppe's #9 Copper solvent, let it set for a couple of hours. Then I run another wet patch, then 4 dry patches, repeat till dry patch is clean. Sometimes I run a brush thru to speed cleaning stuburn stains. The blue color is copper, you have to clean all the copper out of the bore. After it is clean, and dry I run a patch thru the bore with Rem oil, then a dry patch. Before I shoot I run another dry patch thru.
I pull my stock off, to clean the bolt, Chamber, trigger group, and action about once a month. Once a year I take the gas block appart, to clean. The outside I just wipe down with Rem oil, and wipe off.
