I think there are so many ways to clean a firearm that as long as they are cleaned, and cleaned good, no one should have any troubles. I've flushed my cap locks out through the Nipple for years with a plastic tube over the Nipple to direct the cleaning solution away from the stock, regardless if they are pinned or wedged. With my flintlocks I've plugged the vent and poured my cleaning solution down the bore and let it set for awhile, poured the solution back out the bore, turned the flintlock sideways, soaked some cleaning patches, pulled the toothpick and went to swabbing. I've taken my locks out and scrubbed them with a tooth brush. Wipe everything down when it's all good and dry, given everything a very lite coat of sheath oil, and to this day I can go down to any of my rifles / firearms, run a white patch in and out the bore, and they still come out white - even if I haven't shot some of those rifles for years.
Cleaning a firearm (any firearm) is not rocket science. Clean it, and clean it good the first time after a shooting session and you're good to go for the next outing.
Toothbrush, Q-Tips, Cotton Balls, Paper Towels, Bore Brushes, Cleaning Patches and Jags, are great aids in your cleaning process, not to forget to mention a small portable air compressor. And never oil any part until you're sure there is no moister trapped anywhere within that firearm.
