I use a small make up brush for a pan brush...I do think you need one of these, not to clean after shooting but to clean when you don't shoot so you leave no powder in the pan...I use one when I'm going to pull my flinter up in the stand or when I didn't get a shot and I'm leaving her charged...It only takes a couple of grains to ignite a flintlock so don't drop the hammer on the frizzen with a charge in the barrel...
You also need a cover to put over the frizzen...They are made of leather and I have a leather thong attached to mine so I can slip it over the frizzen and the other end is tied to my trigger guard...
Make a touch hole pick...Take a small finishing nail and a deer antler tip...Drill a small hole into the tip and epoxy the nail into the end and you have a touch hole pick...
I use a larger finishing nail to knap the frizzen...You can use your short starter as a hammer to knap...
