This is barely worth the effort but..
Sharpie, do you know what I offer under a "cleaning clinic"? Doubtful.
You are obviously an expert on gun cleaning and have your own methods which is fine just as others do. However there are plenty of shooters who don't and wish to know more, some ask a question on a forum such as this and get a myriad of largely innacurate suggestions.
For some time I have been using Wipeout products, I run a commercial range and need to keep several rifles properly clean every week and thus far have yet to find any other product that works as effectively and quickly as wipeout. One of the most common questions I get asked is how to clean a rifle which is the reason I offer the service I do which is an extension of a normal range session where a shooter can zero their rifle, clean it thoroughly and then re-check zero after cleaning to give them the confidence they need to keep a rifle clean, they also get a discount off some wipeout if they decide it is for them - how many shops offer this but still take your money - the difference is I can prove it works and stand by it.
I do not sell rods, jags, patches etc because there are plenty out there which fit the bill, but I do supply wipeout as do others because it works, I even produced some simple videos to show how to use it easily and prove it worked.
I have never commented on bore snakes but do use one to remove powder fouling from the bore if I've only fired a round or two.
Why people not clean rifles is beyond me, sadly the two most common reasons (and this will stir things up) is laziness and not knowing how to. To all those who never clean and can still head shoot a fox at 400 yards, do you put a shotgun away dirty?
The fact is, rifles can lose accuracy if a build up of carbon and copper is allowed, these two will not 'damage' a barrel but the powder fouling residue will - take a deep sniff in your moderator after a few rounds, ammonia, one of the products of combustion of a nitro based powder, combined with oxygen produces moisture and eventually you get Nitric acid, the stuff in your car battery - you want that **** near your barrel?
I don't give a fig what products people wish to use (mostly driven by what the local shop sells) but I do advocate using at least something, I use what I do and I stand by that product 100% as do many other people coincidentally. As for the 'profit' side of it, that's been done to death times many on this forum in various forms from the cost of stalking to cleaning fluids and quite frankly it's just boring now - sadly rifle shooters are some of the tightest around, everything should be free and the world owes them a favour - change the record.
Blaser 6.5 will have a session with me where he can zero his rifle, clean it properly and shoot it again to make sure it's point of impact hasn't changed - if he wants to buy a bottle of fluid afterwards that's up to him - at least he'll know how to clean the barrel of his expensive rifle properly.
But as they say YMMV!
