I was worried about that going in to it, but I think a lot of people decide that they are going to try backpacking, go out and buy all "the best" equipment out there, and then never use it. 10 years later, they realize they never really got into the activity and sell their stuff for cheap. The McNett down wash that WM recommends is super effective and has even removed bacon grease stains from my bags, which is something I've never been able to get out of my nice dress shirts I use for work haha.
There's got to be a term for that-like the average yuppie that drops $1000 at the Berkeley REI because their friend invited them to go camping in Tahoe for the weekend, and they never use the stuff again. You see them a lot here during the summer in the Eastern Sierras. They're always from the Bay Area and have brand new expensive hiking shoes. They'll tell you that "all the modern backpackers are wearing lightweight shoes" when you see them on the way in...and they'll end up using the Leukotape that's been around your lighter for a year that you never use.
