No suprises to find that my preference is to dry clean, simply because I like to keep my jeans as mint as possible, although I agree normal washing does soften them up ( Ive got a wrecked pair of RMC's I wear regularly that just get a normal wash for example LOL). For me normal washing reduces the second hand value of the jeans, not that I plan to sell any of course, but certainly on the rare occasions I buy second hand I generally wont entertain jeans that have been heavy worn or washed a lot, although some collectors may prefer it the other way round.
