I have a pair of Nudie Flare Glenn (BCO Denim - ridiculously difficult to break in) that have over one year of wear (December 17, 2006). They have been used when installing suspension in a car, 6 oil changes, radiator replacement, turbo kit install, and have a ton of miles on them. I am pretty sure there is a lot of coolant, oil, gasoline, sweat, snow, rain, blood, and various food sauces on them (does calamansi accelerate the fading process?) I will be washing them in the next couple of months, any tips?
