Haven't seen any rainyet. California is like Florida in a lot of ways, but opposite too, lol. We get very little rain in southern ca, so the only thing I can attribute it to is sweat. I wear gloves when I lift weights, and it's the same stiff feeling that I get when my gloves needs to be washed, which means I'd usually just throw them in with a load of wash and they would come out nice and soft. I don't want to just throw my bike gloves into the washing machine!
I keep all of my leather care products at my dad's in his garage, so I'll have to see if I can't whip something up here. I may be able to find some woolite, or some other gentle cleansing solution. Thx for the help!
