Anyone have a magic recipe for cleaning white saddles? I never had any problem keeping older saddles on the whole fairly white-looking (I suspect that my old Regals were real leather or a heartier kind of Lorica or whatever is used) but the newer San Marcos use "Microtex" and tend to end up a funky greyish. Granted, this may actually be the break down of the dye from sweat, friction and (very likely) chamois cream. I recall a photo of one of Savoldelli's Regals and it had the same blue/grey sh*tty look so at least I'm in good company... Any suggestions on cleaning/protecting of said saddles would be appreciated. Thanks.
