I wore the very light honey beige Ecco’s for a couple of days dusty and dirty gardening. Wiping them down didn’t get them as clean as I wanted, so I threw them in the wash with a load of towels. It was a big load so selected ‘warm’ normal cotton wash heavy cycle. I let them dry in the sun afterwards and they look brand new. The water did not darken the leather nor weaken any of the structure. Except for expected wear marks on the bottom, they look like they just came out of the box!
