How can I wash oil/grease out of my leather gloves?
I was going to ask a similar question about leather winter gloves with fleece lining a few days ago, but more along the lines of natural hand oils and accumulated germs picked-up before the gloves are put on. The first time I washed my bike gloves, in the sink with soap, tons of the black dye came-out. They were still black afterward, but a lighter shade. They are kind of cheap though, but still, maybe as suggested above some Simple Green or maybe a citrus-based product sprayed inside then a quick rinse with water will minimize the dye removal.
