I think I'll probably have to wash my aristocrat pretty soon. Kind of nervous about ruining the waterproof effects. I found something in the laundry room called 'lano-rinse--a natural conditioner for wool'. It says it 'replenishes natural oils, restores life and softens the wool' plus it contains lanolin oil. And it's biodegradable. Anybody use this product? If not, whaddya think, could I go ahead and use it on the aristocrat?
