The lanolin treatments I've seen have been wash-in. I have some Filson wool pants and coats that say dry clean only, no washing. Are there any spray-on lanolin treatments available that would allow me to get around washing in the lanolin?
I've had a Filson cruiser for ~8yrs. It sees nearly daily use in WI winters & gets washed every spring. I use gentle cycle, cold water, woolite and hang dry. It looks fine. I think this lanolin treatment will be included this spring before I hang it up to dry.
