Okie dokie. Called a buddy and he said while many never clean it (like moi) it is recommended. About every 6 months.
He also gave me a simple recipe for a dressing. I know you have a store bought conditioner but maybe someone else will come along and want to try it. I'm going to.
1 pound lard 4 oz ivory bar soap 1.5 cups water
Heat water and shave soap into it. Once soap is dissolved, cut in lard. Stir over gentle heat till a creamy paste is created. Pour off to a plastic tub and cool.
Said if you need a bit of waterproofing, cut "some" beeswax into it. He cooks like I do, apparently.
He says it’ll last for years.
I'm only 60 or so conditionings behind!
