I'll have to look around. The only lanolinolated wash I know of here is called Eucalan. It has Eucalyptus. Which I am screamingly allergic to. Hopefully there is an alternative, as I suspect your idea is the way to go.

BTW - do you know of any extant Tailor's books hanging around in Uni libraries in your vicinity? Like the Tailor's Book of Enns or Alcega's book?
