Re: new to fleece
Lanolin actually does help a tad on poly fleece. Some people increase their water-resistance by washing them with fabric softener, which coats the polyester with who knows what. Coating the fleece with lanolin increases its water resistance by coating it with something natural, that also breaks down urine.
I love using Eucalan on all sorts of non-wool items in our house, that are exposed to stuff like perspiration ... fleece, bras, silk, polyester shirts ...
