Now folks carry a container of fullers earth mixed with liquid detergent and glycerin. It removes oils and dulls the surface sheen from tippets. Makes them sink faster and less visible. This is a staple of English fly fishers who often fish still water lochs for trout. Now so well known in the states.

I wrote about using bentonite clay cat litter for fullers earth (bentonite) in the post below.
