Anyone have any good ideas/experience for processing a Tyvek envelope? Specifically a FedEx mailer, mostly white, made out of a Tyvek type material. Mag powder is all I can come up with and can't find any info in my files.

Thanks, wonderful CLPEX peeps!!

Mag powder was the first thing that came to my mind as well. Tyvek is designed to repel liquids so other than mag powder I would try CA fuming and a suitable stain of your choice.
