This is now the second time I cleaned my Guide's Pack.
The first time I used Dr. Bronners liquid soap,
Although it cleaned it well, I did notice a bit of a reduction in the sheen of the Parapack,
Especially when comparing it to other non-washed Parapack of the same color. (Olive)
Upon my second time, rummaging around the house I discovered my wife's
Delicate Fabric wash & Stain remover used for lingerie by Nordstrum.
Using a few capfuls in about 6 inches of water in the tub,
I'm happy to report that there is now a happy sheen.
