Best way to wash kuiu synthetic dwr clothing?

[bojangles808]

With Tiburon pant top (dwr) do I wash with nik wax type dwr detergent or the scent free uv dead down wind type detergent that I use on my other camo? Hand wash or machine? Warm or cold? Really want to keep dwr intact

I use Penquin Sport Wash. Scent-free and isn't supposed to affect the DWR.
