Acquired some Grangers and Nikwax - getting ready to wash my j1a-gt for the first time. going to follow these procedures (plus remove jacket sling & loosen draw cords on hem and hood) :
Any other sage advice? Should items be washed separately? What fabrics can be machine vs hand washed. Dryer vs. hang dry? Grangers for everything? Nikwax on only GT? Best practices to reduce the amount of fading?
EDIT: thanks @CARLOOA for the following:
How do I wash this stuff?
As a general best practice with performance technical fabrics:
1. Run the clean cycle on your empty washer.
2. Double rinse your washer if it’s old. Fabric softener and harsher chemicals can negatively affect material performance.
3. Use technical fabric wash if possible, otherwise use a water based detergent.
4. Zip up jacket and turn inside out to prevent buttons getting fucked and run not on hot.
5. Double rinse.
6. Hang dry.
7a. If you’re experiencing wetting out (when the water doesn’t bead), you may need to reactivate or redistribute DWR, keep inside out and tumble dry low heat or iron on low.
7b. If you’re experiencing wetting out still, you may need to reapply the DWR. if using spray, remove from washer, apply liberally, tumble dry if needed (some sprays don’t require heat to reactivate). If you used 2 in 1, tumble dry if needed.
What I do—YMMV:
Sell before you wash it, duh. Just kidding:
For jackets: single wash cold, double rinse.
For S/CH: single wash gentle cycle, no spin—don’t really want premature abrasion though generally these fabrics are pretty hardy. Manufacturer says proprietary coatings. DWR reapplication should be fine. I use a steamer to get the wrinkles out after air drying.
For DS: single wash cold, double rinse. Manufacturer says proprietary coatings. DWR reapplication should be fine.
For GT/WS/S: Everything is DWR'd, this is a coating on the face fabric that allows the water to bead out. With abrasion this comes off, to reactivate wash, reapply, and depending on what DWR, tumble dry or iron. I use Grangers.
For PB: since no outer fabric and no DWR is used no tumble drying or DWR is needed.
