Always read the care label. When it comes to chosing a chemical to clean the garment - follow this advice below. It is mostly applicable to garments that have some level of water repellancy & breathability that you want to maintain.

Typical laundry detergents contain fabric softeners, fragrance and color brighteners which are water-attractive residues—not something you want on the surface of your outer shell (Detergent will not remove DWR but the residue will 'cover it' so it will not work as well). Most washing machines will rinse the product sufficiently and not leave this residue. You will have to work a bit harder if hand wahsing. 

So ideally use a dedicated product from Granger's range (Most outdoor retailers will stock a suitable product). A mild powered detergent, such as  “Dreft”  or soap flakes is also acceptable if thoroughly rinsed afterwards although it may not be able to get out stubborn stains

Do not use a liquid detergent. It leaves a residue, which clogs the pores of Gore-Tex and other laminate waterproofs and never use hot or cold water on Gore-Tex. Always use a warm wash and a warm rinse. It is extremely important to rinse the garment well for reasons already listed. We recommend two rinse cycles or wash it once with detergent and again without.

Dry in dryer on LOW heat, at the end of the drying cycle, you may increase the heat to WARM and dry for an additional 15 minutes. This will remove some of the wrinkles from the fabric. Remove at once; do not allow the garment to remain in the dryer (it may cause burns on the fabric if it sits on the hot metal).

You may use a spot cleaner to remove stubborn spots before washing. Granger’s G_Wash Spray Cleaner Plus works well.

If necessary, grease can be spot cleaned at the dry cleaners and then sprayed with any non-silicone spray - but do NOT dry clean the whole garment.
