Now it's easy: wash, dry, use, and enjoy! 
Wash:
If possible, use liquid detergent (to avoid residue)
No fabric softener – adding a little white vinegar can help soften harder fabrics
Low spin cycle
Low temperature
Dry:
Preferably out of direct sunlight
Hang in a zigzag pattern (except for wools)
Avoid tumble dryers (when possible)
Use and enjoy:
Without moderation
With lots of love
How to soften a wrap/ring sling:
Use as a seat in the car, on the sofa
Place under the sheets
Braid it
Steam it

Tips:
It should always be washed before use (no matter how tempting it is, so that the fibers adjust naturally and nothing gets damaged :p)
Ring Sling:
Wash inside a pillowcase to avoid scratching the rings or potentially damaging the machine or rubber parts
Carriers:
Avoid frequent washing due to the foam padding they may have. Hand washing can be a good option. To protect buckles and padding, use inside a pillowcase. Sometimes a damp cloth is enough to clean dirt.
