The process I’ll use for handwashing Smartwool socks.
Based on her advice, I have decided to use the following process for the handwashing of my brown (adrenaline outdoor) and gray (adrenaline hiking) socks.
handwash and air dry. i’m a knitter and i suspect that smartwool is a combo of superwash wool (wool chemically treated to resist felting) and nylon (and lycra).
still, i wouldn’t trust the superwash thing– all wool will felt over time with constant agitation and definitely will shrink with machine drying (ask me how i know…a certain superwash wool scarf shrunk over time).
what i’ve done with woolens is to wait until they all get dirty, fill a bowl or sink with luke warm water and no rinse detergent like soak or eucalan (not woolite), put the woolens in, squeeze gently to let water flow through, and after 15 minutes, take them out and put them in washer using spin cycle only. then i put them flat on a towel, roll up towel, stamp on the towel to soak up any remaining moisture, and then lay them flat on another (dry) towel and let airdry.
a bit laborious but my handknits have survived pretty well and those that i’ve machine washed and dried look worse.
Thank you sleepyneko!
