If you recently bought a cashmere or merino sweater, then you most likely found a "dry clean only" tag sewn into the seam. Before taking it (and your wallet) to the cleaners, give hand washing a spin.
Fill your wash basin or sink with tepid water and the recommended amount of detergent. Submerge your garment and gently squish the water through; let soak for 10 minutes. Here comes the fun part -- if you're using a no-rise formula, there's no need to rinse! Simply drain the water and gently squeeze any excess moisture from the garment -- never wring it or you risk stretching your garment out of shape.
Place the wet garment on a clean white towel and roll them together, gently squeezing as you go. To remove even more moisture, try one of our favorite hacks courtesy of the Yarn Harlot: place your roll on the floor and walk on it! Should you soak through the first towel, have a second one handy and repeat the process. The more moisture you remove, the faster your garment will dry.
Unroll your garment onto a dry, flat surface. "Block" or gently mould your garment back into shape; this is how it will dry. For faster drying times, pick an area of the house with ample air circulation but away from any direct sources of heat.
Once completely dry, finish your sweater spa treatment with a gentle "gleening." The Gleener Ultimate Fuzz Remover is like an exfoliator for your wardrobe; use it to remove pills and fuzz balls from your most treasured textiles -- even cashmere. Pay special attention to high friction areas like the bust, underarms, and sleeves.
Put it on and enjoy your freshly primped sweater/scarf/whatever or fold it and stack for later. Never hang woolens or you risk creating hanger bumps.
