Instructions
Remove the larger pills by hand. Carefully pull away large balls of fluff. If necessary, you can cut some of these away if they resist being pulled, but be careful not to fully sever any yarn strings in the weave of the knit. Otherwise, your whole sweater could unravel.
Try getting rid of fuzz and pills with a strong adhesive tape, such as duct tape. This is a good method for removing the thickest and worst parts of the fuzz, rather than the finer layer.
Shave the fuzz away using a disposable, single-blade razor (it's easier to accidentally damage the sweater with two- or three-blade razors). Stretch out the sweater (or try this while you're wearing it) and run the razor over the fabric until it's de-fuzzed. Stop occasionally to clean the fuzz off the razor (use a downward wipe, not a sideways one, to prevent injury).
Buy a fuzz shaver made especially for this purpose. These devices can be purchased in big-box stores (such as Target or Wal-Mart) and may be sold labeled as "fabric shavers," "fuzz shavers" or "pill removers."
Get a sweater stone. This is a brick of pumice (rough, pourous stone) that's sold for the purpose of removing fuzz with gentle abrasion.
How to De-fuzz a Sweater
Most of the time, sweaters are the ideal age-defying garment. A good sweater can keep you warm and cozy years after other clothes have fallen apart and worn down, but there is one way that sweaters commonly show their age: fuzz.. As the individual yarn strings fray slightly, these tiny threads form a layer of fluff around the garment, or worse--fluffy pills of compacted fuzz. Luckily, there are a few easy remedies and products you can use to make your old sweater look almost new.
