I have been wearing these for years now. Love them. Others are bulky or stiff. These you can pick up a dime while wearing them. I buy a couple of pair a year but the old ones only seem to wear out on one hand! $ 6 or 7 each.
As for washing? I keep them on my hands and scrub. Then set them in a mild mixture of bleach and water. Heavily rinse and dry outside in the breeze.
