LEW STANDARD ROUND KNOBS BLACK
Because Winn grips have absorbent properties, they may eventually soil from dirt and perspiration from your hands. This does not affect the performance of the grip.
To clean a Winn grip, apply a small amount of water or rubbing alcohol to a soft towel, and gently rub the grips. Do not saturate the towel. Never use a brush and soapy water to clean a Winn grip because it may damage the top surface and destroy the tackiness and slip-resistance of the grip.
