For basic maintenance, clean your Zipp wheels with soap and water. If using a power washer when cleaning your wheels, ensure that you do not spray directly into the bearings. Avoid spraying degreasers directly into the bearings as well. For hub maintenance, see our service site for hub maintenance manuals. More maintenance information can be found in the maintenance section of your wheel owner's manual:
