It is always good practice to check your oars and boat thoroughly before you hit the water. Any imperfections may result in changes in performance.  
 

Always wash or rinse oars after use. Dirt, sand and grime can wear the sleeves. If dirt and sand are on sleeve, increased wear will result.  If possible keep sleeves off the ground to prevent dirt and sand. 
 

VERY IMPORTANT -  When possible store oars out of direct sunlight and harsh weather conditions. Even at regattas try and keep your oars in the shade.
 

Remove handles twice a year and clean
