Firstly check to see if your bat needs another coat of oil. To do this, using a reasonable amount of pressure, run your thumbnail up the blade of the bat, from the toe to just below where the front sticker is. If there is a tiny speck of oil where your thumbnail is, there is enough oil. However, if there is no oil the blade will need to be oiled again.

YOUR BAT SHOULD BE TESTED IN THIS MANNER APPROX. EVERY 3 TO 4 WEEKS.

Lightly sandpaper the surface of the bat with 180 - 200 grit sandpaper.
THIS SHOULD BE DONE PRIOR TO OILING YOUR BAT ON EVERY OCCASION.
Pour enough oil onto the blade of the bat to cover approx. a 50 cent coin.
Using either your finger or a piece of cloth, rub the oil into the front, sides and toe of the bat, ensuring none of the oil comes into contact with any of the stickers. DO NOT PUT ANY OIL ON THE SPLICE.
Leave the bat lying horizontal (blade up) overnight.
