How to Oil a Cricket Bat Properly
How to apply linseed oil lightly to natural willow, what to avoid and when a fitted facing changes the process.

Use light coats only and let each one absorb before adding more. Avoid over-oiling, standing the bat in oil or putting oil beneath a fitted facing.
Why oil a willow bat?
Light oiling helps condition exposed natural willow and reduces the risk of the blade drying excessively before use.
How much oil?
Two or three light coats are generally enough for exposed natural willow. Let each coat absorb with the bat lying flat or slightly elevated before applying another.
Do not over-oil
Too much oil can soften the willow excessively and add unnecessary weight. Do not stand the bat in oil.
What if the bat has a facing?
If a facing is already fitted, do not oil underneath it. Oil can interfere with adhesive and may lift the facing.
Oiling is not knocking-in
Oiling conditions the willow. Knocking-in compresses the fibres against impact. A bat may need both depending on its finish and manufacturer instructions.
Practical rule
When in doubt, follow the preparation instructions supplied with the exact bat. Pre-prepared, faced and natural-finish bats can require different treatment.
