1, Brush: When brushing walnuts, brush from top to bottom along the texture and trend of walnuts. Brush in one direction for dozens of times, and then brush in the opposite direction for dozens of times, which can make it easier to clean the dust in the depths of walnuts. If you brush back and forth, it will actually affect the effect.

2、? Side brush: tilt the brush at an angle, and then brush along the direction of walnut grain, so that the dust adsorbed on the side of the grain wing can be easily brushed off.

3. Pick the brush: press the brush into the depth of the grain, and then rotate the brush head by hand, just like picking things with a needle, using the hardness of the bristles to pick out the dust accumulated in the depth of the grain.

4. Brush pressing: Gently press the brush into the grain of walnut, and feel that the bristles are slightly deformed. Maintain this strength and move the brush back and forth in a small range for brushing. This method can effectively remove dust and sludge from the grain pit which is not too deep.

5. Brush: This method is a quick way to remove stubborn stains. Put walnuts in the palm of your hand and hold a brush in the other hand at a certain distance? Pressing down from a height into the depression of the walnut grain can also increase the strength in the process of smashing.
