the first method:
The most effective and thorough way to remove the garlic flavor is to use sugar water. Pour white sugar into the cleaned fresh-keeping box. More white sugar will be effective. Pour in clean water. The ratio of sugar to water is preferably about 1:3. Cover with a lid, and place the lid on the bottom for one night. After rinsing it with clean water the next day, let it dry in the sun for 1 hour, and you will find that the peculiar smell has completely disappeared. In addition to garlic smell, fishy smell and other peculiar smells can be removed by this method. The effect of using white sugar is not to say, the disadvantage is that white sugar is a bit expensive and the cost is a bit high.
The second method:
It is much better to use a glass crisper, but unfortunately the lid is still plastic, which is still prone to peculiar smell. Although the effect is so much worse than white sugar, the still very useful method is to use flour. Pour flour into the basin, pour in clean water and stir well, soak the lid of the lunch box, soak for one day, rinse with clean water and let it dry in the sun for an hour or two. In addition, baking soda powder, coffee grounds, vinegar, etc. also have a certain effect, but they are not as good as sugar and flour.
