Use expired black tea

1, expired black tea can be used to eliminate odor. If the newly renovated house can help remove the smell of formaldehyde in the house, add 300 grams of black tea evenly into the bucket or washbasin and put it in the living room to open the window for ventilation. Generally, the formaldehyde content will drop by about 90% within 48 hours, which can obviously reduce the irritating smell.

2. Expired black tea can be used as a tea pillow or a deodorant for shoes. Tea pillows can effectively improve the quality of sleep. Dry the long-standing black tea and then make it into a tea pillow by hand. Smelling the fragrance of tea to sleep helps to relieve mental stress and make it easier to fall asleep. If there is foot odor, make dry black tea into a small purse and put it in your shoes to eliminate foot odor.

3. Expired black tea can be used to cook tea eggs, which can be dry tea or soaked black tea. Gently break the eggs cooked in advance and put them in tea, and continue to cook for a period of time. Soon, the tea eggs with rosy color and delicious taste are ready.

Expired black tea can burn to repel mosquitoes. It is always bitten by mosquitoes in summer and buzzing at night. If you use mosquito-repellent incense, you may wish to order dried black tea, which can effectively repel mosquitoes, and the effect is even better than mosquito-repellent incense.

4. Black tea can eliminate the puffiness of dark circles. Soaking black tea in eyes can relieve inflammation and redness, because tannic acid contained in black tea has astringent effect, but tannic acid is also irritating. It is best to choose soaked black tea, which can reduce the concentration of tannic acid and not irritate the delicate skin of eyes.
