Tea has an adsorptive effect on gases. Generally, tender tea has stronger adsorption capacity than older tea, and green tea is better than oolong tea, black tea, and dark tea; baked green tea is better than pan-fried green tea; tea with a larger surface area is better than tea with a smaller surface area. The scenting of various scented teas takes advantage of tea's adsorptive properties.

Refrigerator deodorization: Wrap leftover tea leaves in gauze and place them in the refrigerator. Every half month, take out the tea bag and sun-dry it in the sun, or dry it on a radiator in winter. Then put it back in the refrigerator for repeated use. Orange peel can also be used.

Bad breath: Tea has antibacterial and antiseptic effects, and its own fresh scent is effective in eliminating bad breath. Green tea is cool in nature and can help with bad breath caused by internal heat. In daily life, drinking tea or chewing tea leaves can help maintain a fresh and healthy mouth.

Foot odor: Add leftover tea water or unused old tea (reusing it) to hot water for soaking feet. Soak for a while to eliminate odor, and it can also kill bacteria and help prevent athlete's foot.

Musty smell in closets and drawers: Put dried tea leaves into gauze bags and place them in various spots. This not only removes the musty smell but also releases a fresh scent.

Cleaning smelly utensils.

Soak leftover or old tea in water together with the utensils for a while. After washing, the odor will be removed as well.
