Coffee grounds unexpectedly have three unknown tricks to absorb moisture with delicious coffee grounds and exfoliating fertilizer.

After enjoying the delicious coffee, don't throw away the remaining residue, which is rich in antioxidants and alkaloids. Taiwan's "Chinese Health Network" summarizes several wonderful uses of coffee grounds.

Magic use 1: exfoliate. Coffee grounds is a good material for exfoliating. Rub it into the bath milk and massage the body to remove the aged cutin and make the skin smooth, compact, meticulous and shiny.

Ingenious use 2: moisture absorption and deodorization. Coffee grounds have many small pores, which can absorb moisture and remove flavor. Putting the dried coffee dregs in the cup in the refrigerator and microwave oven can remove the mixed smell of many kinds of food; it can replace the chemical aromatics in the toilet; it can also have a good deodorant effect in the wardrobe, shoe cabinet and car. It is best to replace it every two or three days to avoid mildew after absorbing water.

Magic use 3: natural fertilizers, pesticides. A study by Ohio State University in the United States found that coffee residue contains about 2% nitrogen, which can convert organic matter into fertilizer, which is a safe and environmentally friendly fertilizer. Huang Yu-Ming, an associate professor in the Department of soil and Environmental Sciences at Chung Hsing University in Taiwan, points out that whether the coffee grounds are dry or wet, they can provide nutrients for plants as long as they are laid on the top of the soil and let them decompose themselves, but it is not recommended to grow a large number of crops.

In addition, because coffee grounds contain alkaloids, they can be used as natural pesticides. First dry and grind the coffee grounds, then reboil the coffee with water, cool the coffee water and put it in a spray bottle, spray it on the place where there are insects on the plant, have the effect of deworming, and spray it once every two or three days.
