Method 1: Soaking in Plain Water
Time: 1 hour
Amount: 1 bowl
One bowl of tap water. Put the fragrant pears and blackcurrants directly into the water and soak for one hour, then change the water and rinse once.
Result: The water quality showed basically no change, with only a small amount of impurities precipitated. The wax on the surface of the fragrant pears was slightly removed, and it no longer felt as greasy to the touch. The surface of the blackcurrants did not change much, and a small amount of fruit powder remained.
Method 2: Cleaning with Starch
Time: Half an hour
Amount: 2 spoonfuls
One bowl of water, add two spoonfuls of starch, mix well, and put in the fragrant pears and blackcurrants. Soak for about half an hour, then change the water and rinse once.
Result: The water quality did not change much (because starch was added, the water was already turbid), with a small amount of impurities on the water surface. The wax on the surface of the fragrant pears was basically washed off, and the surface of the pear showed its luster, feeling very clean to the touch. The white substance on the surface of the blackcurrants still remained.
Method 3: Scrubbing with Salt
Time: About 5 minutes
Amount: 4-5 spoonfuls
Sprinkle salt directly on the surface of the fragrant pears, then rub them repeatedly with your hands, and rinse with water once.
Result: This method uses the friction of salt particles on the fruit's surface to remove wax. The effect was quite good; the wax layer on the surface of the fragrant pears was basically removed, and it didn't feel greasy to the touch. However, washing just one pear used about four or five spoonfuls of salt, which felt a bit "too wasteful."
Method 4: Using Shell Powder
Time: Half an hour
Amount: 2-3 grams
The shell powder was an online purchase of a Japanese brand. The instructions stated that shell powder can not only wash fruits and vegetables but is also useful for washing clothes, pots, and pans. One bowl of water, add about 2-3 grams of shell powder, mix well, then put in the fragrant pears and blackcurrants. Soak for about 30 minutes, and finally rinse with clean water.
Result: After soaking for about 2 minutes, a layer of oil could be seen floating on the water surface. After about 20 minutes, the water surface was completely covered with a thin layer of wax, much like candle wax dripping into water. When touched, the white wax stuck to the fingertips. After rinsing with clean water, the wax on the surface of the fragrant pears was basically gone, and the natural luster was visible without feeling greasy; the white substance on the blackcurrants also basically had no residue, and rubbing the skin gave a very "crisp" feeling.
