How to clean the blackening of peach pits

The blackening of peach pits can be cleaned by physical cleaning, chemical cleaning, natural drying, deep treatment, and preventive measures. The main methods include soaking in warm water, wiping with white vinegar, sun exposure, cleaning with baking soda paste, and regular maintenance.

1. Soak in Warm Water

Soak the blackened peach pits in warm water for about half an hour, with the water temperature controlled at around 40 degrees Celsius. Warm water can soften the dirt and oxides attached to the surface of peach pits. After soaking, gently brushing with a soft bristled toothbrush can remove most of the black substances on the surface. For peach pits with deeper textures, soaking time can be extended or repeated multiple times. This method is not corrosive to the peach pits themselves and is suitable for handling slightly blackened peach pits.

2. Wipe with white vinegar

Mix white vinegar and salt into a paste, dip it in a soft cloth, and gently wipe the blackened surface of the peach pits. The acidic components in white vinegar can dissolve the oxides on the surface of peach pits, while salt plays a role in friction cleaning. After wiping, it is necessary to rinse thoroughly with clean water to avoid residual vinegar odor. This method is suitable for moderately blackened peach pits, but attention should be paid to controlling the force to avoid damaging the surface texture of the peach pits.

3. Sun Exposure

Place the peach pits in a sunny place for exposure, as ultraviolet radiation has a natural bleaching effect. Sunbathing for two to three hours a day, continuously for three to five days, can gradually fade the melanin on the surface of peach pits. This method is particularly suitable for treating peach pits that have turned black due to oxidation, but it is important to avoid prolonged exposure to sunlight that can cause the pits to crack. After exposure, walnut oil can be applied appropriately for maintenance.

4. Baking Soda Paste Cleaning

Mix baking soda powder with a small amount of water to form a paste, evenly apply it to the surface of the blackened peach pits, let it stand for fifteen minutes, and then gently brush with a soft bristled brush. Baking soda's weak alkalinity can neutralize acidic dirt on the surface of peach pits and has a good cleaning effect on stubborn black stains. After cleaning, it is necessary to thoroughly rinse with clean water to avoid residual baking soda. This method is effective, but it should not be used frequently to avoid affecting the texture of peach seeds.

5. Regular maintenance

To prevent the peach pits from turning black again, daily maintenance work should be done well. You can regularly use a soft cloth dipped in a small amount of olive oil or walnut oil to wipe the surface of peach pits, forming a protective layer. When storing, it should be avoided in a humid environment and preferably placed in a well ventilated and dry place. Before playing with peach pits, make sure your hands are clean to avoid sweat and dirt from adhering. Long term maintenance can effectively delay the rate of peach pit oxidation and blackening.

When dealing with peach pits, it is important to choose the appropriate method based on the degree of blackening to avoid using overly strong cleaning agents that can damage the pits. Keep your hands clean when playing with peach pits in daily life, and regularly wipe the surface with a soft cloth. The storage environment should be dry and ventilated, and a small amount of desiccant can be added to a sealed bag. For particularly precious peach pits, it is recommended to consult professional recreational maintenance personnel. Peach pits that are not played with for a long time can be lightly coated with natural oil and sealed for storage, which can prevent blackening and maintain glossiness.
