①? Dry brush method: just don't go into the water, so you must not clean it thoroughly in the water (dry brush again). Dry brush method, not with wild bristles, but with a steel brush, can completely clean the dirt on the peach pit with just brush. The disadvantage of this method is that a bad steel brush will blacken the peach core, and a heavy brush will scratch the peach core.
So this requires a skill and experience, but scratches are not very important, because long-term disk play will soon disappear (similar to the dry grinding of the stars and moons); Steel brush cleaning, you need to shake the peach pit, then clean it rhythmically and repeatedly, and finally clean the residue with a wild bristle brush, which is equivalent to polishing.
②? Water brush method: the key point is that warm water can reduce the problem of temperature difference (reduce the cracking coefficient). If you brush with water, there is definitely a possibility that the peach core will crack (in fact, the small cracks in the peach core will be covered by cement slurry). It is best not to soak the peach pit quickly with a hard brush with little water, and then dry it quickly with a towel. The most important thing is to dry in the shade.
Both methods are wrapped in towels or newspapers and dried in the shade.
There is another way: peach pit is very angry, so angry. Soak in water for at least half an hour before cleaning, and then clean it with hardwood brush. Some fine seams and eyes that can't be brushed are patted with a brush, and it will be clean if you look at it repeatedly. You can also use a boiling pot to cook for 30 minutes and then clean it, and the effect is also very good.
Extended data:
First, anti-cracking: cracking is a common phenomenon in nuclear carving. The principle of cracking is uneven humidity inside and outside the core. The air humidity in the nuclear and the humidity outside the nuclear should be balanced. If there is a big difference between the inner height and the outer height, the inner humidity will expand outward, and the nuclear surface will shrink inward when it is dry, resulting in cracks. Nuclear carving crafts cannot be exposed to the sun, soaked in water or blown by the wind for a long time.
Second, oiling: the nuts themselves have a lot of oiliness, but with the passage of time, the oiliness will dissipate, so be sure to oil them to strengthen their oiliness. If it is less oily, it will crack easily. If it is coated with oil and eaten inside, the whole nut can absorb oil. The method of oiling is: dip a soft brush in a little light-colored oil (olive oil, peanut oil, salad oil and soybean oil), first brush it on any appliance for a few times, so that the oil can flow evenly on the bristles, and then you can engrave the North Korean nuclear and fill it with oil.
Third, the anti-flower point when oiling or cleaning the nuclear carving, first drop a few drops of oil on the brown brush, and the amount of oil should be less. After brushing, brush it again with a brown brush that does not drip oil, and brush off the oil accumulated in the deep recess. Finally, suck it with a soft cotton cloth or paper towel and wipe off the accumulated oil. ?
