The biggest weakness of bamboo is that it is easy to mold, crack and attract insects, and it can't be preserved for a long time in the natural environment. There are few bamboo furniture handed down from generation to generation before the Ming Dynasty. Modern bamboo products manufacturers have made special research on insect and mildew prevention of bamboo products. Some of these methods are simple, safe and nontoxic. Here are a few examples.

Insect repellent: zinc sulfate insect repellent. 9.5 kg of 0.5% hydrochloric acid, 0.5 kg of zinc sulfate and resorcinol 10 were taken into solution, and bamboo was soaked in it for 2 minutes and then taken out to dry.

Anti-mildew: Alum anti-mildew solution, take a small amount of alum and put it into clear water to make a saturated solution. Soak the bamboo ware for 2 minutes and then take it out to dry.

Demoulding: demoulding solution, which is prepared into solution A with 5g of sodium peroxide and 95mg of water; Mix 2% hydrochloric acid as solution B. Immerse the moldy bamboo wares in nail polish solution for about 1- 10 minutes, as the case may be, or brush off the moldy spots with nail polish solution. Rinse with clear water, and then soak in solution B. If mildew spots do not appear in 15 minutes, rinse with clear water and dry. "Bamboo Book Tibetan Law" records: "The products made by predecessors so far are very few, and those who get them must be covered with wood. Every two or three years, raw tung oil will be carefully brushed, that is, dried with cotton cloth to make it moist and not withered. If the wind is getting drier and stronger, don't go out to play to prevent damage and cracking. Its red is like amber, the color of goose oil is also precious, and black is the bottom. " It can be seen that maintaining bamboo carvings is also learned. Bamboo carving crafts are most afraid of sun exposure and should be stored in a cool, clean and humid environment. If you don't have time to play, be sure to put it away with a cloth cover or box to avoid dust and mildew. The color of bamboo carving is naturally formed by air oxidation and human hand rubbing. This is also part of the natural charm of bamboo carving crafts. It is not advisable to smear with color or strengthen oxidation with chemicals. Only by playing with your hands often and rubbing with your hands can you make bamboo look better. Some people want to polish bamboo utensils by painting or painting, which is not good either. Because the paint will soak into the notch. Oil pollution will damage the work. Others want to make the decorative patterns on bamboo utensils clearer and fill the notches with colors, but this "tacky" approach will reduce the artistic taste of bamboo carving, which is really superfluous.
