由于銅雕塑會(huì)與空氣里的二氧化碳和水參加反應(yīng)生成堿試碳酸銅也就是銅銹,為了使銅制品防銹,就應(yīng)該定時(shí)放入吸水劑并存放在干涼的地方。不可接觸的除了酸性物質(zhì)之外,還有鹽水等一類的雜質(zhì),都會(huì)腐蝕銅表面,還會(huì)長出銅綠等一些復(fù)合生成物.還有銅受高溫后暴露空氣中會(huì)變?yōu)?應(yīng)注意保護(hù).另外,銅佛像除了保護(hù)銅制品本身以外還應(yīng)該注意尊敬.佛像應(yīng)放在凈處,最好單獨(dú)收拾出一塊空地.佛像上可蓋一層凈布,這樣不會(huì)褻瀆,防止落灰塵,可以保持佛像潔凈。假如銅像上的銹比較輕，可以把白醋兌水后，放入浸泡，然后取出，用小刷子刷去殘銹，再用清水洗凈醋液，用軟布擦干即可。如果銹比較重，就要用醋酸、鹽酸除銹，但是醋酸、鹽酸的濃度不好掌握，沒有經(jīng)驗(yàn)的人不可貿(mào)然使用。不管是用什么方法除銹，也不管是除何種銅器上的銹，都要先在小面積上試一試，以免方法不當(dāng)出問題。
Because copper sculptures react with carbon dioxide and water in the air to form alkaline copper carbonate, or copper rust, water absorbents should be placed regularly and stored in a cool, dry place in order to prevent rust. In addition to acidic substances, there are also impurities such as brine, which will corrode the surface of copper and produce some complex products such as copper green. Copper will turn black when exposed to high temperatures and should be protected. In addition, the statue of the bronze Buddha should be respected in addition to the protection of the copper itself. Clean up a piece of open space separately. The Buddha statue can be covered with a clean cloth so as not to blaspheme, prevent falling dust, and keep it clean. If the rust on the bronze statue is relatively light, you can mix the white vinegar with water, put it in the soak, then take out, brush away the residual rust with a small brush, then wash the vinegar with clean water, wipe it with a soft cloth. If the rust is relatively heavy, it is necessary to use acetic acid, hydrochloric acid rust removal, but the concentration of acetic acid, hydrochloric acid is not easy to grasp, inexperienced people can not use rashly. No matter what method is used to remove rust, and no matter what kind of copper rust, we should first try on a small area, so as to avoid improper method of problem.
