The following are the issues that need to be noted during the deep cleaning process of the Five Lotus Fireworks Burning Plate:
1. We need to conduct experiments first. The "symptoms" of Wulian Flower Fire Burning Plate vary greatly, for example, the formation of water spots can be caused by various easily deliquescent salts. Therefore, without understanding the specific cause of the stain, we suggest conducting a small experiment first.
2. Careful selection of cleaning agents is necessary. Some inferior cleaning agents are equivalent to strong acids, which may cause more serious damage to the surface of the lotus flower fire burned board after use, such as surface water spots and salt alkali spots, loss of luster and powdering, loose dissolution and yellowing, etc. Therefore, it is recommended that users choose high-quality products from good manufacturers. Secondly, the parts that are not to be cleaned should be protected before cleaning, and residual chemicals should be removed after cleaning. In addition, relevant experts should be invited to demonstrate the cleaning of stone cultural relics.
Generally speaking, the deep cleaning of the Five Lotus Fireworks Burning Plate should include at least the following three steps:
1. The cleaning agent enters the capillary pores of the five lotus flower fire burning plate through the infiltration process;
2. The cleaning agent in the fine pores of the Wulian flower fire burning board interacts physically or chemically with dirt molecules;
3. Remove the residue after the action by steps such as suction or dilution.
The basic operations for completing deep cleaning are the beginning and end steps, and the cleaning agent that can interact with dirt molecules in the middle step needs to be selected according to the material of the five lotus flower fire burning board, the nature of the dirt, and the convenience of the treatment process. This requires careful design and experimentation, so chemical methods have a unique effect here.

At present, we can use different types of cleaning agents to remove lesions such as salt stains and white spots, rust stains, organic spots, some water stains, and water spots. New cleaning agents are also being continuously improved and developed. In addition to common chemical cleaning methods, we are also experimenting with safer physical cleaning methods such as ultrasonic, laser, electrochemical, or particle flow cleaning.
