Daily cleaning is the foundation of landscape sculpture maintenance. Correct methods effectively maintain the sculpture's appearance, while incorrect methods can cause irreversible damage. Before cleaning, it's essential to determine the sculpture's material and then choose the appropriate method.
General cleaning steps are as follows: First, gently sweep away surface dust with a soft-bristled brush (such as a wool brush or nylon brush) to prevent dust accumulation and the formation of stubborn stains. For attached stains, such as mud or bird droppings, gently wipe with a soft cloth (or sponge) dampened with warm water, using moderate pressure to avoid friction damage to the surface.
Strictly adhere to cleaning precautions: Do not use strong acid or alkaline cleaners (such as toilet cleaner or bleach). These cleaners will corrode the stone's surface gloss, oxidize metal materials, and damage wood fibers. Use neutral cleaners (such as neutral laundry detergent or a special stone cleaner), and test on an inconspicuous area of the sculpture first to confirm there is no damage before use.
Do not use abrasive tools such as steel wool or hard-bristled brushes, especially on softer materials like marble and fiberglass, as these can easily cause scratches. While metal sculptures are harder, steel wool can damage the surface plating or oxide layer, accelerating corrosion. Do not use high-pressure water guns to directly wash the sculpture. High-pressure water may wash away painted or gilded layers, or cause water to seep into the stone crevices, loosening the structure. If washing is necessary, the water pressure should be low, and the water flow should be at a 45-degree angle to the sculpture surface, avoiding direct sunlight.
For areas with intricate carvings or openwork patterns, use cotton swabs dipped in cleaning agent to carefully clean them, avoiding residue. Cleaning frequency depends on the environment. Parks and squares, and other densely populated areas, should be cleaned 1-2 times per week. Suburbs and scenic areas, and other areas with better environments, should be cleaned every two weeks. After cleaning, promptly dry the surface to ensure the sculpture is dry and clean.
