(1) Surface damage. Alkali or fluorine-containing substances sometimes released from concrete or building masonry during a storm may stain or corrode glass. The concrete structure in front of the window arch should be designed so that dripping water does not drip on the glass. When manufacturing prefabricated panels and other concrete wall materials, they should be fully agitated to make them uniform hydrates and fully cured. The surface treatment of the concrete (acidizing sandblasting, stone drilling, grouting, waterproofing materials, etc.) Finish before installing the glass, and the debris should be removed.

(2) Wash with solvent. Be careful not to use too strong solvents. Use solvents such as xylene, toluene, inorganic alcohol, or ether to remove grease and glazing materials, and then rinse and rinse, so as not to damage the sealant that fixes the glass.

(3) Normal cleaning and leaching. The glass should be cleaned, rinsed and dried frequently. Because fingerprints, oil stains, stains, dust, dross, sealant residue, scratches, and any surface abrasion are more visible on coated glass than on ordinary glass, we are managing and cleaning the coating Use extreme caution when working with glass. Use a soft, clean, dust-free cloth and a mild soap, lotion, or slightly acidic cleaning solvent. Immediately after washing, rinse with water, and then wipe off the remaining water with a clean rubber broom. Therefore, the coated glass may require frequent cleaning during the entire project, and a spacer plate should always be used between the coated glass windows.
