Non-Disassembly Cleaning Methods
Vacuuming:Use a high-power vacuum cleaner (suction ≥ 2000Pa) equipped with a flat, slender nozzle. Position it close to the glass edge gap and insert it at a 45-degree angle to extract loose dust; this method is suitable for recently accumulated dust.
Compressed Air Purging: Use a professional air pump set to a pressure of 0.4–0.6 MPa. Direct the airflow through a nozzle with a 0.3mm aperture into the gap, using an anti-static brush to enhance efficiency. Wear safety goggles during the process to protect against rebounding dust.
Ionized Air/Static Removal: Use an ionizing air gun to generate a stream of positive and negative ions that neutralize static electricity within the interlayer, allowing adhered micron-sized dust to detach naturally. Follow up by wiping with an anti-static cloth in the direction of the electric field; this method is particularly suitable for museum display case glass that cannot be disassembled.
Chemically Assisted Cleaning: For stubborn stains, inject a neutral glass cleaner or diluted alcohol into the gap using a syringe. Allow the solution to sit and break down the stains, then use a vacuum cleaner on a low setting to remove liquid residue. Ensure no chemical residue remains to prevent water spots.
Disassembly Cleaning Methods
Small, Removable Glass Panels:Separate the layers of small laminated glass units (such as those in doors or windows). Wipe the inner surfaces in a single direction using a microfiber cloth and glass cleaner. Ensure the PVB interlayer film is completely dry before re-bonding the layers to prevent air bubbles.
Severe Contamination: If seals have aged, there is extensive dust accumulation, or foggy patches have appeared, it is recommended to contact professionals for disassembly and cleaning. Simultaneously check if the sealing strips need replacement. Self-disassembly of tempered glass carries a risk of spontaneous breakage; it is not recommended unless absolutely necessary.
