Frequently asked questions

Reflection mirrors are usually made of materials such as B270 and float glass. B270 is a high-quality optical glass known for its transparency and high light transmittance. It is very durable and is often used in precision optics because of its minimal chromatic aberration.

Float glass is a standard glass made through a process that ensures a uniform thickness and a very flat surface.
Both materials are very durable in general use. However, their lifespan may be affected by factors such as usage environment, maintenance, and the quality of the reflective coating. Regular glass care and proper handling can significantly extend its lifespan.

Gentle Cleaning: Use a soft, clean cotton wipe to avoid scratching the surface. A microfiber cloth is ideal.

Proper Cleaning Solution: Use a cleaning solution specifically designed for optical surfaces or a mild dilute soap solution. Avoid using harsh chemicals that can damage the mirror's coating.

Avoid scratches: Gently wipe the mirror in a circular motion, starting from the center and moving outward. Avoid applying excessive pressure.

Dusting: Before wet cleaning, use a gentle hair dryer or soft brush to remove dust and loose dirt to prevent scratching.

Handling Care: Always hold mirrors by their edges to avoid fingerprints and smudges on the reflective surface.

Environmental protection: Store and use the reflective mirror in a clean, dry environment to prevent moisture or dust accumulation.

Regular Inspections: Regularly inspect the front surface mirror for any signs of wear or damage, such as scratches or deterioration of the reflective coating.
