If you have noticed dark spots creeping in around the edge of your mirror, you are dealing with a common issue called desilvering. It happens when moisture or cleaners seep behind the mirror and break down the silver backing.

Common Causes

• Excess moisture from bathroom humidity
• Harsh cleaners sprayed directly on the mirror
• Old age and natural wear over time

How to Prevent Black Edges

• Always spray cleaner onto a cloth instead of directly on the glass
• Keep ventilation strong in bathrooms to reduce humidity
• Use a frame to cover and protect vulnerable edges

Fixing an Existing Problem

Once desilvering starts, it cannot be reversed. The best option is to cover the edges with a frame or replace the mirror if the damage is widespread.

Protecting your mirror from moisture and harsh chemicals will extend its life and keep the reflection clear for years to come.
