How should the gold plated contact points on the goggles and helmet be cleaned?

The most effective method for cleaning the gold plated contact points on goggles and helmets is using an eraser. Gold plating is sensitive and can be damaged by harsh chemicals or abrasive materials. An eraser is a gentle tool that can effectively remove dirt or oxidation without scratching or harming the delicate surface of the gold plating.

Using an eraser helps to ensure that the contact points maintain their conductivity for proper performance of the night vision goggles. Other methods, such as using a damp cloth, alcohol wipes, or a soft brush, may not provide the same level of thorough cleaning and could potentially leave residues or cause damage.

In practical maintenance of night vision equipment, it’s crucial to use methods that preserve the integrity of the electrical contacts while ensuring a good connection for optimal performance.
