To maintain steel survey chains effectively, keeping them dry and clean is crucial. Moisture and dirt can lead to rust and corrosion, which compromise the accuracy and longevity of the chains. When steel survey chains are exposed to moisture, they are at risk for oxidation, leading to deterioration in performance. By keeping them clean, you ensure any debris that could cause wear is removed, and by keeping them dry, you prevent oxidation caused by moisture. This practice extends the life of the survey chains and helps maintain their precision during surveying tasks.

Other options, while they may seem appealing at a glance, do not contribute positively to the maintenance of steel survey chains. Storing them in direct sunlight can have damaging effects by causing temperature fluctuations that might lead to expansion and contraction, which could affect their integrity. Lubricating them with heavy grease could attract dirt and debris, which is counterproductive to the purpose of keeping them clean. Lastly, using them for all terrains without care can expose them to conditions that may lead to damage or wear, further shortening their lifespan and accuracy. Therefore, the practice of keeping steel survey chains dry and clean is the most effective way to ensure their proper maintenance.
