How to prevent the rusting of the sprinkler truck II: Check the humidity at the stagnant water

When the sprinkler is on the road, it is sometimes difficult to avoid taking some of the accumulated water. This will make it easier for the sludge to accumulate in places such as the bottom of the sprinkler. If this is not done promptly, it will allow the moisture to hide. Therefore, check the inner and outer edges of the hub, the frame, the key hole of the door, and the movable part of the wiper frame, and check the smoothness of the drain holes of the doors and body parts to prevent rust.
