Qingdao iron fence experts said that in fact, this does not have much impact, if you encounter this situation, after the rain stops the water on the fence with cotton cloth can be wiped clean, because the cast iron fence itself has a layer of protective paint to protect.

However, if you are still not at ease, you can rub a layer of anti-rust oil on the surface of the fence, but do not use hard things to wipe and bump the guardrail.

I hope the above introduction has been helpful to you.
