How to maintain the valve caps?
To avoid the valve caps' natural oxidation and corrosion, we should maintain the valve caps with the following methods.
1, Avoid long time exposure of the valve caps to water or snow.
2, To unscrew and clean the valve caps, and to check the tire pressure on a regular basis, say 2-4 weeks/once, so as to prevent the oxidation of the valve cap threads and ensure the tire pressure normal.
