content: See, thing is Chinese roads are notoriously dirty, gravel, dust, dirt everywhere. They dont clean the streets so much as just spray water on them so its not a particle dust storm. There is an e-bike garage next door and it's just amazing how many times they fix the problem with..   WD40. Big giant sized industrial cans of WD40. Which makes me think you're probably right though maybe a giant can of WD is mandatory.
