Rain strips lubricant off your chain faster than anything else you'll encounter on a ride. Water works its way between plates, dilutes whatever protection you applied, and leaves bare metal grinding against bare metal while you're still miles from home. Wet lube exists specifically to resist that washout — Muc-Off formulates their Wet Chain Lubricant with a heavier, more tenacious base that clings to chain surfaces even when water is actively trying to displace it.

The formula uses vegetable oil as its primary base, derived from renewable sources rather than petroleum. That natural origin doesn't compromise performance — Muc-Off adds what they call Extreme Pressure Additives that coat the high-load contact points where rollers meet pins and plates meet each other. Those additives maintain a lubricating film even under the intense pressure that occurs during hard pedaling efforts, preventing the metal-on-metal contact that accelerates chain wear.

Penetration matters as much as surface protection. The formula is thin enough to wick into the internal spaces of each link before the carrier evaporates, leaving lubricant where it actually reduces friction rather than just sitting on the exterior. Once inside, the heavier base resists being pushed out by water ingress during wet rides.... Read More
