Cleaning your bike chain after winter salt exposure
Inspect before touching
30 seconds of inspection can save you a $200 cassette.
The test that matters is stretch. With a chain checker, 0.5% or more means the chain is done. At 0.75%, your cassette also needs to be replaced. Without a chain checker: pull the chain forward on the largest chainring. If you see a full tooth between the chain and the chainring, replace it.
Next, look at the links. Pedal backward slowly. If you find a link that skips or doesn't pass perfectly through the derailleur, it's "jammed" or bent. Orange surface rust comes off with degreaser. Rust between the rollers does not.

Remove the salt and old lubricant
Water alone does nothing. The salt remains stuck to the old lubricant, everywhere in the chain, and it takes a real degreaser to dislodge it.
The right product: a bicycle degreaser. We use the Muc-Off Bio Chain Degreaser ($26.29) or the Mint'N Dry ($12.99) for a tighter budget.
Quick method: apply degreaser directly to the chain, brush each section with a chain brush, turn the pedal to go around.
Clean method: the Muc-Off X-3 Chain Cleaning Kit ($64.99). You install it on the chain, pedal backward for 30 seconds, and the chain comes out clean.
Rinse and dry thoroughly
Never lubricate a wet chain, as this seals the water inside. It will rust from the inside without you seeing anything.
Rinse: lukewarm water, damp cloth or garden hose. Never use a high-pressure jet. This forces water into the bottom bracket bearings and chain rollers.
Dry: clean cloth, link by link, then 15-20 minutes in the open air. In a hurry? A hairdryer on low heat will do the job.
The test: the chain should be metallic gray, clean. Not black, not orange, otherwise, degrease it again.
Lubricate with the right product
Spring and fall, it's wet lube. Thaw, showers, puddles. Wet lubricant stays put despite the water. Our choices: Muc-Off Wet 120ml ($19.41) or Muc-Off All Weather ($17.99).
Dry summer, it's dry lube. Lighter, attracts less dust, keeps the drivetrain clean. We like Muc-Off Dry 120ml ($19.49) and Dirt Care DRY ($18.95).
E-bike: the motor doubles the torque on the chain, causing it to wear out 1.5 to 2 times faster. Forget wax-based lubricants. Muc-Off E-Bike Wet ($29.99) is designed for this.
Application: one drop per link, inside the roller (not on the outer plates). Turn the pedal 20 times. Wipe off the excess immediately with a clean cloth.
Finish the job: cassette, chainrings, pulleys
A clean chain running on a dirty cassette will become dirty again in 5 minutes.
Cassette: Wipe with a cloth between each sprocket. For stubborn deposits, a string passed between the sprockets dislodges grime like nothing else.
Chainrings: Use a cloth soaked in degreaser on each tooth. Pay particular attention between the chainrings: that's where the gunk hides.
Derailleur pulleys: The two small wheels accumulate all the black paste from winter. Use a toothbrush and degreaser. If the teeth are rounded, replace the pulleys.
