Cleaning a muddy bike: the method that spares your bearings

The danger: high-pressure jets

The pressure washer reflex is enemy number one for your bike. High pressure forces water (and mud) through the seals on hub bearings, bottom bracket and headset. Result: bearings that squeak and fail in a matter of weeks.

The right method, in order

1. Gentle rinse (watering can, low-pressure hose, or bucket). Loosens the worst mud.
2. Degreaser on the drivetrain (chain, cassette, chainrings, jockey wheels) — let it soak.
3. Brush + soap on the frame, top to bottom. A fine brush for the cassette.
4. Rinse on low flow, never aimed directly at hubs/BB/headset.
5. Dry (cloth + gentle rolling) — residual water causes rust.
6. Relube the chain immediately (the degreaser + water has removed everything).

Zones to protect

Relubrication: don't skip it A clean chain but dry rusts overnight and wears quickly. After drying, apply a "wet" lubricant (for wet autumn), link by link, then wipe off excess. This is the move that determines when you'll need to replace your chain.

Frequency After every really muddy ride for the drivetrain; a full clean every 2–3 weeks during wet season is enough for everything else.
