When you wash your bike, always remember to inspect the tires for wear and tear.
Bent rims can create small pinches that grow over time if tires aren’t properly inflated, so be sure to inflate your tires to recommended levels.
Start cleaning by knocking off any visible dirt with a stiff-bristled brush.
Then use a garden hose on low pressure to rinse your bike.
You want the water to trickle out rather than spray with force, because water under pressure can force grime into the chain and other moving parts.
For the same reason, never use a power washer or put your bike through a car wash.
