STEP 1
Give your bike a wash.
Fire H2O generously and make sure to get all the muddy bits good and soggy.
STEP 2
Get a load of Dirt Juice Boss on your cassette, chain, chainrings and get Stiffling.
Use the Stiffler to work Boss into your components and give that grime a good rubbing up.
For detail work you can add some Boss to a small container and paint it on to components.
STEP 3
Rinse brush and components with fresh water.
Scrub, rinse, repeat and then apply your favourite chain lube to finish.
