The Boss goes straight on to grimy chains, cassettes and jockey wheels and issues filth its P45. It's a drivetrain specific cleaner but it’ll work on any bits on your bike that are properly caked with grease and grime.

STEP 1
Point hose pipe at bike. 

Fire H2O generously and make sure to get all the muddy bits good and soggy. 

STEP 2
Lash Dirt Juice across your whip giving a few extra squirts to the really muddy bits.

For best results always agitate the areas to be cleaned with a brush after application to help loosen soil and drivetrain grime. 

STEP 3
Finally, rinse with fresh water and reapply chain lube.

Admire your clean drivetrain, count the pennies you've saved in buggered bikes, go ride more.
