How to

Step 1

Start by rinsing your ride with clean water. 

You can apply Dirt Juice Boss using a Dirty Little Scrubber chain bath, paint it on with a brush or fill a shallow container and dip your bits in. 

Leave Boss to soak for 5 minutes… Just long enough to make a cuppa.

Step 2

Once the Boss has soaked for a couple of minutes, give your drive train a good scrubbing with a soft brush. 

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.
