The separate spray nozzle can be used to apply Bike Cleaner or Chain Cleaner. The spray nozzle allows you to apply the cleaners uniformly and easily clean hard-to-reach areas.
The loose spray head fits Dynamic Bike Cleaner 1L, Dynamic Chain Cleaner 500ml and Dynamic Chain Cleaner 1L.
Pro tip: do not screw the nozzle too tightly onto the bottle, you can damage the neck of the bottle with this. Hand-tight is sufficient.
