"How often should I clean my bike?"

While the answer to this question is broad, as it depends on where the bike is ridden and through what conditions. A clean bike is truly a happy bike. As a general rule of thumb, if you get back from a ride and your bike is muddy and is gritty are good grounds to clean it. By removing the mud and grit from the bike, especially from the drivetrain, prevents pre-mature excessive wear-and-tear. Similar to how you may find smooth pieces of ocean glass along a beach, grit does the same thing to your drivetrain and wears down at the outer surface of parts (this can typically result in a noisy drivetrain, your chain dropping, and skipping of gears). 

"How should I clean my bike and with what products?"

Targeted Part(s)	How to Apply the Product:	Product
The chain and cassette	Simply follow the instructions provided by placing the highlighted amount of cleaning solution in to the handheld-chain cleaner. Once done, carefully snap the device over the chain and proceed to spin the drivetrain.  The brush and pick are handy to get stubborn grit and grease out of the cassette, chain, and jockey wheels.
The cassette	If you find the cassette is quite greasy and gritty, sometimes it is easier to remove the cassette to clean the cogs more thoroughly. To do this, you need either a chain-whip and cassette lock ring tool (for freehub wheels) or a freewheel removal tool.
The frame, wheels, drivetrain	This product is a good all-around cleaner that can effectively and efficiently remove grit and grime from your bike. It comes with a handy spray applicator which can be applied directly onto the bike or onto a micro-fiber or lint free cloth.
The chain	To ensure your bike is running smoothly requires a well lubricated drivetrain. There are a few different types of chain lube that's available, each corresponding to preforming well within certain conditions and environments. For example, dry lube is most commonly used on road bikes and performs optimally in dry conditions. In contrast, wet lube is used more commonly on mountain bikes, cross bikes, and hybrid bikes as it performs optimally in wet and adverse weather conditions.
