Go to your local auto parts store and pick up a can of silicone spray. This one only cost about $2.99.
Then spray it all over your frame to make it all shiny and purdy. The silicone leaves your bike clean and it helps repel dirt and water. It also makes it easier to clean your bike next time.
Alot of the bike polish products out there like Finish Line, and Pedro’s Bike Lust have silicone in it. But those products can cost up to $10! But with this alternative, you just saved yourself at least $7.
