What is the greatest cleaning spray ever, capable of cleaning any mess, no matter how severe, with a few simple squirts? Why, that's 409, a cleaning product that's a well-kept secret by earth ponies. Rarity has encountered a problem with the messiness factor of the Carousel Boutique, and Applejack has the solution. The question is, what happens when Rarity is given the ultimate in earth pony cleaning technology?

This is my 409-follower special that is my excuse to delay my 400-follower special. I assure you guys that I put more effort into the story itself than I did in making the magical aura around the bottle of 409.
