The visor on my helmet gets cleaned about twice a year. It's kind of nasty. Last night, I broke out the high-powered cleaning fluid and chipped every last insect carcass off my window to the world.
I also cleaned and oiled my chain. My chain isn't neglected like my visor, but it was getting a little noisy.
Riding in to work on a cool, gloomy morning with a clean visor and near-silent chain? Heavenly.
