Cleaning the bike on slushy days. It takes about 45 minutes to wipe it down properly. This includes:
- the entire frame
- the drivetrain, including getting in between the cogs and sticking your fingers in and around the crank
- the tires, the rims, the hubs and each and every spoke
Some days I can't be bothered, but I never let it go for more than two or three rides if it's slushy out. Luckily the asphalt is usually bare enough in the winter here that it isn't always an issue.
