A chilly morning and just cleaned the bike. As recommended, I used cold water to not accelerate rusting, but damn my fingers are numbs now! Why cold water? Well hot water provides more activation energy for the oxidisation process, thus increasing speed of corrosion. Chemist geeks can read up on the details of reaction temperature dependency and the Arrhenius equation that governs it.
