Whats the easiest way to clean my bike? Simple question, however, I am used to cleaning my bike at my parents house, I use some eco bike spray stuff leave it for a little then rub and hose down (I normally get it quite dirty riding down dirt tracks in West Sussex, UK).

I am now at University and our flat has no access to a garden or hose pipe, the best place / possible way I can think to clean it is out on the pavement next to a busy road with a tub of water and a sponge.

Would anyone recommend taking their bike to a garage and jet washing it down? Anyone found a really easy way to clean their bike with limited space?

Don't forget to TF2, thanks.
In the winter when the garden hose is disconnected I use a watering can filled with warm water to wash the dirt/salt off the bike before taking it in. I use mild detergent soap to speed up the removal of oil and grease then pour the warm water from the can to remove the soap.
