Nothing kinky

You need a hose. If you are one of those people who buys those useless hoses that kink as soon as you even contemplate washing the car, you deserve the pain and anguish it delivers. On a return trip back from Sydney we had to wash the old Moffat race car transporter with one of those anaemic things. Never again! Get yourself a good quality medium strength hose. Not too tough so it's inflexible, not so weak that it's, for lack of a better word, kinky.
Don't worry about a fitting on the end. If you want to spray, which you most certainly do at the start, jam your finger in front of the hose, propelling the water at a more rapid rate. If you want a gentle, even flow, which you do at the end, remove your finger and let it flow.
