A good, and often misunderstood, option is rinseless washing. Optimum No Rinse is a product designed for this kind of situation. Being a completely different technique to the usual safe wash method it can feel a little off, but once you get used to it it can become a very handy solution to your issue.
Note: This isn't an option when the car is heavily soiled
As Mainframe has said Koch Chemie Green Star is an amazing product. At about £5 a litre it really can't be beaten for value and added to that the fact it is best used diluted then you're really on to a winner.
I'm aware of some do-it-yourself pressure washers at Tesco offering filtered water, but I would be surprised if it was common place across other garages.
To announce the launch of our new 2ltr pressure sprayer we thought we would run a little comp for your chance to win one.

We had a customer say that they occasionally rinsed there's under a warm shower head.
And yes its all about the care, treat it like you would a wool jumper; don't snag it, rinse it thoroughly and NEVER force dry it.
