Water softener

[Simpo Two]

Having given my new car its first wash yesterday before a show today, I was plagued with watermarks. Some of this may have been because I started trying to dry the car with a hot air blower but it was too slow and before I'd finished the back, the bonnet was starting to dry.

However, it got me wondering whether a water softener would help. I don't have room for a proper one but is there any type than could live in the garage and give hard water in > soft water out via hoses?

I have this and get approx 1 year use before the need to refill - washing 2x cars (approx 1x per week in the good weather, less often in the winter)
