Rinsing Dirt Off a Car - In a Hard Water Area

[Koln-RS]

Not a frequent visitor here, and not obsessive about detailing, but do like to keep my cars presentable.

So, Sunday I give the car a nice clean - all fine. Next day I'm out driving and, especially this time of year, it picks up a layer of wet grime. Now a quick hose down will remove this, but it will dry with a bit of a dull haze and has lost the fresh glaze it had when clean.

Is there something that I can rise it with that takes off the dirt but dries a bit brighter,without much time and effort?

Have a look for a DI Vessel. A few mates of mine use and swear by them though I have no experience myself.

Thread over on DW about them HERE

At this time of year, you're better off living with it until you can give the car a proper wash and dry.
If you really can't bare it, a DI vessel is your best bet, but it'll never remove all the dirt and still have that hazy look from the dirt that has managed to cling on.

Thanks, I'll take a look.
Any other suggestions?

OK, I've had a look at these 'DI Vessels' and sort of understand - a filter system that you connect to the water supply that 'purifies' the water?

But what determines the size of vessel required - i.e. rinsing 3-4 cars per week (and occasionally cleaning the windows) and how often does the filtration medium (or whatever it's called) need replacing?

thanks

Di vessels are great. If you're rinsing 3-4 cars a week then something like a 25L will probably last 6 or 7 months. When the water spotting returns you just need to replace the Resin.

I've ran a 25L for the last 7 months washing multiple cars a week, cleaning the driveway weekly and doing a yearly pressure wash of the house brick work and it's been fine. Would probably be fine for another month if I hand dried my cars but I prefer to let them sit in the garage with the heater on to avoid touching the paintwork.

Fullcleancenter is where I got mine and it was quite cheap compared to elsewhere. Will be collecting new resin for it tomorrow! Highly recommended.
