Dealing with very hard water?

You what?

HE GOT A HOSEPIPE BAN!

Deaf b'stard. :rofl:

:lol: :lol: :lol:

The lengths (and expense) people go to are truly astonishing IMHO. :roll:
Using a sledgehammer to crack a walnut springs to mind!
I've lived in extremely hard water areas all my life (and current location is very very hard).
As long as you dry a car with a microfibre towel before the water evaporates there is no problem with limescale IME, especially if it is waxed every once in a while.

As for removing 'baked on' scale, I would use a very diluted limescale remover, then rinse and keep repeating it until the residue has been dissolved.
T-cut will shift it aswell, if it's really cooked on!

A company called Raceglaze makes water filters of varying sizes which connect to you hosepipe and the rinse the car. The filters are filled with resin which you replace every two years.
When youhave done the usual washing etc give a final rinse with water passing through the filter. There is no need to wipe dry. Just leave to air dry and the car will be spot free. Even windows dry clear. Not cheap but works really well.
I have just received my replacement refill and will doing it this week.
All the info is on their website.
Hope this helps.

Interesting...are you using the 7 litre version and how long before replacing the granules?

I bought the bigger 14litre version and mounted it on an old sack trolley so it stays upright and is easy to move. The granules have lasted just over 2 years. I have only recently replaced them. Most weeks I have used it to rinse two cars after washing them. Not cheap but works really well. I am glad I bought it.

I use a Raceglaze water filter aswell. Great piece of kit and totally eliminates water spots.

I use two in serial. That way, you are not throwing the product away until it is really buggered. The second vessel takes the worst out and then the other one has less work to do

Really good idea. Never thought of doing that.

My z4 got watered one time while it was parked at my ex InLaws and the gardener watered the lawns… :headbang:

It was really bad and the paint was perfect, I managed to get 95% off with Chemical Guys Speed Wipe Quick Detailer and then Zanio Z6 Quick Detailer….

For hard water as others have said I use a RI resin Vessel…. For the Z4 I even use that water to wash it too…. If you can finish rinse with water from the hot tap that would reduce a lot… you get more spotting from the direct cold main pressure….

I use filtered rain water to wash my cars - 3 water butts in series with filters then run the pressure washer off the last in line - works a treat and no arguments when a hose pipe ban comes into effect.
