Water spot removal? - slee18 - 05-01-2013 09:11pm
What's the best stuff to remove water spots? A sprinkler decided it need to water the grass in the middle of winter

If regular car shampoo isn't removing them then you may need to use a fine polish.

Had a black car once that would show any sort of spotting. The water is, basically (no pun intended), PH alkaline. I found a light solution of PH acid, that is, white vinegar, did the trick.

Would a little bit of white vinegar help against water that holds a lot of calcium and thus leaves a lot of marks when it dries up?

Using a DI resin filter for the final rinse will stop any water spots. With no need to dry off the paint, just wash & go.

Where do I get a DI resin filter from?

I use a 8L resin vessel Filled with mixed bed DI resin (demineralisation resin) which will give you 0ppm water.
There are ones on the Market made for car washing, but these you have to bin after 20-50 rinses as the resin will change colour (depends on how hard your supply is).
DI filters are made for the last stage of Reverse Osmosis, but some companies have now cottoned on to this for car washing & sell them at much higher prices.
The softer the water, the longer the resin will last. For around £15.00 you can buy a ppm meter (or wait until the water spots return). Because Suffolk water is so hard, I use stored rain water which is then filtered & pumped so the resin will last for years.
Tip. Only use the filter for the final rinse, with a slow running open ended hose. Never use with a pressure washer.
The company I use to buy my filters from are http://www.vyair.com/scripts/prodView.asp?idproduct=145
You need to click on the "filled with resin" box, or it will turn up empty. I have spent many a hour looking over the Web & this one is the best/cheapest on the Market.
One of the golden rules of vehicle detailing is to touch the paint as little as possible. Not to mention the time saved on not having to dry off your car.

Usually, yes. That calcium is a very mild version of bird crap which is so "base" it will attack your finish. I'd give it a try. Remember, vinegar can be used to remove calcium deposits from faucets, etc.

Any reason why you can't use a Pressure Washer on low flow setting? My Karcher has a variable nozzle and I tend to use on low pressure to 'trickle off' the detergent as opposed to blasting it off....
I'm definitely quite keen to trying of these though as living close to the Mendip Hills, our water is very hard and will spot on almost any surface.
