This rejected water may be recycled and used early in the wash process or elsewhere at your wash, but remember this water contains higher mineral content. I’d never used a water filter on my car before but it’s one of those things from which I’ll never go back. With soft water you can achieve better results with less chemical, and that means lower chemical cost per car. You can see from these figures that by simply using a taller thinner filter you significantly increase the capacity of the unit from 59 litres of water per litre of resin with the 6×18 to 79 litres of water per litre of resin with the 6×35.

Softening” in the conventional sense means removing these minerals by exchanging sodium or potassium for them.You’ll drive yourself crazy figuring out how to sort out the water spots problem if you continue to use the same water.

The picture in the quote does not appear in the original reply (at least it doesn’t in the GJ App on my phone).Soft water is the best choice to use with detergents and presoaks, as you'll be able to use less soap and still get a clean rinse. Used the filter this weekend to wash and rinse completely all the motorhome at once left it to dry excellent perfect finish no water spots or streaking, completed the job in less half the time, used to take almost six hours. International Filter has extensive experience providing water treatment systems to the car wash industry. The trickier bit is getting the new resin into the vessel, but again, if you take your time, you can pour it in direct from the bag it comes in, tamp it down by tapping the filter on the ground and just do it up again. You could run a spur to the garage to use hard water, but since the water is softened prior to heating via a boiler or immersion tank , the hot water will be soft unless you provide a separate facility to heat the mains water in the garage.

However, hardness represents only a part of the mineral content of water—the calcium and magnesium ions. We’ve tasked one of our staff members to take home a Pro+Aqua Travel Series 16,000 Portable Water Softener and use it with his pressure washer to wash some vehicles in his household.These minerals prevent soaps from working properly because they in effect block the ability to create lather. The AquaHouse DI Car Wash water filter leaves your car with no water marks or streaks when used to rinse after cleaning. However, doing so only creates soap scum as well as using too much of it, which is a waste of money. Washing both a big car and a black car in a hard water area has never been straight forward: Water-marks would appear on one side of the car by the time I’d finished rinsing the other side! A wash bucket gritguard wont filter out the fine granules of grit off your roof, you'd have to filter it through fine gauze to do that, but if you rinse off with rainwater, why bother drying off with a towel after anyway ?

Hard water causes limescale formations on cars because of its rich mineral content, so it might not be the best option for car washing.

Known for incredibly small pore size membranes, reverse osmosis filtration systems produce the highest form of purified water. I also use my exhausted 0ppm filter in line with a new 0ppm filter to prolong the new filter life – it works a treat!
