Water Softener Use In Mobile Auto Detailing

What is considered hard water and what are the degrees of hardness? Well very hard water would be 10.5 grains per gallon and 180 parts per million and above. But you need to realize that even moderately hard water of 3.5 to 7 grains per gallon and 60-120 parts per million will leave hard water spots. Slightly hard water such as 1 to 3.5 grains per gallon and 17.1 to 60 part per million will not leave noticeably hard water spots that you can not cure with a chamois. But really as a professional auto detailer you are really looking for soft water of less than 1 grain per gallon and 17 parts per million.

What Makes The Water Hard?

Hardness in water is caused calcium and magnesium ions that form insoluble compounds; sometimes iron and even aluminum. There are many ways to soften water. Some are more complicated than others; Aeration, De-Ionization or ion-exchange, Distillation, Reverse Osmosis or Softening.

Softening by use of a water softener is the simplest concept used today; water softeners replace hardness ions like calcium and magnesium with sodium or non-scaling ions. The ion exchange resin used in the process is recharged periodically with salt drawn from a storage tank. Many water treatment experts agree and Lance Winslow concurs that softening can be most cost effective when the water has as few as one to five grains per gallon of hardness. Most mobile operators will be happy with one to three grains per gallon of hardness and probably will not even purchase a softening unit until the hardness is five plus grains per gallon. Their theory is well taken because, if the total dissolved solids (TDS) is that low, there will be little water spotting on cars anyway.

One reason to put in a water softener even if your water is 5 gpg or less is because you wish to prevent scaling in the coils of your steam cleaner or save your pressure washing pump on your auto detailing rig. On a cold water machine, this is not as important because 5 gpg or less will not ruin a pump. More than five can over time.

Hardness also hinders soap from doing its job. You may notice that your soaps are not cleaning properly. That's because they are cleaning the water first and combining with the compounds in the water rather than the dirt on the car. You see, the hardness in the water has a tendency to neutralize those cleaning compounds and you have to actually use more soap to offset the neutralizing effect of the hardness minerals.

With hard water, you will use more soap and the cars still are not clean. I encourage you to talk to your soap vendors for helpful advice on water chemistry and treatment requirements. Your soap strategy should be custom tailored to your city and the hardness of the water you put in your tank.

Most independent auto detailing professionals agree that areas with hard water will …
