Why Water Quality Is Important to a Spot-Free Car Wash

December 22, 2017 7:55 pm Leave your thoughts

It’s very common for water spots to be left behind after washing your car with regular water from a residential garden hose. The spots you are seeing are the results of hard water—mineral buildup that can range in size and visibility (often white or off-white splotches or rings)—which can remain on your car whether you let it air dry or lightly dry it with a towel.

To reduce the possibility of such water spots, take your vehicle to a professional car wash location. An exceptional car wash service will use the best equipment available to ensure vehicles leave looking shiny and sleek.

Since the quality of the water is an important factor when it comes to offering your customers a spot-free car wash, your business should consider using a commercial RO water system and commercial water softener in Cincinnati, OH. Here’s some important information regarding car wash water quality.

Hard water versus soft water

The hardness in water is in reference to the water’s calcium and magnesium content, while water softening involves removing these minerals and exchange them for sodium or potassium. Water hardness is often blamed for spots left behind after washing, but does this mean that using soft water will result in a spot-free car wash? Maybe, maybe not. While hardness is the result of the minerals calcium and magnesium, these do not make up the total mineral content, known in water treatment as total dissolved solids (TDS). With higher TDS comes more spotting.

The reason for car washing spots

Spots may occur on the surface of your car after the water evaporates. This is due to the fact that minerals in the car washing water are left behind, and thus they present as an unsightly residue. The car wash you choose should have low TDS water, and should be able to advertise that you’ll get a spot-free rinse with reverse osmosis water. With reverse osmosis, the TDS of water can be reduced by up to 95 percent.

Car washes and water quality

If you operate a car wash business, then you are aware that you need to have the right tools and equipment on hand. For instance, in order to ensure a spot-free rinse, you will need to have some sort of water purification system in place, like a water softener and a reverse osmosis (RO) system. The primary job of a water softener is to remove calcium and magnesium from the car wash water, and a reverse osmosis water system removes a majority of the other TDS. This prevents serious spotting after washing.

A lot of water gets used in a car wash, so it’s important to work with a reliable supplier, like Ultra Pure Water Technologies, LLC, who can handle this type of commercial application. After all, your car wash business’ equipment must get regular maintenance and service to ensure everything performs at optimal levels—especially your commercial water softener and commercial RO water system in Cincinnati, OH.
