How to Monitor the Quality of Your Wash

Dec 15, 2017 at 1:56 PM

As our previous posts about chemistry quality, water quality, and dispensing quality have mentioned, there are a lot of things that can decrease the quality of your wash – and it's not always obvious when things go wrong. Consistent monitoring is required to make sure that your customers are always getting what they paid for. Train all of your employees on what to look for so that issues are identified promptly and employees feel they have an impact. Expect the same from your service providers. Keep records of routine maintenance and schedule maintenance reminders based on the manufacturer's recommendations.

Now that we've covered your chemistry quality and your water quality, let's talk about how to check that your dispensing is working properly. Like chemistry and water, the quality of your dispensing system is equally important in delivering a superior wash. How do I choose a system? When it comes to dispensing systems, there are four different types: 1. Injector: This is when the product is pulled by a vacuum suction into a water stream traveling through a small device. 2. Injection pump (electric or water drive): This is when product is injected into a water stream from a pump. 3. Hydrominders: This is when your product is premixed into a "sump" chamber or tank, then "delivered" via pump (most commonly air-operated). 4. Pressurized direct injection: This system works similarly to a regular injector; however, it uses the Venturi effect to mix the chemical and the water and uses a "booster pump" to regulate water pressure consistently. The accuracy of your dispensing system will have a large effect on  the quality of your wash. When considering dispensing accuracy, focus on dilution ratio as well as the consistency of the dosing. Pressurized direct injection is most likely to provide the most precise dilution ratios and consistent mixed solution volume. Water pressure can fluctuate, often during your high-volume wash periods; but a pressurized direct injection dispensing system will help control those fluctuations.

We know that having quality chemistry is a key factor in providing a quality wash, but your chemistry will not perform well if you are operating with low quality water. Since water quality affects both the quality of your wash and the quality of your customer experience, it's important to perform frequent water quality checks to ensure that you're running your wash at the highest level of quality possible. Here are some common issues that indicate a potential water quality issue: 1. Non-performing chemical If your chemistry does not seem to be doing its job, your water quality might be the issue. Check the hardness to see if your water is affecting your chemical. If it is, make sure that your water treatment system is working properly, and discuss your options with your vehicle care specialist. 2. Spotting If cars are exiting your wash with spots left from water deposits, it is time to do something about your water quality. A great way to avoid water spotting is to implement reverse-osmosis, also known as spot-free water, in your wash. This will help you control the quality of your water by removing total dissolved solids (TDS) from your final rinse water.
