Getting the Most from your In-Bay Automatic Car Wash

In-Bay Automatic Car Wash Chemical CleaningIn an earlier post, we looked at the different types of water that a car wash operation might use, and how your choice of detergent is affected by them. But that article didn’t take into account the car wash system being utilized – like in-bay automatic car washes.

The in-bay automatic car wash is one of the most popular types around. But with it, some unique issues arise. Not least amongst them is which chemical cleaning detergent offers the best results, and what settings work best.

As you know, the in-bay automatic car wash runs back and forth over a stationary car, unlike the tunnel car wash which uses a conveyor belt to move the car. Because of the two-step car washing process, the machine itself works hard, so the type of detergent used can play a part in lengthening its life.

Considering the Two-Step Wash Process

In some quarters, the two-step car wash is seen as inefficient, with either too much water or too much detergent used. But there are some clear advantages, especially in touchless in-bay automatic car washes.

Usually, an acid detergent is sprayed on, followed by an alkaline detergent, with the resulting chemical reaction lifting off dirt and grime, helping to make the rinse all that more effective. Some now believe that the best procedure is the other way around, for two main reasons:

(1). alkaline detergent tends to work best on dry surfaces when allowed to dwell
(2). acid detergents help establish a low pH which makes drying easier

Touchless or Friction?

Whether the car wash system is friction-based or touchless-based has a say too. The difference might seem simply mechanical, but they do influence which chemical make-up works best.

In fact, the key difference is obvious when you consider that friction can physically pull dirt and grime off the vehicle surface, whereas the touchless system relies solely on chemistry to lift and remove.

For Touchless Washes:

High-quality detergents must be applied in the correct way to guarantee the best wash results. So, while the brand is important, the detergent can neither be too strong nor too weak if customers are to be satisfied.

Ideally, it is best to use soft water rather than hard water. This means removing the mineral salts and replacing them with sodium salts to create a grain-per-gallon (gpg) rate of less than 3.5. The water also needs to be applied in high pressure jets, so the power rinse setting is the best choice. Soft water helps to minimize the build-up of scale, which is good for maintaining nozzle pressure.

For Friction Washes:

It is recommended that an alkaline presoak be used. The reason is that it offers a certain amount of lubricity which helps to protect friction components. The hard surface cleaning surfactants also mean that the vehicle is cleaned to a high standard.

It is recommended that the presoak be a lesser strength alkaline than with the touchless system. This is because the friction lends that extra strength, so the chemistry need not be. A mildly acid or low pH second soap pass will help in the drying process.
