Are you a car wash owner who’s ready to level up your car wash game with a presoak solution? A good car wash presoak solution can go a long way in making sure your customers’ cars come out clean and shiny. But with so many options available, choosing one can be hard.
There are key differences between high-pH alkaline presoaks and low-pH acidic presoaks, so it’s best to know which system will give your customers the best experience possible.
What Is an Alkaline Presoak During the Wash Process?
An alkaline presoak is a cleaning solution with a high pH level specifically formulated to break down organic soils and matter.
The alk presoak is applied to vehicles at the beginning of the automatic car wash process. It’s a vital component in the car wash presoak process and is commonly used in in-bay automatic and tunnel car washes.
An in-bay automatic structure typically consists of a single bay where washing equipment moves around a stationary vehicle. Once the vehicle is parked and positioned correctly inside the wash bay, nozzles mounted on a gantry or arch apply the presoak solution.
Many tunnel car washes include a presoak arch, which is usually an overhead structure shaped like a semicircle or a series of parallel bars. The car passes through the presoak arch as it moves along the conveyor or enters the wash bay. Nozzles on the presoak arch use high pressure to soap up the vehicle’s surface with the solution.
In both setups, the presoak works its magic by loosening and dissolving stubborn dirt, road film and grime. This makes it much easier to remove these contaminants during the subsequent washing stages.
Why Does pH Matter?
pH levels affect the performance of your car wash presoak. Just as there are high-pH alkaline presoaks, there are also low-pH acidic presoaks. Different soils and substances require different pH levels for effective removal.
High pH for Organic Soils and Matter
High-pH car wash presoaks are particularly effective against organic soils and matter, such as:
- Bird droppings
- Grease
- Oil
The active agents in high-pH presoaks break down the bonds in organic matter, making it much easier to remove them during the wash process. This leaves vehicles spotless and shiny, ready to impress even the most discerning car enthusiast.
Alkaline presoaks offer several advantages, including their ability to eliminate tough organic soils. However, some high-pH presoaks can be too harsh for certain vehicle finishes and have a high environmental impact. They may also struggle with inorganic soils and mineral composites, which is where low-pH presoaks are a game changer.
Low pH for Inorganic Soils and Minerals
Low-pH presoaks, also known as acidic presoaks, are designed to tackle inorganic soils and minerals, which include:
- Road grime
- Hard water spots
- Mineral composites like calcium and magnesium
Acidic presoaks dissolve inorganic matter to make them easier to wash away and may contain ingredients like hydrofluoric acid.
Acidic presoaks can break down hard-to-remove inorganic debris and restore shine to dulled surfaces. However, acidic presoaks can be too harsh for some finishes and hazardous if not handled properly.
How They Work Together
You can use both high-pH and low-pH presoaks to provide a comprehensive cleaning solution. The effective surfactants of both presoaks can tackle organic and inorganic substances, and you’ll be able to offer your customers the best of both worlds and ensure a thorough cleaning.
How Do You Choose Which Is Best?
Offering presoaks can be a great way to boost your business. But how do you know which to choose? Here are five tips:
- Assess the most common contaminants encountered in your area and choose a presoak with the appropriate pH levels.
- Consider the dilution ratio — the ratio of presoak solution to water — and select a product that offers a balance between cost-effectiveness and performance.
- Look for premium liquid presoak solutions with a proven track record of success and positive customer feedback.
- Opt for presoak solutions that are eco-friendly and biodegradable, minimizing the impact on the environment.
- Reach out to industry professionals for their recommendations based on your specific needs and car wash setup.
Should You Always Offer a Presoak Option?
Presoaks help ensure a thorough cleaning, which translates to happier customers and a better reputation for your business. However, there may be situations where a presoak car wash is unnecessary. For example, do you deal with vehicles that are already relatively clean? Maybe you work with a clientele that primarily has vehicles with minimal contaminant exposure.
In such cases, offering a basic wash package without a presoak can help you cater to a wider range of customer preferences.
