Understanding the pH Scale in Detailing

A Balanced Approach for Beginners

A surprising amount of misinformation is put out there regarding pH and its role in detailing. Some treat it like the holy grail of cleaning, while others dismiss it entirely. Honestly, the “Truth” lies somewhere in the middle. Understanding pH and the surfaces and stains or grime you are working on can help, but it’s not the sole factor determining a product’s effectiveness.

Let’s break it down …

The pH Scale: What It Is and Why It Matters

The pH scale runs from 0 to 14, with 7 being neutral. Anything below 7 is acidic, and anything above 7 is alkaline. In detailing, acidic and alkaline products have their strengths and weaknesses depending on the grime you’re tackling and the surfaces you are working on.

Let’s explore each:

Acidic Cleaners:
These work best on inorganic stains like mineral deposits, salt, cement, and limescale. Acidic cleaners interact with mineral-based contaminants, breaking them down into water-soluble compounds for easier removal. While some weaker acids, like citric acid or acetic acid, can also tackle certain organic stains like wine or sweat.

Alkaline Cleaners:
On the other hand, alkaline products are great for organic grime, such as bird droppings, mud, oil, grease, and other fatty residues. Alkalines react with oils and fats to emulsify the compounds so that they rinse away easily.

A Key Lesson: It’s Not About “Strong” or “Weak”

Here’s the thing: Acidity or alkalinity doesn’t automatically mean “better cleaning power.” It all depends on what you’re cleaning and the material you’re working on. Believe it or not, acidic and alkaline products often complement each other—and in some cases, enzymatic cleaners are the real MVPs.

Common Myths and Misunderstandings About pH in Detailing

Let’s clear up some of the biggest misconceptions around pH:

“High pH cleaners are always stronger.”
Not true. A high pH doesn’t guarantee better performance—it simply tells you that the product is alkaline. Consider what you’re cleaning before reaching for the “strongest” cleaner.

“pH-neutral products are always the safest choice.”
While pH-neutral products are great for minimizing risk (especially on delicate surfaces), their effectiveness depends on the situation. They’re not some magical cure-all for every cleaning challenge.

Instead of obsessing over pH, focus on these two factors.

The surface you’re working on (paint, glass, rubber, plastic, etc.).

The type of grime you’re trying to remove (inorganic or organic).

Stop Playing Chemist!

One of the biggest rookie mistakes in detailing? Mixing products blindly or ignoring dilution instructions. I get it—the temptation to “eyeball” ratios or whip up your own concoction is real. But trust me, this approach can backfire quickly. At best, you’ll waste product. At worst, you’ll cause damage to the vehicle’s surface—or worse, to yourself.

Here are three rules to nail every time:

Follow manufacturer-recommended dilution ratios. They’re there for a reason. (Glug, glug method = BAD!!)

Never mix chemicals you’re not a certified chemist. Combining the wrong products can result in ineffective cleaning or dangerous chemical reactions.

If you’re unsure, I’d suggest erring on the side of caution: A higher dilution ratio (more water, less product) is safer than more product.

Pro Tip:

Most detailing brands spend years and thousands (if not 100’s of thousands) of dollars perfecting their formulas. Trust the professionals who develop these products instead of trying to DIY your own chemistry experiment.

The Four Pillars of Effective Detailing: C.H.A.T

If you want consistent, solid results, shift your mindset away from obsessing over pH. Instead, think about CHAT.

Chemical: Use the right product for the job and material.

Heat: Warmer temperatures enhance chemical effectiveness.

Agitation: A little elbow grease goes a long way.

Time: Let the product dwell to maximize its potential (a hugely overlooked step!).

Balancing these four factors is how we get excellent results, without overcomplicating the process.

Final Thoughts

Starting out in detailing can feel overwhelming, especially with the sheer number of products, choices, and marketing, but it doesn’t have to be. Avoid getting bogged down in buzzwords and marketing like “high pH” or “pH-neutral.” These terms are helpful when used appropriately, but they shouldn’t distract you from what really matters:

Understanding your surfaces and materials.

Choosing the right product for the job.

Using proper technique and following manufacturer guidelines.

Remember, detailing is more than just applying the most potent chemical and hoping for the best—it’s an art form that requires balance, patience, and a little practice. Armed with this, you’re well on your way to becoming a skilled, confident detailer.

Keep things simple. Stick to the basics. And master “Technique,” which matters more than anything else.
