Ranked Performance
Pricing
Quick Answer
Based on ChemCX analysis of 25 wheel cleaner products, Armor All Extreme Wheel & Tire Cleaner combines hydrogen peroxide oxidation with alkaline chemistry - a rare dual-mechanism approach that tackles both organic stains and metallic brake dust. At $0.24/oz (half the category average), this targets DIY enthusiasts wanting aggressive chemistry without premium pricing.
What It Is
Armor All produces this ready-to-use wheel cleaner targeting mainstream consumers through mass retail channels. The formula uses alkaline chemistry to break down brake dust, road grime, and oil-based contaminants commonly found on wheels and tires. As a ready-to-use product, it requires no mixing or dilution—users spray directly from the bottle onto the surface, making it convenient for occasional cleaning without measuring or preparation steps.

Where It Lands
Without disclosed pH, this Armor All cleaner operates in chemistry darkness for the consumer. Most alkaline wheel cleaners fall between pH 9-13, with higher values delivering stronger degreasing action against baked-on brake dust but increasing risk to delicate wheel finishes. The "Extreme" name and "Danger" signal word suggest aggressive formulation, likely in the pH 11-13 range. This chemistry profile works well for monthly deep cleaning of heavily contaminated wheels but creates unnecessary risk for weekly maintenance where gentler pH 8-10 cleaners handle light dust without finish concerns.
At $0.24 per ounce, this positions as a budget option, sitting 50% under the category average of $0.48/oz. Compare to P&S Brake Buster at $0.19/oz for even lower cost, or step up to Optimum Power Wheel Tire Cleaner at $0.35/oz for disclosed chemistry and potentially safer formulation. The low price makes this viable for high-volume users accepting the formulation uncertainty.
How It Compares
Closest Alternatives
3D GLW Series Wheel & Tire Cleaner offers the same alkaline chemistry and ready-to-use convenience at a nearly identical price point.
P&S Brake Buster delivers the same alkaline wheel cleaning power at 21% lower cost per ounce. Professional detailers managing higher volume work should consider this for budget optimization.
Optimum Power Wheel Tire Cleaner costs 46% more per ounce but offers Optimum's premium formulation chemistry. Choose this if you prioritize brand prestige or specific performance characteristics.

How the Chemistry Works
Tetrapotassium EDTA
serves as the key active ingredient, functioning as a chelating agent that binds calcium, magnesium, and metal ions in water and brake dust. This prevents water spots while boosting the cleaning power of other ingredients by removing mineral interference. The chelation process essentially locks onto metallic contamination, and makes it easier to rinse away stubborn deposits that normal surfactants struggle to remove.The dual amphoteric surfactant system combines lauramidopropylamine oxide and myristamidopropylamine oxide to create excellent foaming and emulsification properties. Amphoteric surfactants are particularly valuable in alkaline formulations because they remain stable at high pH levels where other surfactants might break down. These amine oxides provide strong cleaning action while maintaining foam stability throughout the cleaning process.
Hydrogen peroxide adds oxidizing power to break down organic stains and discoloration on tires and wheels. The disodium metasilicate works as an alkaline builder, enhancing overall cleaning power while providing metal protection properties. Potassium hydroxide adjusts pH to create the alkaline environment needed for effective degreasing and soil removal.
What We Like
- Hydrogen peroxide oxidizer - breaks down organic brake dust compounds that surfactants alone can't remove, enabling single-step cleaning on heavily soiled wheels
- Dual amphoteric surfactants with metasilicate - combines gentle foam generation with aggressive alkaline degreasing, handling both light maintenance and neglected wheel cleaning
- Full ingredient disclosure with CAS numbers - lets you verify compatibility with specific wheel finishes and coatings before application
What to Know
- The DANGER signal word reflects serious eye damage risk. Wear safety glasses and nitrile gloves
- STOT RE 2 classification means limit to occasional use rather than weekly maintenance routines
- Metal corrosion warning applies to some wheel finishes—test on polished aluminum or chrome in an inconspicuous area first
Who Should Buy This
Buy this for occasional deep cleaning of neglected wheels with heavy brake dust buildup, or when you need grab-and-go convenience without mixing concentrates. DIY enthusiasts tackling monthly wheel maintenance will appreciate the afforable ready-to-use format. For frequent detailing or professional daily use, consider P&S Brake Buster's concentrate format for better economics.

Frequently Asked Questions
Is Armor All Extreme safe for coated wheels? The Danger signal word indicates strong alkaline chemistry that can damage ceramic coatings and anodized finishes. Test on a hidden area first, and avoid extended contact times on delicate wheel finishes.
How does Armor All Extreme compare to P&S Brake Buster? Both use alkaline chemistry for heavy brake dust removal, but P&S Brake Buster costs 21% less at $0.19/oz versus $0.24/oz. The formulations perform similarly on iron contamination, making P&S the better value choice for regular detailers.
Why does Armor All Extreme work on brake dust? The alkaline chemistry breaks down the metallic bonds in brake dust particles, causing them to release from the wheel surface. This same alkaline action dissolves road grime and oxidized brake residue that acidic cleaners struggle with.
Should I dilute Armor All Extreme Wheel Cleaner? This is a ready-to-use formula that cannot be diluted effectively. The alkaline chemistry is balanced for direct application - diluting reduces cleaning power without providing cost savings like concentrate products offer.
