I have spent years cleaning greasy rotors and squealing drums in my garage, and I have tested almost every solvent on the market. In this comparison, you will learn how a low-VOC option stacks up against a strict zero-VOC formula when tackling stubborn brake dust. We will look closely at their cleaning power, drying times, and compliance rules so you can buy the right can for your workshop.
CRC Brakleen 1003695 Brake Cleaner Spray Non-Chlorinated Low VOC
I recently used the CRC Brakleen 1003695 Brake Cleaner Spray Non-Chlorinated Low VOC to clear out a stubborn layer of grease on an old caliper rebuild. This classic formula comes in a standard 14 oz can designed to meet strict regional environmental laws. During my testing, the chemical mix dissolved heavy deposits quickly without relying on chlorinated solvents. The canister itself measures 9.25 inches in length and width with a 2.63-inch package height which makes it easy to stack on my garage shelves. While the packaging lists its sport type as boating, I find it works brilliantly on standard automotive hardware and trailer brakes. It has a fast evaporation rate that leaves the metal dry in seconds.
- Non-chlorinated low VOC formula meets regional environmental regulations
- Compact packaging with a 9.25-inch length and width for easy storage
- 14 oz single-can pack provides enough solvent for a full axle brake job
-
Multi-purpose application suitable for boating equipment and automotive parts
-
Dissolves grease and heavy oil deposits almost instantly
- Evaporates quickly to speed up your repair time
-

- Not compliant in states with zero-VOC mandates like California
Best for:
Home mechanics living in low-VOC states who need fast-evaporating, heavy-duty cleaning power for greasy parts.
Expert Opinion: This CRC formula remains a shop standard because its high-pressure spray combines with aggressive non-chlorinated solvents to blast away grease with minimal scrubbing.
Wurth Zero VOC Brake and Parts Cleaner
When I needed to comply with strict state regulations, I turned to the Wurth Zero VOC Brake and Parts Cleaner supplied by AquaNation. This California-compliant zero VOC formula uses an eco-friendly, non-chlorinated blend to remove heavy contamination safely. The 14 oz cans deliver a powerful stream of solvent that quickly dissolves stubborn brake dust, oily residue, and standard brake fluid. It is designed as a residue-free performance cleaner, so you do not have to worry about oily films ruining your new brake pads. Regular use eliminates brake squeal and chatter by stripping away the glazed debris that builds up on rotors over time. I tested the convenient 12-pack size which ensures I always have a fresh can within arm’s reach during big restoration projects.
- California-compliant zero VOC formula for maximum environmental safety
- Residue-free performance ensures clean metal surfaces without oily film
- Formulated to eliminate brake squeal and chatter by removing glazed contaminants
-
Sold in a convenient 12-pack size containing 14 oz cans for bulk shop use
-
Fully legal for use in all fifty states including California
- Excellent pressure out of the nozzle to blast away dirt
-
Safer for the user and the environment than traditional solvents
-
Dries slightly slower than low-VOC alternatives
- Requires a bit more physical wiping on heavily baked-on grease
Best for:
Professional shops and DIYers in California or other highly regulated areas who need an environmentally compliant bulk solvent.
Expert Opinion: Wurth has managed to create a highly effective zero-VOC cleaner that maintains excellent pressure, making it the safest choice for daily professional shop use.
voc vs non voc brake cleaner: Key Differences That Matter
Performance Comparison
Let’s talk about raw cleaning power. The low-VOC CRC spray acts fast, melting heavy grease on contact because its chemical carriers are highly aggressive. It evaporates in a flash. The Wurth zero-VOC spray requires a different approach. It relies more on the physical pressure of the aerosol to blast away dirt. Because the zero-VOC solvents are less volatile, the liquid stays on the metal slightly longer. This extra wet time actually helps break down thick, baked-on brake dust, but you might need to use a shop rag to finish the job.
Price and Value Analysis
When you look at the price tags, the value proposition shifts depending on your volume. The CRC option is sold as a single 14 oz can, which is perfect for a quick weekend project. However, buying individual cans can add up if you do a lot of brake jobs. The Wurth package comes as a bulk twelve-pack of 14 oz cans. This bulk option reduces the cost per fluid ounce significantly. If you run a busy garage or have multiple vehicles to maintain, the bulk zero-VOC package offers better long-term value.
Build Quality Comparison
The construction of the cans dictates how well the product performs under pressure. CRC uses a high-pressure nozzle that creates a tight, pinpoint stream. The can construction is sturdy, resisting denting when tossed into a metal toolbox. Wurth also features an excellent nozzle design that maintains consistent propellant pressure until the can is completely empty. The chemical stability in both cans is excellent, though the zero-VOC formula from Wurth is much less corrosive to nearby rubber seals and painted surfaces if you accidentally overspray.
User Experience Differences
Working with these two products reveals a massive difference in comfort. CRC has a very strong, sweet chemical odor that can cause headaches quickly if you do not have a fan running. It dries so fast that you barely have time to wipe the surface. Wurth has a much milder scent that is far more tolerable during a long afternoon in the shop. It leaves the metal completely bare and clean, though you have to wait an extra minute for the liquid to completely air dry before mounting your new brake pads.
Which Should You Choose?
If you live in a state with relaxed environmental laws and want to blast away grease instantly without wiping, buy the CRC Low VOC spray. It is the best choice for quick, single-axle repairs where fast drying times are your main priority.
If you reside in California or prefer to keep your shop free of harsh chemical fumes, the Wurth Zero VOC cleaner is your best option. It is also the ideal choice for professional mechanics who want to buy in bulk to save money.
In my shop, I keep both on hand for different situations. The CRC spray remains my go-to for crusty, oil-soaked suspension parts that need aggressive solvent action. For routine brake pad swaps and rotor cleanings, I reach for the Wurth Zero VOC cans to protect my lungs and ensure a residue-free finish. Both products get the job done, but the zero-VOC formula is the smarter, healthier choice for modern garages.
Frequently Asked Questions
Q: What is the main performance difference when comparing voc vs non voc brake cleaner?
A: Low-VOC formulas contain stronger chemical solvents that dissolve grease faster and dry almost instantly. Non-VOC or zero-VOC formulas rely more on high spray pressure to wash away contaminants and take slightly longer to dry.
Q: Is a zero-VOC brake cleaner safer to use indoors?
A: Yes. Zero-VOC cleaners emit far fewer volatile organic compounds, resulting in a much milder odor. You should still maintain decent ventilation, but your working environment will be significantly more comfortable.
Q: How does a voc vs non voc brake cleaner affect plastic and rubber parts?
A: Low-VOC formulas can melt or degrade sensitive plastics and rubber seals very quickly. Zero-VOC formulas are generally gentler on rubber components, though you should still wipe away any overspray immediately.
Q: Will zero-VOC brake cleaner leave a residue on my brake rotors?
A: High-quality zero-VOC products like Wurth are engineered to dry completely clean. They leave no residue behind, ensuring your brake pads can grip the rotor surface without slipping.
Q: Why are some brake cleaners banned in states like California?
A: Certain states regulate volatile organic compounds to reduce smog and air pollution. Formulas with higher VOC levels do not meet these strict environmental safety limits, making zero-VOC options mandatory in those regions.
Q: Can I use low-VOC brake cleaner to clean electric motor parts?
A: You can use it on metal motor casings, but you must keep it away from internal wiring. The strong solvents can dissolve the protective varnish on copper coils.
