Brake Cleaner Alternatives: Ditch the Harsh Chemicals, Not the Cleanliness

You hop in your car, put the pedal to the metal, and speed down the open road feeling carefree. That is, until you attempt to brake and barely slow down before nearly rear-ending the vehicle ahead! Yikes – it’s clear your brake pads could use some TLC. While brake cleaner may be your go-to for cutting through all that grime, those harsh solvents come with some serious downsides. Read on as we spill the tea on gentler brake cleaners so you can give your car some sparkling service without endangering yourself or the planet!

Here’s a quick answer:

Safer substitutions for harsh chemical-laden brake cleaners include acetone, denatured alcohol, mineral spirits, citrus degreasers, and Simple Green cleaners. For a homemade option, mix baking soda, dish soap, white vinegar and water. Test any new brake cleaner on a small spot first to check for damage before full use. Properly ventilate workspace and avoid contact with key brake components.

Pumping the Brakes on Traditional Brake Cleaners

Before we dive into the kinder, cleaner brake clearing options, it helps to understand why you may want to skip the classic chemical-laden cleaners in the first place! Many conventional brake cleaners include:

  • Chlorinated solvents – These can irritate eyes, skin, and lungs. No good when you’re down in the mechanics!
  • Acetone – This common solvent stings and dries out skin and nasal passages.
  • Methanol -Absorbing this via skin or inhaling it leads to nausea, vision issues, and headaches. Bad news!
  • Petroleum distillates – These can contaminate groundwater if spilled or improperly disposed of.

In addition to health hazards, that trusty red brake cleaner can is actually highly flammable and cause fires or explosions if you aren’t extremely careful while spraying brakes or near ignition sources. Yikes! Suffice to say, having a safer stand-in on hand is wise for both your own wellbeing and avoiding unnecessary environmental havoc.

Earth (and Mechanic) Friendly Alternatives

Luckily, there are a range of solid brake cleaning substitutes that get the grime off without the dangerous downsides! Let’s explore your options:

Green Cleaners Already on the Market

First up – a few pre-made cleaners to consider grabbing at your local auto parts shop or hardware store:

Acetone– Fast-drying – Readily available – Inexpensive– Highly flammable – Strong odor – Can damage some plastics
Denatured alcohol– Less flammable than acetone – Readily available – Inexpensive– Not as effective as acetone – Slower drying time
Mineral spirits– Less flammable than acetone – Safe on most plastics– Not as effective as acetone – Slower drying time – Strong odor
Citrus degreaser– Biodegradable – Less flammable than acetone – Pleasant odor– Not as effective as acetone – Slower drying time – More expensive
Simple Green– Biodegradable – Non-toxic – Safe on most surfaces– Not as effective as acetone – Slower drying time – More expensive
Homemade degreaser:– Eco-friendly – Customizable– Requires mixing ingredients – Not as powerful as some commercial options
  • Acetone: You can snag this solvent for cheap, though it is intense stuff. Use with extreme caution regarding flammability and be sure to ventilate your workspace well.
  • Denatured alcohol: Higher flashpoint than acetone makes this one safer, though slower to lift grease. Worth considering!
  • Mineral spirits: This substitute won’t ruin plastics and is gentler than hardcore acetone. Just beware the strong smell!
  • Citrus degreasers: If you dig that orange scent, these biodegradable cleaners are less likely to irritate. Costs a bit more though.
  • Simple Green: A Green auto product made from plant-based surfactants. Its non-toxic nature makes it garage-safe if you don’t mind a slower clean.

Whip Up Your Own Garage Concoction

If you’ve got some standard household cleaning items on hand, DIY a gentler brake scrub with:

  • Baking soda – Just a quarter cup of this mild abrasive works cleaning magic.
  • Liquid dish soap – Few tablespoon of the Dawn or other eco-friendly brand helps lift grease.
  • White vinegar – Half a cup helps dissolve gunk . The acid works but the scent fades fast.
  • Water – Use the warm stuff to really melt built-up grime away.

Mix up these inexpensive ingredients in a bucket or spray bottle. Apply your solution to brake parts using a stiff brush or lint-free rag. Let it set a few minutes before rinsing clean.

Caution: Don’t pour any homebrew cleaners directly onto your brake discs or pads!

Choosing Your Brake Cleaning Poison

We’ve outlined quite a few solid brake cleaning alternatives here. But what’s best for your own ride? Before grabbing any bottle of solvent, estimate:

  • Cleaning Power – Is your brake gunk minimal or thick layers of grease?
  • Your Workspace – Can it ventilate acetone fumes or do you need something gentler?
  • Vehicle Type – Will mineral spirits harm any plastic components? Best check!
  • Personal Preferences – Do you want something cheaper or a particular scent?

Consider your unique situation then pick the brake cleaner that fits your needs. Often it pays to have two options on hand – like intense acetone for tough jobs and simple green for maintenance.

Using Any Brake Cleaner Safely

While the above alternatives are gentler than mainstream brake cleaners, take care when using any solvent or chemical solution:

✅ Gear up – Wear solvent-resistant gloves, protective eyewear, and a respiratory mask.

✅ Ventilate – Open those garage doors or use a fan to prevent breathing fumes.

Test first – Try cleaners on unseen brake component spots to check for damage before going all out.

✅ Dispose properly – Never dump solutions down household drains. Bring to hazmat dropoff days.

Following some basic safety keeps you, your family, and the environment protected as you get those brakes brilliantly clean!

Give Your Brakes Some Green Lovin’

Now that you know about kinder brake cleaning alternatives, you can keep your vehicle’s brakes in top shape for safe stopping without endangering yourself or ecology. Whether you buy certain solutions or mix up your own, use care when applying and disposing. Here’s to greener options for cleaner brakes!


1. Are brake cleaner alternatives as effective as traditional brake cleaner?

The cleaning power of alternatives varies. While some natural options like citrus cleaners are not as potent on heavy grease, products with acetone or mineral spirits can clean nearly as effectively as traditional brake cleaner. Always test a new cleaner in an small, inconspicuous area first to ensure it meets your needs.

2. How should I dispose of used brake cleaner alternatives?

Never pour any used solvents or chemical cleaners down household drains. Check your municipal hazardous waste disposal to safely recycle used cleaner. Allow rags with cleaner residue to fully dry outdoors before disposing to reduce fire hazards.

3. Is it safe to use rubbing alcohol as a brake parts cleaner?

While not as effective in lifting heavy grease, 70% isopropyl alcohol can be used carefully as a brake cleaner substitute. As it has roughly half the flammability potential of acetone, exercise similar precautions regarding ignition sources and ventilation.

4. Are there any homemade brake cleaner recipes using baking soda?

Yes! An eco-friendly brake cleaning solution can be whipped up with baking soda, dish soap, white vinegar, and water. Mix a rough quart of this solution and use a stiff brush to work it into brake components before rinsing. Avoid pouring any homebrew cleaner directly onto brake pads.

5. Will brake cleaner alternatives harm my brake system?

All brake cleaning products should be initially tested on inconspicuous components to check for damage before full use. As long as you use the cleaner according to instructions and avoid direct contact with key parts like brake pads and rotors, quality alternatives will clean safely with no harm done.
