What is Brake Cleaner and Starting Fluid?

Before we delve into whether brake cleaner can be used as starting fluid, let’s first understand what brake cleaner and starting fluid actually are. This will give us the necessary foundation to tackle the question at hand in a comprehensive manner.

Brake Cleaner

Brake cleaner is a powerful solvent-based cleaning agent designed specifically for cleaning and degreasing brake components. It is formulated to quickly dissolve and lift away oil, grease, brake fluid, and other contaminants from brake linings, calipers, rotors, and drums without leaving any residue or affecting the brake’s performance. The composition of brake cleaner varies, but it generally contains one or more of the following chemicals: acetone, toluene, methyl ethyl ketone, and other volatile organic compounds.

Starting Fluid

Starting fluid, also known as engine starter or quick start fluid, is a combustible aerosol spray used to assist in starting internal combustion engines, particularly in cold weather or after long periods of inactivity. This highly flammable fluid contains various hydrocarbons, such as ether, propane, or butane, which are easily vaporized and ignite quickly when exposed to a spark or heat source. It is designed to provide a brief but intense burst of flammable vapor to aid in the ignition of a stubborn or cold engine.

Differences Between Brake Cleaner And Starting Fluid

Brake cleaner and starting fluid are often mistaken for each other, but they serve different purposes. Let’s delve into the distinctions between the two.

Brake cleaner typically contains chemicals like acetone, toluene, and petroleum distillates. Conversely, starting fluid mainly consists of ether compounds, offering explosive properties for quick ignition.

Brake cleaner is designed to clean brake parts, remove oil, dirt, and contaminants, while starting fluid is formulated specifically to aid in starting engines in cold conditions by providing a combustible boost.

Can Brake Cleaner Be Used As Starting Fluid?

Brake cleaner should not be used as a starting fluid as it is not designed for that purpose. Using brake cleaner as a starting fluid can damage your engine and compromise its performance. It’s always best to use the proper starting fluid recommended by your vehicle manufacturer.

Potential Risks

Using brake cleaner as starting fluid can lead to severe engine damage. It contains chemicals that are not meant for combustion and can cause harm to engine components.

Brake cleaner is not designed to be ignited like starting fluid. Trying to use it in place of starting fluid can result in dangerous situations and unsafe engine operation.

Effects On Engine

Applying brake cleaner to the engine can leave residue that may interfere with proper engine function. It can cause build-up and contribute to engine malfunction.

In the long run, using brake cleaner as starting fluid can lead to decreased engine performance and potential breakdowns. It is not a suitable substitute for starting fluid and should not be used in this manner.


  • Invest in a proper starting fluid specifically designed for engines
  • Keep your engine clean and well-maintained to avoid the need for shortcuts
  • Consult with a professional mechanic for safe starting methods

Safe Handling And Usage Tips

When using brake cleaner as a starting fluid, it’s crucial to prioritize safe handling and usage. Following proper guidelines can ensure your safety and the effectiveness of the product. Here are some important tips to consider for the safe handling and usage of brake cleaner as a starting fluid:

Proper Storage And Disposal

It’s essential to store brake cleaner in a cool, dry place away from direct sunlight and sources of heat. As the canister is pressurized, store it in an upright position to prevent leaks or spills.

Dispose of empty brake cleaner cans appropriately, following local regulations for hazardous waste disposal. Do not puncture or incinerate the cans, as they may explode if exposed to high temperatures.

Safety Precautions

  • Do not use brake cleaner as a starting fluid near open flames or sparks, as it is highly flammable.
  • Always maintain proper ventilation when using brake cleaner to prevent inhalation of fumes. Consider using it in well-ventilated areas or wearing a mask if necessary.
  • When using brake cleaner as a starting fluid, avoid prolonged skin contact to prevent irritation or chemical burns. Wear protective gloves if needed.
