Can You Use Brake Cleaner As Starter Fluid?

January 2023 · 2 minute read

If you’re in a hurry and need to get your vehicle started quickly, there are some things that can help. One of them is called “starter fluid.” Starter fluid is a petroleum-based product that contains ether, which increases the volatility of gasoline.

Ether evaporates more quickly than gasoline alone and produces greater pressure within the cylinders as it does so. Using starter fluid when starting an engine cold makes it easier because it lowers the temperature at which vaporization begins (therefore increasing the likelihood that ignition will occur).

Starter fluids

There are a few different products called “starter fluid.” Some of them are solvents, but if you’re looking for an actual starting fluid, make sure to check the label. 

Ether is a good choice if you have it on hand; it’s easy to find and can be used without any dilution. However, ether can be extremely flammable so you should only use it outdoors or in an open space with proper ventilation when possible.

Starting fluid is another popular option that contains ether along with other components such as alcohols and dimethyl ether (DME). 

Brake cleaner also contains DME but typically lacks the solvent properties of starting fluid—it’s usually used for cleaning brake parts instead of starting engines. You may want to avoid using either type for this reason unless there’s nothing else available in your area!

Brake cleaner as a starter fluid

Using brake cleaner as a starter fluid is dangerous. Brake cleaner is flammable, and it will explode if you accidentally backfire your engine while using it. This can cause injury to anyone nearby and damage or destroy the car.

The best choice for starter fluid is ether, which has been used for decades for this purpose. Ether is less toxic than other options and doesn’t cause nearly as many explosions when it comes into contact with sparks (which are common during normal combustion).

Conclusion

So, can you use brake cleaner as a starter fluid? The answer is no. It may work for a few seconds, but it will be harder to start your engine next time and could cause permanent damage to your catalytic converter.
