Some people suggest using rubbing alcohol (isopropanol) to clean fuel injectors because it is cheap, readily available, and has a very high octane rating. However, others argue that it is not very effective for hard deposits, and that gasoline is better for general grime. There are also concerns about the potential damage to rubber and plastic parts in the engine not designed for high alcohol content. Some alternatives to using rubbing alcohol include getting a professional injector clean or using a product like Sea Foam, which is designed to clean fuel injectors and is safe for engine components.

Isopropyl alcohol is better for cleaning fuel injectors
Isopropyl alcohol (IPA) is a better option for cleaning fuel injectors than rubbing alcohol. While rubbing alcohol can be used as a fuel injector cleaner, it is not very effective for hard deposits, and gasoline works better for general grime. Isopropyl alcohol, on the other hand, is a common ingredient in auto gas additives and has been used for this purpose for many years. It is also a better option than ethanol or methanol for water absorption.
Isopropyl alcohol is a secondary alcohol, which means it has minimal corrosion concerns as it is a weaker solvent than ethanol or methanol. It has a high octane rating of approximately 120, so it should not lead to detonation. Additionally, it is distilled/refined from oil, unlike ethanol, which is a fermented grain product.
When using isopropyl alcohol to clean fuel injectors, it is recommended to use 99% pure isopropyl alcohol, not diluted rubbing alcohol, and add about 100 ml to the tank twice a year. This can help to prevent issues caused by water in the fuel tank, as isopropyl alcohol can mix with water and then mix with gas. However, it is important to note that some sources suggest that an IV drip of water through a vacuum port is a better method for cleaning valves and combustion chambers.
There are also commercial injector cleaners available that contain isopropyl alcohol, such as Chevron Techron, which can be added to the fuel after every 1,000 miles. Alternatively, some recommend using Sea Foam, an EPA-registered product that will not harm engine components, seals, gaskets, catalytic converters, or oxygen sensors.
While isopropyl alcohol can be effective for cleaning fuel injectors, it is always a good idea to consult a professional or refer to the manufacturer's recommendations for your specific vehicle.

The benefits of using rubbing alcohol don't outweigh the risks
While rubbing alcohol (isopropanol) is cheap, readily available, and has a high octane rating, its benefits as a fuel injector cleaner do not outweigh the risks.
Firstly, it is not a very effective cleaner. While it may work well for general grime, it is not useful for hard deposits, which are better removed with gasoline.
Secondly, there is a risk of damaging the engine due to the high alcohol content in the rubbing alcohol. This can cause issues with rubber and plastic parts not designed for such high alcohol content, leading to potential engine problems.
Thirdly, the use of rubbing alcohol as a fuel injector cleaner may void warranties. While some sources claim that using 10% ethanol gas is fine regarding warranties, using higher concentrations in vehicles not designated as flex-fuel vehicles may be an issue.
Finally, there are alternative products specifically designed for cleaning fuel injectors, such as Sea Foam, which is EPA-registered and will not harm engine components, seals, gaskets, catalytic converters, or oxygen sensors.
In conclusion, while rubbing alcohol may be a cheap and accessible option, its limited effectiveness and potential risks to the engine make it a less desirable choice compared to dedicated fuel injector cleaning products.

The use of ethanol as fuel is more common in some countries
Rubbing alcohol, also known as isopropyl alcohol, has been used in auto gas additives for many years. It is a high-octane fuel, so it shouldn't cause detonation. However, it is not very effective for cleaning hard deposits, and there is a risk of damage to rubber and plastic parts. It is also important to note that not all vehicles are compatible with ethanol-blended fuels.
Regarding the use of ethanol as fuel, it is indeed more common in some countries than others. Here is some information on that:
Brazil is the second-largest producer and consumer of ethanol fuel globally, with a significant portion of its fuel consumption attributed to ethanol. Brazil has the largest and most successful biofuel programs, producing ethanol from sugarcane. In 2006, Brazilian ethanol provided 18% of the country's road transport sector fuel consumption, and by April 2008, it surpassed 50%. Brazil is considered to have the world's first sustainable biofuels economy.
Other countries that are notable consumers of ethanol fuel include China, Canada, India, Thailand, Germany, Argentina, France, Japan, and the United Kingdom. These countries, along with Brazil and the US, accounted for about 73% of global non-US consumption in 2018. Thailand, in particular, has been using 10% ethanol (E10) on a large scale and has introduced E85 flexible fuel vehicles.
In the European Union, ethanol fuel consumption has been expanding. In the Netherlands, regular petrol without bio-additives is being phased out due to EU legislation mandating a minimum fraction of non-mineral origin in fuel. While Germany and France have shown interest in E85 fuel, it has not gained widespread adoption due to legal and market-related challenges.

Sea Foam is an EPA-registered product that will clean fuel injectors
Sea Foam has been recommended by mechanics and engine owners for over 80 years to prevent and overcome common engine problems. It is a leading manufacturer of fuel and oil additives, and its products are designed to be easy for anyone to use. When using Sea Foam to clean fuel injectors, it is recommended to add 2 or more ounces of Sea Foam per gallon of fuel. The more Sea Foam you add, the better it cleans! For maximum cleaning, add a full 16-ounce can of Sea Foam to a low tank (2-3 gallons) and drive until almost empty before refuelling.
Sea Foam is a safe and effective alternative to using rubbing alcohol as a fuel injector cleaner. While rubbing alcohol is cheap and readily available, it may not be the best option for cleaning fuel injectors. Some people suggest using it to remove water from the gas tank, but this may not be a good idea. Additionally, rubbing alcohol may not be effective for removing hard deposits, and it could potentially damage rubber or plastic parts not designed for high alcohol content.
Isopropyl alcohol, which is found in many everyday products, can be used to clean fuel injectors. However, it is important to use 99% pure isopropyl alcohol instead of diluted rubbing alcohol. It should be added to the fuel tank in small amounts, about 100 ml, twice a year. This can help to prevent fuel line freezing in damp climates. Overall, Sea Foam is a more reliable and safer option for cleaning fuel injectors compared to rubbing alcohol or other home remedies.
