What You'll Learn
Bleach is mostly water, which corrodes metal
Bleach is mostly water, and the rest is mostly sodium hypochlorite. Bleach also contains a small amount of chlorine, which makes it corrosive. When bleach is added to a diesel tank, the chlorine will pre-burn into the fuel before it gets to the engine. This can cause serious damage to the engine, fuel tank pipes, and gasoline tank.
The corrosive effect of bleach on engine components and fuel systems is grave and faster than normal corrosion. The fuel lines, tank, pump injectors, cylinder head, and intake manifold will all be affected. Bleach can also leave harmful sludge inside the valves and combustion chamber.
The rate at which different metals corrode varies. For example, pure iron will corrode quickly, while stainless steel, which contains iron, corrodes much more slowly. A group of metals known as noble metals, including silver, platinum, and gold, rarely corrode. However, they are expensive and therefore sparingly used in water systems.
The growth of microorganisms within water systems can also cause extensive corrosion. MIC refers to corrosion caused by bacteria and the by-products of bacterial growth reacting with metals. While not the sole determinant, the pH of the water can influence corrosion rates. Iron and steel corrosion rates are stable within a pH range of 4.5 to 8.5, while protective zinc coating in galvanized pipes corrodes when the pH is less than 6.5.
When two dissimilar metals are coupled in a water environment, the less noble metal will corrode in favour of the more noble metal. For example, steel fittings coupled with copper pipes will corrode because steel is less noble than copper.

Bleach's chlorine content makes it caustic
Bleach is a chemical compound that is diluted and sold for household use. It is a mixture of water and sodium hypochlorite, with the latter present in concentrations ranging from 3 to 9 percent for household use and 30% or higher for industrial applications. The chlorine content in bleach, albeit small, is what makes it caustic and corrosive.
The caustic nature of bleach is due to the presence of chlorine, which is a powerful oxidizer and the active agent in many household bleaches. Chlorine is a toxic and corrosive gas in its pure form. Therefore, household bleach products typically contain hypochlorite, which releases chlorine. This chlorine content is what makes bleach effective at whitening or colour-lightening materials and surfaces. It breaks the chemical bonds of chromophores, rendering them non-reactive to light.
The corrosive nature of bleach is well-known, and it can irritate or burn skin, eyes, and mucous membranes. The vapours from bleach are also irritating to the eyes and respiratory system. When mixed with other chemicals, such as ammonia, bleach can produce toxic gases like chlorine gas, which can be deadly. Bleach should never be mixed with other household cleaners, especially those containing ammonia, as this can lead to the release of chlorine gas and cause asphyxiation.
When bleach is added to a diesel fuel tank, the chlorine in bleach can react with the additives in the diesel, potentially deactivating some of them and reducing protection for the engine. The corrosive nature of bleach can also cause damage to the fuel tank, fuel lines, pump injectors, and other metal and rubber components of the engine. Even a small amount of bleach in diesel fuel can lead to costly repairs and engine problems.
To summarise, the chlorine content in bleach makes it caustic and corrosive, which is why it is effective for whitening and disinfecting purposes. However, this same property also makes it dangerous if not handled and used properly, especially when mixed with other chemicals.

Bleach damages fuel's lubricating properties
Bleach is a highly corrosive substance, composed mainly of sodium hypochlorite. When bleach is introduced to a car engine, it can cause extensive damage. Bleach can cause corrosion in the fuel tank, and the pipes and injectors of the fuel system. The corrosive effects of bleach can also damage the engine's rubber seals and gaskets, leading to leaks of vital fluids such as coolant, oil, and transmission fluid. This can cause a chain reaction of damage, destroying other engine parts.
The chlorine in bleach will react with the fuel, burning out and becoming a corrosive oxidizer. This will cause a reduction in performance and increased fuel consumption. The more bleach that is added, the more severe the effects. Even a small amount of bleach in the fuel will cause changes, and the car will eventually stop running.
The corrosive nature of bleach means that it can eat away at metal and rubber components over time. This includes fuel lines, the fuel pump, the fuel tank, and injectors. Bleach will also contaminate the engine oil and coolant, causing a reaction that produces undesirable byproducts. This contaminated oil will not lubricate the engine properly, increasing friction and reducing the lifespan of the engine parts.
The long-term effects of bleach in a fuel tank are worse than the short-term effects. It is important to act quickly to repair any damage caused by bleach. The engine should be flushed, and contaminated parts replaced.
