Brake cleaner can cause hazing and embrittlement of polycarbonate plastic
In some cases, the damage caused by brake cleaner may be temporary and can be remedied by adding oil or shine products to the affected plastic surface. However, in other cases, the damage may be permanent, requiring replacement of the plastic part. It is important to note that the use of heat or a hairdryer to remedy the issue may be risky as it can melt the plastic if not done carefully.
To avoid damage to polycarbonate plastic parts, it is recommended to research the type of plastic and test the brake cleaner on a small area first. If the plastic shows signs of hazing or embrittlement, it is best to avoid using brake cleaner on that particular type of plastic. Alternative cleaning solutions, such as contact cleaner or electrical contact cleaner, are less aggressive on plastics and can be used instead.
Additionally, it is important to exercise caution when using brake cleaner near plastic parts. Spills or overspray of brake cleaner onto plastic surfaces can result in unintended damage. It is advisable to syringe out excess fluid from reservoirs and avoid spraying directly onto plastic components to prevent potential issues. Taking these precautions can help minimize the risk of damaging plastic parts during cleaning or maintenance.
In summary, brake cleaner can indeed cause hazing and embrittlement of polycarbonate plastic. The extent of the damage may vary, and it is important to take preventive measures or opt for alternative cleaning solutions to protect plastic parts from degradation.

The wrong mix of solvents and plastics can weaken the plastic
Some solvents, such as diethyl ether, are very effective at dissolving plastics, while others, like turpentine, are incompatible with certain types of plastic, such as ABS. The type of plastic and the specific solvent must be carefully considered before use. For example, mineral spirits (paint thinner) are not suitable for HDPE plastic, and lacquer thinner should not be stored in any plastic bottle that is not specifically designed for solvents.
In the context of automotive maintenance, using brake cleaner on plastic parts can have adverse effects. Several sources indicate that brake cleaner can leave marks on plastic surfaces and cause "crazing", which is a weakening of the plastic. This crazing may be the result of the brake cleaner removing oil deposits and brake fluid, making pre-existing cracks more visible. Chlorinated brake cleaner, in particular, is noted for its potential to damage plastics and rubbers.
To avoid issues, it is recommended to use alternative cleaning agents, such as engine degreasers or concentrated degreasers like Simple Green or Greased Lightning, which are known to have no harmful effects on plastic and rubber. In cases where brake cleaner has been used on plastic, immediate cleaning of any residue is advised to mitigate potential damage.
Overall, it is crucial to exercise caution when working with solvents and plastics. The specific types of plastic and solvent must be carefully considered to prevent unwanted outcomes, as the wrong mix can lead to weakened or damaged plastic parts.

Brake cleaner can cause permanent marks on plastic
Brake cleaner is a powerful tool for removing brake fluid and other contaminants from brake parts, but it can also be harmful to certain types of plastic. In some cases, using brake cleaner on plastic can result in permanent marks or damage.
Brake cleaner contains chemicals that can break down the oils on the surface of plastic, which can leave marks or cause the plastic to become brittle and crack. These chemicals, especially in chlorinated brake cleaners, can be too harsh for some types of plastic and cause irreversible damage.
Some people have reported using brake cleaner on plastic car parts, such as the ignition, only to find that it leaves behind marks that cannot be wiped off. In other cases, the brake cleaner may cause the plastic to dissolve or melt, resulting in permanent damage that cannot be repaired.
To avoid permanent marks or damage, it is important to research the type of plastic you are working with and test the brake cleaner on a small, inconspicuous area first. There are also alternative cleaners available, such as MAF sensor cleaner or electrical contact cleaner, which are less aggressive on plastics and can be used when electrical wires are involved.
Additionally, it is important to exercise caution when using brake cleaner near plastic parts, as overspray can accidentally come into contact with plastic and cause damage. It is always better to be cautious and use an alternative cleaning method when dealing with plastic to avoid permanent marks or damage.

Chlorinated brake cleaner is particularly harmful to plastic
Brake cleaner is a powerful tool for removing brake fluid, dust, grease, motor oil, and other contaminants from metal brake parts. However, it is essential to exercise caution when using chlorinated brake cleaners, especially on plastic components.
Chlorinated brake cleaner is a type of brake cleaner that contains chlorine atoms within its molecular structure. These chlorine atoms enhance the solvent properties of the product, making it highly effective at breaking down and removing contaminants. While this can be advantageous for cleaning metal parts, the same properties that make chlorinated brake cleaner effective can also be harmful to certain materials, particularly plastics.
The presence of chlorine in the brake cleaner's formula can cause it to react with the plastic, leading to undesirable outcomes. In some cases, the plastic may become marked or discolored, as reported by several users who inadvertently applied chlorinated brake cleaner to plastic car parts. These marks are challenging to remove and may require extensive efforts, such as sanding and repainting, to restore the plastic's original appearance.
Furthermore, chlorinated brake cleaner can potentially dissolve or break down certain types of plastic. This can result in damage to plastic parts, rendering them unusable or compromising their structural integrity. It is crucial to identify the type of plastic before applying any cleaner, as some plastics may be more susceptible to the harmful effects of chlorination.
To avoid potential damage to plastic components, it is generally recommended to opt for non-chlorinated brake cleaners when working near plastic parts. Non-chlorinated alternatives are considered safer for use on plastics and can effectively remove contaminants without causing the same level of harm. Additionally, for electrical components or plastic parts near electrical wires, a MAF sensor cleaner or electrical contact cleaner is suggested as a gentler option.

Some alternatives to brake cleaner are engine degreaser and dish soap
Brake cleaner is a solvent-based substance used to clean the various parts of a braking system of grime, oil, and dust. It is also used to remove stubborn dirt and grime from fasteners like bolts, nuts, and screws, and can be used to clean the engine, metal parts, and brake disks. However, brake cleaner is often toxic and includes ethylene glycol, which is extremely dangerous and lethal when swallowed. It may also contain fluorocarbons, which are poisonous in gas form. Therefore, it is important to consider alternatives.
Dish soap is another alternative to brake cleaner that is readily available and inexpensive. It can be used to clean various car parts, including the engine, without causing damage. Hot soapy water can be used to clean discs, rotors, caliper external surfaces, and backing plates. Additionally, it can be used to clean engine parts without the need for specialised products.
Other alternatives to brake cleaner include baking soda, white vinegar, and lemon juice. Baking soda is an all-natural cleaner that effectively eliminates dirt and grime. It can be made into a paste with water and applied to a clean rag to wipe down brake components. White vinegar can be used by soaking a cloth in the vinegar and wrapping it around the dirty spot, leaving it overnight, and then wiping away any remaining stains. Lemon juice can be sprayed on liberally, left for an hour, and then wiped away. These alternatives are safer and more environmentally friendly options compared to traditional brake cleaners.
