What You'll Learn

Brake cleaner can disintegrate or break down plastic
Brake cleaner damages plastic materials by targeting the components that bind them together. The use of chlorine compounds in older brake cleaners, such as tetrachloroethylene, has been banned due to their ozone-depleting effects. Modern non-chlorinated brake cleaners are made of aliphatic or aromatic compounds and polar solvents, which can still be harmful to plastic.
When brake cleaner comes into direct contact with plastic, it can cause the material to disintegrate or break down. This is because the chemicals in the brake cleaner attack the bonds that hold the plastic together. As a result, the plastic becomes brittle and can easily break or shatter.
To avoid damaging plastic parts, it is recommended to use alternative cleaning methods or products specifically designed for plastic, such as engine degreasers or concentrated degreasers like Simple Green or Greased Lightning. These products can effectively clean plastic surfaces without causing harm. Additionally, users should always test new products on a small area first to ensure they do not cause any unexpected damage.
It is important to note that brake cleaners can also be harmful to other materials, such as rubber, and can cause skin and eye irritation. Therefore, it is crucial to take the necessary precautions, such as wearing protective gear and ensuring proper ventilation, when using these chemicals.

It can damage the skin
Brake cleaner is a solution used for cleaning brake disks, engine parts, and other metal components. It is not advisable to use it on plastic surfaces as it can cause permanent damage.
Brake cleaner can damage plastic by targeting the components that bind plastic materials together. Initially, the plastic surfaces appear intact, but over time, they turn brittle and develop fractures and cracks. This is because the cleaner contains methyl acetate and aliphatic or aromatic hydrocarbons, which can cause the plastic to disintegrate or break down.
The damage caused by brake cleaner to plastic is not limited to car parts. It is also harmful to most plastics, which is why it is usually packaged in metal spray cans. This means that if you get brake cleaner on your skin, it can be harmful.
Brake cleaner can damage the skin if exposed for a long time. Therefore, it is important to take precautions when using this product, such as wearing protective gear like safety masks and glasses. If brake cleaner comes into contact with your skin, wash the affected area thoroughly.
In addition to damaging plastic and skin, brake cleaner is also harmful to other materials. For example, it is not recommended to use brake cleaner on metal parts that will be welded, as it may create toxic fumes. Similarly, chlorinated brake cleaners, which were more commonly used in the past, are now banned in some places due to the ozone-depleting properties of their ingredients.

Non-chlorinated brake cleaner is safer to use on plastic
Brake cleaner is a product used to clean brake parts, including rotors, drums, calipers, cylinders, springs, and other related parts. It is designed to remove contaminants such as grease, brake dust, fluid, and oils that can accumulate over time and cause premature wear and lower brake performance.
There are two main types of brake cleaners available on the market: chlorinated and non-chlorinated. While both types are effective at cleaning brake parts, there are some key differences between them. Chlorinated brake cleaner is made of chlorinated solvents such as perchloro-ethylene (also known as tetrachloroethylene) and methylene chloride. These solvents are non-flammable and fast-drying, making them ideal for cleaning brake parts. However, they can create toxic fumes when heated and are not recommended for use on plastic or rubber surfaces, as they can react with these materials and cause damage.
Non-chlorinated brake cleaner, on the other hand, does not contain chlorinated solvents in its molecular structure. This type of brake cleaner is generally safer to use on plastic and rubber surfaces, as it does not have the same reactive properties as chlorinated brake cleaner. However, it is important to note that non-chlorinated brake cleaners are still flammable and should be used with caution. They may also contain alternative chemicals that are just as toxic, if not more so, than those found in chlorinated brake cleaners.
When choosing a brake cleaner, it is important to consider the type of surface you will be cleaning and the specific requirements of your project. If you plan to clean plastic or rubber parts, a non-chlorinated brake cleaner is generally a safer option. However, it is always recommended to test the product on a small area first and to follow the manufacturer's instructions and safety guidelines. Additionally, some brake cleaners may not be compliant in all areas, so it is important to check the regulations in your state or region before purchasing.
Overall, while non-chlorinated brake cleaner may be a safer option for cleaning plastic and rubber surfaces, it is important to exercise caution and follow the appropriate safety measures when using any type of chemical cleaner.
