2. Brake cleaner - Wikipedia

   en.wikipedia.org/wiki/Brake_cleaner

   Non-chlorinated brake cleaners use hydrocarbons as a main component; it will either be a low-boiling aliphatic compound or higher-boiling hydrocarbon mixture. Aromatics like benzene, toluene or xylene may also be used. [6] The hydrocarbons used are sometimes made by hydrogenation from naphtha. The lipophilic liquids dissolve fat-soluble ...

   CRC's first product, 5-56, is still sold. However, 6-56, a silicone-based replacement, is CRC's current competing product for WD-40. [5] Brakleen, a tetrachloroethylene (PERC)-based brake cleaner, is one of CRC's signature products. It has gained a cult following due to its dissolving power and has been used off-label for many other purposes, a ...

4. Tetrachloroethylene - Wikipedia

   en.wikipedia.org/wiki/Tetrachloroethylene

   It is a non-flammable, stable, colorless and heavy liquid widely used for dry cleaning of fabrics. It also has its uses as an effective automotive brake cleaner. It has a mildly sweet, sharp odor, detectable by most people at a concentration of 50 ppm. [6]

5. Parts cleaning - Wikipedia

   en.wikipedia.org/wiki/Parts_cleaning

   For liquid media, the following cleaners can be used: aqueous agents, semi-aqueous agents (an emulsion of solvents and water), hydrocarbon-based solvents, and halogenated solvents. Usually, the latter are referred to as chlorinated agents, but brominated and fluorinated substances can be used.

6. Trichloroethylene - Wikipedia

   First, ethylene is chlorinated over a ferric chloride catalyst to produce 1,2-dichloroethane: CH 2 =CH 2 + Cl 2 → ClCH 2 CH 2 Cl. When heated to around 400 °C with additional chlorine, 1,2-dichloroethane is converted to trichloroethylene: ClCH 2 CH 2 Cl + 2 Cl 2 → ClCH=CCl 2 + 3 HCl. This reaction can be catalyzed by a variety of substances.

7. Cosmoline - Wikipedia

   en.wikipedia.org/wiki/Cosmoline

   Cosmoline is also frequently applied to automotive disc brake rotors at the factory, to prevent corrosion inside the box before the rotor is placed into service on a vehicle. It is easily removed by spraying brake cleaner on the braking surfaces of the rotor although brake pad manufacturers do not recommend this technique.
