Degreaser can soften plastic
Degreasers are designed to remove grease, oils, cutting fluids, corrosion inhibitors, fingerprints, and other contaminants. They are commonly used in motor repair and engine cleaning. While degreasers are effective in breaking down tough sludge, some people are unsure whether they can be safely used on certain materials, such as plastic.
Gunk Engine Degreaser, for example, is a highly effective degreasing solution that has been proven to remove stubborn oils and gums. However, some users have reported that it leaves white spots on plastic and rubber surfaces, causing them to look unappealing. In addition, one user observed that Gunk Engine Degreaser softened the plastic on their rad/intercooler bracket.
The Gunk Engine Degreaser contains petroleum distillates, which are known to be harmful to rubber and plastic components. These distillates can cause rubber to dry out and plastic to soften, craze (create small cracks), or become brittle. Therefore, it is important to exercise caution when using degreasers on plastic surfaces and always test on a small area first.
To avoid damaging plastic surfaces, it is recommended to use alcohol- and hydrocarbon-based solvents, which are generally safer for sensitive plastics. These solvents are less likely to cause swelling, shrinking, or other permanent changes to plastic and elastomeric materials. Additionally, covering plastic components with plastic wrap or a bread bag before using a degreaser can provide extra protection.
In conclusion, degreasers can soften plastic, and it is important to carefully select a product that is safe for use on plastic surfaces. Testing on a small area first and taking precautionary measures, such as covering plastic components, can help prevent damage.

Degreaser can be used on electrical connectors
Degreasers are cleaning agents designed to remove grease, oils, cutting fluids, corrosion inhibitors, handling soils, fingerprints, and other contaminants. They are commonly used in metal fabrication, motor repair, and airplane hangars.
When using a degreaser, it is important to consider the material you are working with and the type of degreaser being used. For example, if you plan to work on electrical connectors, it is crucial to use a degreaser with a high dielectric strength, which is the maximum electric field that the material can withstand before its insulating properties break down. Using a degreaser with a low dielectric strength on electrical connectors can lead to a breakdown of the insulating properties, allowing electricity to flow through and potentially causing a short circuit.
Additionally, care must be taken when cleaning plastic components. If the degreaser is incompatible with the plastic, it can cause crazing (creating small cracks), embrittlement, or softening of the material. In the case of GUNK Engine Degreaser, a popular product, users have reported that it left white spots on plastic and rubber surfaces, softened plastic, and removed paint. However, others have used it for years without any issues, and the manufacturer claims it is safe for plastics, rubber, and paint.
To avoid potential issues, it is recommended to cover sensitive components, such as the battery, alternator, and air filter, with plastic wrap before spraying the degreaser. It is also important to disconnect the battery before cleaning to prevent any electrical issues.
Some alternatives to degreasers for cleaning electrical connectors include Electronic Parts Cleaner, MAF Cleaner, 99% isopropyl alcohol, and dielectric grease. These products are designed specifically for cleaning electrical components and are less likely to cause damage. Additionally, products like WD-40 can be used as a lubricant and protectant to prevent corrosion and make it easier to disconnect connectors in the future.
In summary, degreasers can be used on electrical connectors, but it is important to select a product with a high dielectric strength and to take precautions to avoid damage to plastic and rubber components. It is always recommended to refer to the manufacturer's instructions and safety data sheets before using any chemical product.
