FAQ's

Is WD-40 a degreaser?

WD-40 is a lubricant (fish oil to be exact) dissolved in a solvent. While it can break down grease and oil to a certain degree, it also adds back some. This might be desirable if you are cleaning a hinge, conveyor, or corrosive-prone part, but not if you need it truly clean. For example, if prepping a surface before painting, cleaning with a cleaner/lubricant will lead to the paint dewetting (beading) or delaminating (flaking off). Chemtronics offers DPL for lubrication, and degreasers under the Eletro-Wash and Max-Kleen brands for high precision cleaning.

What is the best degreaser?

That depends on the requirements of your application. There are a number of factors that can have a big impact on performance and safety: flammability, dielectric strength, compatibility, toxicity, and environmental impact. Degreasers often contain very flammable alcohols and hydrocarbon solvents. They can be cheap and effective, but can dangerous without proper ventilation, or around open flames, sparks (e.g. welding), or hot surfaces. Nonflammable degreasers avoid these safety issues, but are generally more expensive. If you plan to powered equipment, or need to switch it on before the solvent has flashed off, consider a degreaser with a high dielectric strength.  More care needs to be taken when cleaning plastic packaging, plastic components, rubber gaskets and seals. If the degreaser is incompatible with the plastic, it can craze (create small cracks), embrittle, or soften the material. Rubber seals may swell, shrink, or dissolve if exposed to a harsh solvent. A new degreaser should always be tested before being used extensively. N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher. Volatile organic compounds (VOCs), solvents that add to smog, or solvents with high global warming potential (GWP) have been a focus of a number of regulators. Some state (e.g. CARB or California Air Review Board), municipal, and even industry-specific regulations restrict the use of high VOC or high GWP materials.

Should I use gloves when using a degreaser?

Yes, it is a good idea to use gloves when degreasing. The solvents used in degreasers do a great job at breaking down greases and oils, which also happen to exist in health skin. If your hands are exposed to a degreasing solvent for enough time, oils will be drawn from your skin leading to “defattening”. Your skin will become very dry and you could eventually develop dermatitis, which looks more like a rash. In addition, some solvents like N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic, so can be absorbed through the skin and cause issues like cancer, or impact liver or kidney function. Please wear gloves and other PPE as required.

Are degreasers toxic?

There are no degreasers that should be taken internally, but some ingredients are more harmful than others. N-Propyl Bromide (nPB), Trichloroethylene (TCE) and Perchloroethylene (Perc) are highly toxic chemicals commonly used in degreasers to provide cleaning performance in a nonflammable formula. There are documented court cases where workers suffered major health effects when exposed to high levels of these chemicals. Workers reported headaches, dizziness, and even loss of full body control. There are also possible links to reproductive problems and cancer. All of this has caused maintenance facilities to reconsider their solvent choices, especially with manual cleaning when exposure tends to be higher.

Do I need to shut off power before cleaning electrical equipment?

Before you start spraying, shut down power to avoid the potential of sparks, electrical shorts or discharges, and other safety hazards. If disconnecting the power is not an option, look for degreasers with a dielectric strength above 30 kV (30,000 volts). Choosing a nonflammable cleaner would also add a layer of safety in case there is a spark.

What is degreaser used for?

A degreaser is a cleaner designed to remove grease, oils, cutting fluids, corrosion inhibitors, handling soils, finger prints, and other contamination common in assembly, stamping, other types of metal fabrication, refineries, motor repair, airplane hangars, and many other applications. Degreasers go by a number of different names, including precision cleaner, maintenance cleaner, and specific for automotive repair, carb cleaner, brake cleaner. The objective for a degreaser is to remove the offending soil quickly, avoiding as much wiping and scrubbing as possible.
