What To Look For In an Electrical Contact Cleaner


When it’s about finding an electrical contact cleaner, you must consider your job requirements and other crucial facts. There’re so many options available for the best electronic contact cleaner. You should buy one that meets your demands and protects connections from dust.

Below we’ve mentioned some crucial factors that you must evaluate if you don’t want to end up getting an inferior one.


It might be possible that the contact surfaces are made out of rubber, plastic, or any other metal. Before applying the contact cleaner, it would be preferable to test those cleaners on such surfaces to see any side effects.

Getting a lousy contact cleaner can dissolve, shrink, or damage the rubber or plastic seal. That means you must figure out this point before settling yourself on a specific contact cleaner.

Environmental Facts

Since electrical contact cleaner is applied as a spray, there’re many possibilities of creating serious environmental issues.

If you use an inferior cleaner, sometimes this can lead to the depletion of the ozone layers. It’s good to avoid those contact cleaners that contain high GWP or VOC materials in ingredients.

Low Kb value

Most times, the best contact cleaner is applied to ensure cleanliness. It can provide excellent results and remove dirt quickly. However, if you plan to clean an electronic surface made of various components, it’s better to use a cleaner with a low Kauri Butanol value (Kb value).

A strong cleaner might graze, dissolve, or damage the softer substrate. In that case, a mild and plastic-safe contact cleaner is preferable. The best electronic cleanser with a 15-40 Kb value is gentle and entirely safe for all surfaces. You can check out the Kb value on the contact cleaner’s specification datasheet.


A contact cleaner is meant to improve the conductivity of your electronic devices. Toxic ingredients in specific cleansers include perchloroethylene and propyl bromide. For these harmful compounds, workers face severe health problems like body pain, headache, loss of control.

Non-toxic and non-flammable are the top qualities to look for in an electrical contact cleaner. Before purchasing your preferred electronic contact cleaner, consider these critical factors.
