How Do I Choose a Contact Cleaner?

Electrical Contact Cleaners dissolve oils, remove dirt and other particulates and refresh electrical connectivity on relays, switches and other devices. They safely remove grit from hot motors and dust from inside electromechanical relays and keyboards. They are also effective at removing contaminants from hard-to-reach areas on electrical connectors, power supplies, junction boxes and distribution panels. The perfect contact cleaner should be nonflammable, noncorrosive, and have strong dielectric properties . Ideally, it could even be sprayed on energized electrical circuits without concern. It is also very important that the cleaning agent is safe for use on all component materials without the risk of damaging any delicate parts. Know Your Materials Although the capability of the contact cleaner is important, so is its compatibility with the parts being cleaned. When it comes to choosing the correct contact cleaner, first check for material compatibility. Does the device consist of just one type of material or is it made up of several materials with vulnerable components? Perhaps it has an LCD display made from transparent polycarbonate, contains inks, or includes rubber parts that may be damaged by aggressive solvents? If you are unsure about the materials of construction, it is important to test the contact cleaner for materials compatibility before the extensive use of the cleaner. Keep the Kb Value Low Quite often a strong contact cleaner is used to ensure cleanliness. It can deliver excellent results and clean quickly. However, if an electronic device is made from a variety of materials, and in particular includes plastic components, it is better to use a contact cleaner with a low Kauri Butanol (Kb) value . Too-strong contact cleaners may dissolve, craze or attack softer substrates; therefore, a milder plastic-safe cleaner is preferred. A contact cleaner with a Kb value of between 15-40 indicates that the contact cleaner is mild and suitable for most surfaces. Kb values can be found on the contact cleaner’s technical data sheet. Test the Cleaner To ensure the contact cleaner can be used without affecting materials you should conduct a ‘cleaning trial’ on a sacrificial or test part. Start with a mild cleaner first and progressively try stronger cleaners until the optimal cleaning result is achieved. Be sure to perform the testing in more than one area on the part to ensure it is safe for all the materials the cleaner may contact, either directly or indirectly. You can conduct your own in-house cleaning trials or MicroCare can conduct an in-lab cleaning assessment on some of your sacrificial test parts. The lab will conduct cleaning trials on your specific parts and contamination to ensure effective cleaning with the fewest risks to the parts.

How do MicroCare Contact Cleaners Interact with Plastic Components?

Our electrical contact cleaners are engineered to be compatible with most electronic-grade plastics. While they're designed to be gentle on common materials, we suggest performing a small test application first to confirm compatibility with your specific components.

What Kinds of Debris Can MicroCare Contact Cleaners Handle?

The MicroCare contact cleaner line effectively removes common electronic contaminants, including dust, grit and dirt as well as mineral oils, silicone oils, hydrocarbon based oils and fluorinated oils/grease. These formulas are developed to clean thoroughly without leaving behind any residue that could affect component performance.

Can I Safely Use MicroCare Contact Cleaners on Delicate Electronics?

The MicroCare contact cleaner formulations are specifically developed for electronics applications. Their non-conductive and non-abrasive properties make them suitable for cleaning sensitive components like circuit boards and electronic connectors while maintaining device integrity.
