| |SAE - AS 8660|This specification covers one type of a nonmelting, heat stable silicone compound for use in high tension electrical connections, ignition systems and electronics equipment; for application to unpainted mating threaded or non-threaded surfaces, and as a lubricant for components fabricated from rubber. This compound is effective in the temperature range from -54°C (-65°F) to +204°C (+400°F) for extended periods and to 260°C (500°F) for short periods. This compound is identified by NATO symbol S-736((http://standards.sae.org/as8660/))| | |SAE - AS 8660|This specification covers one type of a nonmelting, heat stable silicone compound for use in high tension electrical connections, ignition systems and electronics equipment; for application to unpainted mating threaded or non-threaded surfaces, and as a lubricant for components fabricated from rubber.

| - | Be sure the chosen product leaves No Residue. Do not use WD40 as a contact cleaner (it can be conductive). Use a brush, lint-free cloth or swap on stubborn dirt. Only use enough cleaner for the contacts being cleaned. Check the product to see if surrounding material (pastic, etc.) might be damaged. | + | There are a number of readily available commercial products designed specifically as Contact Cleaners, such as from CRC, WD-40, etc. Look for the Contact Cleaner versions of these product brands, not their generic spray cleaners. These contact clearners are designed to reach in difficult places with a blast of chemical spray to clean the contact surfaces. Be sure to read the precautions & directions on the can as most make notice about their affects on plastics. You don't want to do more harm trying to clean your contacts. As with all chemicals, protect your face and eyes and hands whenever using any spray cleaner. |
