Customer ServiceSoldered capacitors may be cleaned using appropriate cleansing agents. While high temperatures and cleaning agent vapours accelerate the purifying process, they also contribute to the destruction of capacitor construction materials. Organic non-polar solvents like hexane, pentane, and cyclohexane can be safely used as cleaning solvents.
Customer ServiceSolvent proof capacitors are required when chlorinated hydrocarbons are used for cleaning. If aluminium electrolytic capacitors without the solvent-proof construction are present on the circuit board, alcohol based solvents are recommended for cleaning. In this case, solvents such as methanol, ethanol, propanol and isopropanol should be used.

Never touch the terminals of a capacitor directly with bare hands. Do not short-circuit between the capacitor terminals with anything conductive. Also, do not spill any conductive liquid such as acid or alkaline solution over a capacitor. Confirm environmental conditions where the device will be placed.
However it is advisable to dry immediately with hot air, which is best achieved at 85°C for few minutes. After having a capacitor exposed to high temperatures such as direct sunlight or heating elements, the capacitor life may be adversely affected.
Capacitors that have been stored for long time should be subjected to a voltage reforming process which will regenerate internal dielectric layers. When an escape of electrolyte has occurred, wash the affected area with hot water. Use rubber gloves to avoid skin contact.
Depending on the product type and operating conditions, the failure mode may involve in opening of the pressure relief vent. Electrically isolate the following sections of a capacitor from the negative terminal, the positive terminal and the circuit patterns.
