Cleaning Conditions
After soldering use cleaning solvents such as chlorosen, dyefreon, suitable aqueous or
semi aqueous cleaner.
Storage
To prevent damage to the electrode, be sure to observe the following cautions for storage.
Store in 40C maximum ambient temperature, and 70% maximum R.H.
For maximum possible shelf life do not disturb polythene sleeve until you are ready to use.
Store where there are no harmful gases containing sulphur or chlorine.
