A general purpose cleaning solution that can be used for a variety of applications.
 
Electrodes can become dirty from use and will produce inaccurate results even as they read correctly in a pH buffer. This cleaning solution eliminates impurities and residues that are left on electrode surfaces when immersed in samples during measurement or when stored incorrectly. 
 
Cleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. Simply immersing the electrode in the cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.
