GroLine Cleaning Solutions 

GroLine Cleaning Solution is a specially formulated acid that cleans pH electrodes.  Growers should avoid touching the glass on pH electrodes as doing so can damage the electrode's invisible (but extremely important) gel layer.  Toothbrushes are NOT good for pH electrodes, rather than damage the electrode with physical handling it is best to soak them in cleaning solution.  

To use: place the pH electrode into cleaning solution and allow it to soak for 15 minutes.  Cleaning solution is an acid and acid dehydrates the gel layer while it cleans off unwanted deposits. After using cleaning solution the electrode must be soaked in storage solution for several hours to rehydrate its gel layer.
