The electrodes is always make contact with different chemicals, and some electron transfer processes always leading to some decomposition of the substrates. The decomposed polar materials are easy to adsorb on the elctrode surface. also in some cases it will effect the surface properties of electrode. It may cause in unexpected peaks or over current problems. So it is better to clean the surface after the experiment
In the case fresh electrode it is better to clean before use since the surface may contain some unfixed electrode materials, which may come in to solution when we dip to sultion, Or in case of film making, it will effect the perfection of adsorption. Once we clean by sandpaper the surface will more reliable for the experiment

Difference between reference electrode and indicator electrode?
Often electrochemical studies are interested in one of the electrodes of the cell only. The second electrode is present to complete the cell. Electrode of interest is named working electrode or the indicator electrode; the second electrode is know as reference electrode or auxiliary electrode (counter electrode).
What are the Types of ion selective electrodes?
glass electrode, antimony electrode, the hydrogen electrode
What type of electrodes use in pH meter?
Examples: glass electrode, combined electrode, platinum electrode
What type of electrodes are used in potentiometric titration?
Potentiometric titration is a method to detect potential difference between the indicator electrode and reference electrode and thus determine concentration of chemical component, which reacts with reagent added to a solution potentially in equilibrium at the beginning.The popularly used reference electrode is either silver-silver chloride or mercury sulfate electrode, and the indicator electrode is generally made of glass electrode, platinum electrode and silver electrode or ion selective electrode.
What is the difference between mono polar and bipolar electrode?
Monopolar electrode is single electrode measure voltage with respect to grond ,but bipolar electrode is two electrode measures the diff. voltage mainly bipolar is used inorder to get high Signal to Noise ratio.
How do you clean grease pencil from raw wood?
Sandpaper.
Will wet dry sandpaper clean yellow from gunite pool?
NO.
How do you clean an untreated softwood floor?
You need a fine grit sandpaper to clean untreated softwood floor. Use the fine grit sandpaper to gently clean the wooden surface as the dust is wiped away. This procedure should be repeated until the stain is no more.
Is the metal frame of a house an approved grounding electrode?
No, but the frame of a metal house must be grounded to an approved grounding electrode.
How do you clean a contact pad on power sliding door on Oldsmobile silhouette?
Clean corrosion off contacts with fine steel woll, sandpaper, etc.
How do you clean copper used in plumbing?
Sandpaper, emery cloth or wire brushes sized for the different sizes.
What a disadvantages to using a hydrogen electrode?
The electrodes must be kept dry.
Within how many feet must the welding cable be spliced from the electrode holder?
A minimum distance of 10 feet from the cable end to which the electrode holder is.
Why does Sandpaper have high coefficients of friction.?
It is very rough. But please note that "coefficient of friction" isn't specified for a single substance. Rather, it is specified for the COMBINATION of two different surfaces. It must also be specified if some lubricant is used. For example sandpaper on sandpaper, sandpaper on glass, glass on glass (dry), glass on glass (wet), etc.

Try rubbing it away with fine sandpaper. Or alternatively immere the iPOD overnight in vinegar.
How do you clean 1998 Chevy silverado headlight lens?
I used 800, 1000, 2000 sandpaper then buffed with rubbing compound.
