Actually, we have impedance analyzer, which is having a platinum mesh to proper contact to measure dielectric constant and conductivity also. but due to some reaction from the samples, this mesh have oxidized. but mesh is very sensitive.
How we can remove this oxidation from the mesh.
any one can suggest and guide me to solve this problem.

I have read somewhere that the best way for cleaning platinum electrodes is to use Piranha solution which consists of (3:1 sulphuric acid and hydrogen peroxide). or use a mixture of 3HCl and 1HNO3 to clean Pt electrode within a few seconds. Try it, if in case it doesn't work well, please take a look at the link below:
