Diluted Cholorplatinic acid (H2PtCl6), if coated or sputtered on any substrate, can be stored in a desiccator for months, rightly said by Nikhil. But if you have activated your Pt film at high temperature (as we do at 400 C for 20-30 min) then its sensitive to reduction/oxidation and you better use it in hours.
