I would suggest to dissolve the poly(vinyl butyral) coating over the Pd foil with glacial acetic acid at room temperature and/or with other suitable organic solvent such as n-butanol, dioxane, ethyl glycol ether, ethylene chloride or tetrahydrofuran.

prof V.S Muralidharan

try cathodic cleaning in acetic acid

Frank Kern

if the PVB (polyvinylbutyrale) was a solution in ethanol before it is probably the best to use ethanol or another aliphatic alcohol to dissolve the layer again. Probably you have to was several times to get rid of it entirely.
