Silicone cannot be removed with solvent. It can only be removed by mechanical means. Perhaps one of the ingredients is not silicone but something similar. Then you may have half a chance.
I'm no chemist, but I can manage to remove enough of a silcone treatment with a strong detergent solution (say 1 part detergent to two parts hot water) and a nylon brush (like a fingernail brush) to make all the difference. I think Kestas is thinking of paintwork prep where anything will leave traces of silicone, enough to stop paint adhering.
