There is no spray that will penetrate well enough to do the job. You need to use silicone or teflon grease only. Nothing else will work. You have to disassemble everything, clean off whatever lube you uses, and then apply the correct grease to any surface where poly meets metal. It's a lot of work, but that's really all you can do.
