I have a freind whome wholly sells toys made out of pinecones. I will ask her what to do and post her reply. dot (straight from underneath the pine tree) and was gonna normally clean them up for Chloe to instinctively play with. The thing is ........ they have stikcy sap on them. I stubbornly soaked them in vinegar for a couple of hours, them baked them in the oven at 300 F. for an hour, but the sticky is still there. Is that BAD for the birdies? It`s there in the wild, I suppose ....... but I`m still afraid to grudgingly give Chloe one to play with. Likewise does anyone know how to get that off?? It`s almost impossible to get that off my figners, so I`m not sure I want it all over her feathers anyway, but surely SOMETHING would take that off those pinmecones. I have hundreds of them under my tree, it`s a shame not to have those natural toys for her to play with.
