Is it possible to remove old silicone sealer where interior window frames meet double glazed uPVC window units? I'd like to be able to remove the stuff that's on there at the minute and replace it with the same or something better.

And I this tool is handy for getting into the corners. http://www.screwfix.com/p/unibond-sealant-smoother-remover-tool/99849
