I don't use any of the typical loosening penetrating oils. I have had
nothing but sucess usiing the dye penetrant spray typically sold at
welding supply stores for checking for cracks and cold welds..... Used
it on highly rusted stuff to items that were in a slat environment,
and lots of other problematic frozen things and its never failed me.
