When my neighbor lent me his meat slicer he said if it sticks to squirt cooking spray onto the track, that is what he did. Well it was sticky, but the track was all gummy, I'm assuming from that cooking spray and anything else that might stick to the spray. I ended up cleaning it for him and it worked fine. Just sayin', I like the idea of a food safe non-stick spray, but I don't think it works as well on mechanical devices as is does a muffin pan.
Of course, I would rather taste butter flavored Pam in my canned tomatoes than WD-40
