WD-40 freezing point

You should not use WD40 on your door locks. It flushes out the dry lubricant used in locks. Ask any locksmith. Most of those lock deicers are bad as well, they do the same thing. I guess WD40 would be better than the deicers because it has its own lube. Use graphite or Molybdenum based powder lubes and you will not have frozen locks to begin with.

Take apart many locks? Most are dry lubed with graphite base or molybased lubes. Some are wet with moly or lithium based greases. The lube in WD40 is insufficient for locks. It is like you said a Water Dispersant and penetrant. It also contains solvents that will flush out any lube the lock may have had. Graphite only cakes when you use too much or when applied to a lock that is greased. Molybdenum Disulphide cakes even less.
Too many people think WD40 is a cure all. For some locksmiths it is job security. Thanks for the supportive links.

For what it is worth, a locksmith friend of mine loves WD-40. He makes lots of money from replacing lock cylinders that have been wrecked by the stuff. I would never put that crap in a lock, if I have a rusty bolt then I use WD-40. Marvel Mystery Oil, or gun lube both are much better. There is also lock oil, I don't remember the name, available.

What does your friend say that the WD-40 does to the locks?
What kind of locks? Car door locks? House Door? Other kinds of locks?

I have been using WD40 in my vehicle door locks for about 50 years, giving them a couple of shots at the start of winter. I have never had a door lock freeze up on a vehicle that has had this treatment. This is in Vancouver, Canada where we get lots of rain (moisture). I picked up this trick while working in gas stations.
