Why have so many people on this NG got such a downer on WD40? The solvent
carrier in WD40 could catch fire true, but its gone in a few seconds and
there is no reason why it should clog anything up - quite the opposite, it
cleans things. I've used it on all sorts of locks for years and years and
never had the slightest trouble.

IMO a wonderful product.
