I have been having a problem with the key sliding into the door lock on my
DoKa.  Now, my dad was a confirmed Graphite man, swore by and at it all his
life.  After rummaging about in the legacy junk pile some might call
treasure (but not anyone I know), I found a bulbous rubber squirter with a
thin needle like end.  It still had some heft to it, so I knew it was not
empty.  In defiance of all my years of experience, I inserted the end of
this tool and squirted what turned out to be a pink powdery substance into
my lock.
So, my question is, “What is this pink powder, and am I in trouble?”

The powder seems sort-of slippery.
