Weird.  But I guess you knew that. :-)

I don't actually think there is a separate command to do this, alas
(I would've thought that route -f would take care of it as well, but
it doesn't appear to).  I just run a quick script:

# arp -d | awk '{print "arp -d " $1}' | sh

If there's an easy command to do it, I'd love to hear about it.
