blabbered, again:


That¢s not a good idea, it then attracts dirt which make the lock worse.
Powdered graphite works much better in the lock.

For a lock that the OP intends to reuse I might agree with you. In this
case it is probably rust or other oxide that is preventing the lock from
opening.

I found it was actually the pins not moving freely in the padlock I use

Nobody was talking about your padlock, senile Ozzie cretin!
