Has anyone used CLR on a padlock that says to use graphite only? CLR is calcium, lime, rust remover.
Re: CLR on graphite only
Errrm... so why would you want to lubricate the padlock with CLR?
Re: CLR on graphite only
Not for lubricating purposes but for cleaning any rust it may have, wanted to know if it would damage padlocks that says use graphite only. Since oil can't be used on these locks wanted to know if CLR would cause any type of damage.
Re: CLR on graphite only
No, CLR won't cause any damage to the lock body.
Regarding graphite, the lock may have been lubricated with graphite by the manufacturer.

Re: CLR on graphite only
Someone tried it and the brass turned a reddish pink color which I found strange. So I searched for why that would happen and found this. "If you leave anything in it too long, it will take on a reddish color where the zinc is being removed. Any acid used to clean brass will do just that." So I suggest to test it on a small area where it doesn't show the most to see what it does and only leave it a very short time just a minute or so. I only tried it having nothing else one time it worked really well and have used it many times since but now fear the pink monster may arrive. Use with caution and some kind of safety glasses.

Re: CLR on graphite only
A picture of the specific lock in question would be better. Using CLR on brass is not recommended.

It would seem logical that the pink is copper.
