How to deal with sticking mailbox locks

How to deal with sticking mailbox locks

While the locks on Mail Boss mailboxes are designed to endure outdoor environments, there are occasions when a lock may stick or seize. In many cases, this is a totally reversable process through lubrication of the lock.

 

What lubricant should I use on my mailbox?

Many customers have WD-40 on hand, and opt to use it on their sticking locks, but this isn't our first choice. The military developed WD-40 in the 1950s to be used as a water displacing substance in order to keep mechanical parts from rusting. It is a petroleum based product. As time went on, people discovered that it is also good for loosening parts that are stuck, and as a general household lubricant.

Then came Tri-Flow, which is a lighter petroleum based lubricant with microscopic particles of Teflon in it. There is a huge debate over the uses of each product and which one is a better lubricant.

 

WD40 vs. Triflow

I have been using both for decades for different purposes. I find that WD-40 works best for loosening rusted or seized parts on cars and other equipment. But after I use it, I am sure to get it all off, because dirt has a tendency to stick to it.

For door hinges, locks and other outdoor uses, I think Tri-Flow is far superior. I find that Tri-Flow stays around longer and keeps these things working better for longer. I also have found that Tri-Flow does not attract dirt and debris as much as WD-40.

Most people don’t realize they need to lubricate their locks at least biannually. Regular monitoring and maintenance of your mailbox is the best way to keep it in prime condition for years to come.
