These lubricants can be used for many other purposes than door locks. Many of these lubricants can be used to work with machine parts, motor vehicles and conveyor belts. So without further ado, let’s help you to get unstuck with these best lubricants for door locks.

How to Choose the Best Lubricant For Door Locks
You can’t go wrong with any of these, especially since these are the best of the best. They all work together to lubricate door locks that are stuck.
However, you’re always trading one aspect for the other, and you may want a good all-around lubricant or one that will not stain the carpet.
Cleanliness
If you want a cleaner lubricant, such as the 3M, you may be giving up the effectiveness to keep off dust and dirt, but if you are more interested in long-lasting protection such as with the B’laster, you may have to deal with more of a mess.
The most environmentally-friendly lubricants seem to be the best, as they require a more precise application.
For example, UniSport and Leafy Lock have bottles that are more precise and, because they are mineral-based oils, they go on clear.
Alternative Uses
With an effective lock lubricant, once the initial lubrication is finished, you probably won’t be touching that lubricant until another issue with a stuck lock arises.
We recommend you get the most value for your money and buy a lubricant that can be used for other purposes.
You might be a mechanic who works on your car occasionally and needs a lubricant that is safe for the parts. This is where we recommend the CRC Dry Graphite Lube (or the 3-IN-1 Lock Dry Lube), which can be great for motor vehicles.
However, if you like to tinker with machine parts in your garage, we would point you towards the B’laster GS or the WD-40 Specialist.
We recommend the UniSport and Leafy locks if you are outdoors working or camping with metal, wood or plastic materials that need lubrication and corrosion prevention or rust-fighting properties.
