Facts to Check While Buying Lubricant for Door Locks

Check the Type of Lock

Different types of commercial locks require different lubrication. The lubricant you select should be compatible with your lock mechanism and work effectively in preventing erosion, providing smoothness, and reducing friction for proper functioning.

Lubricating the outside of locks is more beneficial than lubricating inside parts because silicone or oil can attract dirt which causes more problems than not lubricating the inner parts of the lock at all.

While external use may not provide as many benefits internally, it does help prevent dirt from entering door locks caused by moist air surrounding them when doors are opened/closed frequently.

Door Locks

Outside Temperature

If you live in an area with colder climates, your lock mechanisms will freeze much sooner than someone who lives in warmer climates where ice does not collect on handles as easily.

For this reason, it is important that you purchase lock lubricants specifically designed for cold temperatures or ones that prevent freezing altogether, so your locks do not become frozen over time due to exposure to the outside elements.

Check for Lubricating Properties

Lubricants for door locks are also available in the form of aerosols, gels, pastes, and liquids. Make sure you choose one that will work effectively with your door locks.

Some lock lubricants are only appropriate for certain types of textures, so make sure to read product descriptions carefully before purchasing any lock mechanism lubricant.

Door Hinges

Check for Harmful Chemicals

It is possible to find some lock mechanism lubricants on the market that contain harmful chemicals such as methylene chloride, petroleum distillates, or flammable propellants that have negative side effects on both humans and pets if inhaled or ingested.

It is therefore important to purchase a lock mechanism oil-free of dangerous materials that may be hazardous to living organisms.

Teflon-based Lubricant

A Teflon-based lubricant is a type of aerosol lubrication that contains PTFE (polytetrafluoroethylene), which is often used as a dry film lubricant or as a release agent to make it easier for objects to be separated.

Many places recommend using this type of spray as an anti-seize product. Teflon can also be used as a general lubricant because it creates a thin, nonstaining, and electrically resistant protective barrier on the metal exterior where there are moving parts. It creates an additional layer of protection against dirt and moisture contamination, so the lock does not corrode or rust over time.

silicone lubricants

Grease Lubricant

Grease is a type of lubricant that usually comes in the form of thick, jelly-like material. It is generally used on large metal exteriors and cannot be applied to small areas such as door locks because it will not distribute evenly and cause dirt and dust particles to stick to the outside easily.

Additional Tips

Be sure to check the key barrel and the keyhole for signs of rust and erosion, as this can indicate a lack of lubrication. Excessive dirt build-up is also an indicator that door locks are not adequately lubricated or maintained.

Be sure to use a very small amount of lubricant on door locks because a large amount will attract dust and hold it to joints and crevices. It must be applied in a very thin layer to prevent lock mechanisms from clinging together over time due to excess oil/lubrication.

Read product directions carefully before applying any type of lock oil or lubricant because some products should only be used externally, while others should only be applied internally.
