Presently, both brands secure formulas, but it is clear that WD40 primarily features petroleum-based oils, while its counterpart has plant-derived oils.

We will look at more contrast points of the two based on the following facets.


WD40 was initially a water-displacing spray, which evolved to perform numerous industrial and household roles. Superzilla came into the scene as a cleaning, lubricating, and penetrating agent.

Many people lean towards Superzilla for its superb cleaning and lubricating capability. WD40 has a large and loyal following that appreciates its vast adaptability, evident from its over 2000 uses.

On application, both brands are flexible and can handle several tasks, though Superzilla focuses on some specialty areas, like cleaning and lubrication.

Can Superzilla Be Used on Guns?

Superzilla’s superior cleaning, lubricating, and penetrating qualities may tempt you to use it on your gun. You should not use Superzilla on firearms, as it has a high penetrating power and could reach the primer or wear out the bluing, affecting their performance.

Instead of Superzilla, you can use Gunzilla, also from TopDuck Products LLC. Gunzilla is a safe product that will improve your gun’s service.

Is It Bad to Oil a Gun with WD40?

Oiling is a crucial gun maintenance practice that reduces friction between moving parts, translating to better performance. While WD40 has great lubricating properties, you should not use it to oil your gun.

First, the spraying action when using WD40 may push gunk in the gun deeper into unreachable crevices. WD40 evaporates faster than regular gun oil, rendering it useless as a lubricant. Always use the right gun oil to clean and lube your gun to have it in the best shape.

What Does WD Stand for In the Product WD-40?

WD in WD-40 stands for water displacement and is a significant part of this brand. Back in 1953, three Rocket Chemical Company staff members were out to develop a line of rust-prevention solvents for aerospace use.

Will Superzilla Or WD-40 Harm Rubber?

You should ensure that penetrating oil is compatible with a material before using it to prevent damage. WD40 is not entirely safe on rubber. You should use WD40 sparingly on rubber, as prolonged use will wear it off. WD40 will dissolve the oils in rubber, making it brittle.

On the other hand, Superzilla is safe on rubber, though you must be careful when using it to avoid wearing away the material. Wipe off excess fluid from the rubber and avoid soaking it, as the fluid may eat it away.

Which Is Better, WD40 Or Superzilla?
