In a nutshell, it works exceptionally well and lives up to its advertised claims.
Superzilla was sprayed on the door hinges on the cab of two Ram 3500 pickups. These hinges were squeaking badly, especially in damp climates. Superzilla shut down the squeaking in seconds, something none of the other products we used in the past could do.
I purchased a 10.14-ounce aerosol can of Superzilla on Amazon. It sells for $13.95, but by the time tax and shipping were added, it was almost $22, which is expensive for this type of product. That said, by the time RV Enthusiast Technical Director Bill Gehr and I were done testing, we concurred that it was worth every penny.
As a cleaner, Superzilla is touted to remove “virtually anything that soap and water won’t clean” so we wrote Bill’s name on a plastic telescoping stool with a permanent marker, which is just about impossible to remove. This stuff took the letters right off the plastic with almost no effort.
Next, we sprayed Superzilla in the entry and compartment door locks — and they loosened up nicely. A natural capillary action allows the plant-based liquid to travel up to the tumblers and provide the necessary lubrication to break up any restrictions due to corrosion and other debris. That aspect worked beautifully, but didn’t work as well as silicone paste on the bolt and striker plate since the liquid dripped off the surface. However, it did provide enough lubrication to keep the latch from binding.
To test another claim — that the oil can travel uphill — we compared the action of Superzilla sprayed on a seized, rusted nut-and-bolt with WD-40. Sure enough, the Superzilla wicked uphill better, providing a much deeper penetration of oil; the nut was then able to be moved by hand. Pretty impressive.
If you read the entire promotional flyer that comes with the Superzilla, you’ll learn that the lubrication properties are claimed to be “more slippery than oil.” Again, that’s a tall order for any product, so we also tested that claim, which states that the oil leaves a non-ionic charge to prevent the attraction of dirt and dust. We both have Ram trucks with the same squeaky hinges on the front doors. We’ve thrown everything we had at those annoying hinges over time, and nothing worked. A couple of squirts of Superzilla silenced the noise on both trucks within a few seconds — and the squeak hasn’t returned after more than a month.
While the aerosol can at first blush seemed like the most versatile method of deploying Superzilla, we did find that the spray pattern is a little hard to control without the use of the straw that attaches to the nozzle. If storage space is limited, you can opt for an 8-ounce pump spray bottle ($22.95); it also comes in a 1-liter bottle with a trigger sprayer ($33.95) and even a 1.9-ounce, pocket size pump-spray bottle ($6.95). The spray bottles can also be refilled from a 1-gallon can that sells for $109.
Superzilla is made in the U.S.A. and, if you’re like us, you’ll be pleasantly flummoxed — what seems like advertising hoopla will have you scratching your head trying to figure out how a non-hazardous, non-corrosive and non-flammable liquid made from plants can do all this.
