Okay, maybe that’s an exaggerated title, but Superzilla is a cleaner, lubricant and penetrating oil all wrapped up in a single dispenser that seems too good to be true — until you try it.
If you’re an RV owner, you likely have an arsenal of cleaners, lubrication products and even penetrating oil for stubborn fasteners and other every-day purposes. I typically rely on dry lubricants and silicone-based sprays/paste for a number of projects. So, when I saw a commercial on TV for Superzilla — a spray product that “does it all while being environmentally friendly” — I had to try it. The company, TopDuck Products, calls this stuff “The Green Wonder Product” and makes some “wild” claims about how well it works.

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.

As a penetrating oil, Superzilla promoted itself as the “best in the world.” We tested the claim that the natural capillary action would travel uphill and work its way through a rusted nut — which it did with flying colors. We tested it against WD-40, which eventually broke the rusted nut loose, but much of the oil ran down as opposed to the Superzilla moving up and covering more of the threads.

Since the product also touted its cleaning action — including being capable of removing permanent-marker ink — we tested that claim by first writing Technical Director Bill Gehr’s name on a plastic telescoping stool.

Cleaning ink from the permanent marker with alcohol resulted in lightening of the letters, but they did not come off.

After spraying the letters with Superzilla, the permanent-marker ink came right off with little effort. The company behind Superzilla, TopDuck Products in St. Johns, Michigan, claims that the solution will “remove virtually anything that soap and water won’t clean.” Conversely, the solution can be cleaned off with soap and water.
Superzilla is sprayed into the keyhole of an outdoor lock
We sprayed the Superzilla into a lock that was exposed to the outdoors all year. It was caked with corrosion and debris, which made inserting and turning the key difficult. After spraying inside the keyhole, the key went in smoothly and turned with no resistance. The capillary action allows the tumblers to be lubricated fully.

Spraying the exterior compartment latch with Superzilla resulted in decent lubrication, but not as good as a silicone paste, which does not run off the bolt and striker plate. We were still able to latch the door without lifting the handles.

All the keyholes in the compartment slam latches and the entry door lock were sprayed with Superzilla, which made using the keys effortless. Again, the upward action of the product is a key feature.

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.
