5 Little Known WD-40 Products Worth Having Around The House

WD-40 Isn’t Just One Product, But a Full Line of Useful Products Worth Having On Hand

WD-40 Spray

Probably every household has a yellow and blue can of WD-40. This well-known multi-use product solves so many issues that it is nearly synonymous with the brand. In fact, you might not even know that WD-40 puts out a variety of other lubricants and products that also deserve a place on your garage shelf.

A Little WD-40 History

WD-40 Spray Can

WD-40 was originally developed by a company helping the aerospace industry create the Atlas rocket. The engineers needed a chemical to prevent rust and corrosion during the rocket manufacturing process. As it turns out, the 40th version of the water displacement formula was perfect — hence the name WD-40.

One day, when management noticed that some employees were taking home small vials of the formula for personal use, they realized they had something that wasn’t just for rocket science. In 1958, they produced an aerosol version in San Diego, California to sell to the public, and the business took off like, well, a rocket!

The WD-40 Specialist Line

In 1969, the multi-purpose product was the only product in the WD-40 line-up, but the company put their knowledge and expertise to use and over the years developed new products including the Specialist Line for the trade pros. In 2020, they repackaged the WD-40 Specialist lineup with the iconic blue and yellow cans with the red cap.

WD-40 Specialist Brand Manager, Stepan Harmanlikian noted that the Specialist Line is “an underappreciated WD-40 brand offering since some professionals are unaware of the product line.” The Specialist Line has several offerings that the home garage mechanic or automotive hobbyist can certainly appreciate and use.

WD-40 Specialist Contact Cleaner

WD40 Specialist Electrical Contact Cleaner


In our connected world, with more specialized electronic gear and gadgetry than ever, electrical contacts are often exposed to condensation or corrosion, especially in cars. The WD-40 Electrical Contact Cleaner Spray rids sensitive electrical components of corrosion and leaves a protective layer. According to Harmanlikian, “It is safe and ideal for use on printed circuit boards, controls, battery terminals, switches, precision instruments, and electric panels.”

WD-40 Specialist Silicone

WD-40 Silicone Spray


One of my favorite lesser-known WD-40 products is the company’s silicone spray. It is a great lubricant and protectant for vinyl and rubber. It drys clear and doesn’t seem to attract dirt or leave a residue so it is great for use on a car’s weather stripping. It also protects against rust and acts as a water barrier.

WD-40 Specialist Bike Chain Lube

WD-40 Bike Chain Lubricant


As a kid, I liberally sprayed my bike chain with the WD-40 Multi-Use Protectant, but the WD-40 Specialist Bike Chain Lube is a much better product. It protects in both wet and dry climates while eliminating squeaks. Consistent use will prolong the bike chain’s life by offering corrosion protection without using wax, which attracts dirt and other contaminants.

WD-40 Specialist Corrosion Inhibitor

WD-40 Corrosion Inhibitor


This product helps protect metal parts from rust and corrosion for up to 2-years of effective use indoors or 1-year outdoors. This anti-rust spray stays where you spray it and is ideal for preventative maintenance. If you live in a high humidity area this is a must-have product.

WD-40 Specialist Gel Lube

WD-40 Gel Lube


Harmanlikian’s personal favorite (and another under-appreciated product) is the Gel Lube. It prevents rust for up to 1-year with its long-lasting lubrication. Since it is a gel, it can be used on vertical surfaces, and it won’t fling off moving parts. You’ll love its ability to stay put, giving you added longevity and protection.

Cover Your Bases With These WD-40 Products And More

The WD-40 lineup includes over 35-items, including different sizes. You can even purchase a massive 55-gallon drum of the WD-40 cleaner and degreaser.

The WD-40 Multi-Use Product has over 2,000 official uses according to the company. Our guess is WD-40 is not done yet, and will have even more new useful products for consumers and professionals alike in the years to come.
