Introduction to the WD-40 Experiment

When it comes to WD-40, many are familiar with its multifunctional properties—from lubricating squeaky hinges to protecting metal from rust. But have you ever wondered about the drying speed of different WD-40 products? This experiment aims to provide clarity on this topic.





Materials Used


Cardboard Testing Surface

Cardboard was chosen for this experiment due to its absorbent nature, making it ideal for demonstrating the drying speed of each WD-40 product.




I tested the following WD-40 products:

All these products are available to view on Amazon.



Methodology



Each WD-40 product was applied to a separate section of the cardboard. The amount of product applied was kept consistent across all sections. The drying time was then observed and noted for each product.

This image shows that WD-40 Contact Cleaner was by far the fastest drying. Leaving no visible residue.

One surprise was the WD-40 Original had more spread than all the others on test.





Experiment Observations


Absorption and Drying Rate

Upon spraying, each of the WD-40 variants on the cardboard, differences in absorption and drying rates were immediately noticeable...

Texture and Residue

After the drying period, an inspection of the cardboard revealed differences in texture among the four products. The residual print, especially from the WD-40 Contact Cleaner, was minimal, making it easy to see the remaining residue. This visual distinction can help users gauge the potential long-term effects of each product on a given surface...






The Potential Benefits of Residue


While in this experiment, a lesser residue is seen as beneficial for the purpose of a contact cleaner, it's important to note that some WD-40 products are designed to leave behind a residue intentionally. Here's why:



Lubrication: Products like the WD-40 Dry PTFE are formulated to leave a lubricating film. This residue can reduce friction between moving parts and extend the life of mechanisms.




Protection: Residues, especially from products like the original WD-40, can form a protective barrier against moisture, preventing rust and corrosion.




Long-term Effect: Some residues ensure that the product continues to work over a longer period, reducing the frequency of re-application.



Results

Product

Dry To Touch

WD-40 Specialist Contact Cleaner

1 minute 20 seconds

WD-40 Specialist Dry PTFE

25 minutes 15 seconds

WD-40 Specialist Silicone

1 hour 17 minutes

WD-40 Original

3 hours 35 minutes




Observations


Initial Application

Upon initial application, each product left a distinct wet mark on the cardboard. The visual difference between the products was noticeable, with some appearing more liquid than others.




Drying Time

The WD-40 Original took the longest to dry, leaving a pronounced wet mark even after 3 hours. On the other hand, the WD-40 PTFE Dry dried relatively faster, with the wet mark diminishing considerably within a short span.




Practical Applications

While cardboard isn't the typical surface one would apply WD-40 to, this experiment effectively showcased the absorption rates of different products, highlighting their potential efficacy in various practical applications.





JC's - Conclusion WD-40 is a versatile range of products that can be used for a variety of tasks. However, it is important to choose the right WD-40 product for the job and to consider the drying time.
