A Family Foundation

The Superior name carries a legacy of hands-on, done-right service. Superior Fluid Solutions is led by Derek McIalwain(son), whose background spans over a decade in education before turning his focus fully to building and growing service-based businesses in the Inland Northwest. Having served the Spokane are for over three years with Superior Upkeep a small construction company. Derek is very excited to take on the ability to serve alongside local businesses with Superior Fluid Solutions. Partnering with Derek is Dean McIalwain(Father), whose experience in sales spans over 30 years. Dean has been running a local Spokane business for the past 8 years with great success. His understanding of the local economy is just what you need to help grow your profits.

Together, Derek and Dean bring a rare combination to the table: the discipline of long-term relationship building and the operational know-how to run a distribution business that you can actually rely on. Being a father/son team means a lot to us and we hope to share that in a partnership with many businesses spanning throughout the Inland Northwest.

What We Do

Superior Fluid Solutions distributes the trusted Wynn's line of automotive chemical products, alongside the everyday essentials shops and dealers need to keep operations moving — gloves, hand soap, paper towels, fasteners, license plate frames, dealer paper plates, and more. Our goal is to simplify procurement for our partners, consolidating multiple vendor relationships into one dependable source.

Our Approach

We believe distribution should feel like a partnership, not a transaction. That means responsive service, consistent restocking, and a team that understands the day-to-day pressures of running a shop. As we grow, we're committed to expanding our product offering thoughtfully — always with an eye toward what genuinely helps our accounts run better.

Built to Last

Superior Fluid Solutions is a family business built on trust, reliability, and getting the job done right.
