While some people may enjoy cleaning a dirty bike, I’m definitely not a member of that group. Maybe part of my attitude stems from being stuck with three dirty bikes after a ride, and the test riders have mysteriously disappeared. Welcome to the Ultimate Motorcycling Motorcycle Cleaner Comparison.
However, when faced with three dirty bikes from the same ride, it gives me a chance to compare different cleaning supplies. In this case, I had the latest formulas from Bel-Ray, Spectro, and VP Racing on hand—all three US-made. While most people might consider cleaners interchangeable, these three products all work differently.
To make things fair, I went with the alphabetical system. The Bel-Ray was used on the Beta Xtrainer, the Spectro on the Honda CRF250X, and VP Racing on the Yamaha WR250F.
Although not covered in mud, the bikes did pick up some adobe mud (especially tough), and the Honda CRF250X had a tough dirt/oil mix on the swingarm after getting upended on a particularly nasty single-track trail. If you live in heavily muddy areas, you’re going to need to knock off as much gunk before starting the washing process.
A garden hose was used to clean the bikes, as I avoid the destructive forces of pressure washers in favor of detail work and elbow grease.
Note: This motorcycle cleaner comparison was written in 2015 and is being published online here for the first time on January 30, 2026. Two products remain available and popular today—the Spectro Motocycle Wash and VP PowerWash—while the Bel-Ray Bike Wash is discontinued. Although the insights are still useful for understanding options, check current reviews for the latest formulations/prices.
BEL-RAY BIKE WASH
Bel-Ray’s clear cleaner is the most traditional of the three. You spray it all over the bike, let it sit for a few minutes, and then rinse it off. That’s simple, and it worked.
While not quite spotless, the Beta Xtrainer looked fresh and ready to ride. A wet rag removed the remaining dirt, and a dry towel finished the job. Bel-Ray claims the clear Bike Wash is residue-free and environmentally friendly—I can certainly attest to the former.
SPECTRO MOTORCYCLE WASH
While Bel-Ray tells you not to spray its Bike Wash on hot surfaces, Spectro insists that everything be cool to the touch. Given that, the bikes were washed in the shade.
The Spectro Motorcycle Wash is a much more potent blend, as you are instructed to spray it off before it has a chance to dry. In fact, Spectro says to only wash one part of the bike at a time to avoid letting the cleaner dry on the bike.
Doing that is a bit of a pain, yet it works. The CRF250X cleaned right up, including the caked-on oily dirt on the swingarm. It just rinses right off, which is an impressive trick.
Like the Bel-Ray Bike Wash, the Spectro Motorcycle Wash left a bit of dirt here and there. Again, a damp rag and a dry towel finished the job. At the end, the Honda CRF250X was spotless and bright.
VP POWERWASH
Okay, this is definitely something different. VP tells you to rinse off the bike first, which is a bit unorthodox, and then spray on the PowerWash. After a couple of minutes, rinse the bike off, as with the Bel-Ray Bike Wash.
Spraying cleaner on a wet bike seemed a bit odd, and I wasn’t really sure how well it would clean. The results weren’t quite as good as with the Bel-Ray and Spectro cleaners. There was more residual dirt on the Yamaha WR250F than on the CRF or Xtrainer, both of which had more oily dirt.
However, like the other two cleaners, this was easily solved with a wet rag to rub off whatever was missed. It wasn’t a huge difference, but the VP PowerWash was the least effective of the three on the first pass.
Motorcycle Cleaner Comparison Conclusion
Choosing the right cleaner comes down to your workflow.
If you’re cleaning two or more bikes, go with the Bel-Ray Bike Wash. You can spray both bikes in succession, then rinse them in the order you sprayed them. That saves some time and works well.
Those with just a single bike to clean might prefer the Spectro Motorcycle Wash. You can concentrate on each section of the bike and clean it to perfection as you go.
That leaves you wondering if you want the VP PowerWash. Well, the surprising answer is that you definitely do, if you don’t mind a multi-step process. After spraying and rinsing a dirty bike, and it’s still wet, give it a spray with the VP PowerWash, and the final result is nearly pristine.
These products won’t entirely eliminate the hassle of washing a dirty dirt bike. However, Bel-Ray, Spectro Performance Oils, and VP Racing Fuels make it easier to achieve the satisfaction of a sparkling motorcycle at the end of the job.
