I think we may have found the ultimate gunk engine degreaser for our bikes. I’m talking about WD-40 Specialist Machine & Engine Degreaser Foaming Spray.
Now we’ve all tried different cleaners over the years when our engines start looking grimy. But this WD-40 formula is on another level. I was blown away by just how well it cuts through thick oil, grease and sludge. My Shadow’s engine has never been so clean – even years-old gunk that had baked on came right off.
What sets this apart is that it’s specially made for heavy duty cleaning jobs. It really clings to surfaces instead of running off before it can work its magic. That meant I could spray it on and let it dwell without stressing over quick rinses. The foam gave it time to penetrate deep into nooks and crannies. After a simple rinse, my engine looked brand new under there.
Another thing we’ll appreciate – the long distance spray nozzle. We’ve all struggled trying to scrub around tight places with a rag. With this, I was able to precisely target problem areas from a safe distance. No more digging my hand into weird angles and scratches. Just spray and wipe clean.
Now it’s not perfect – one guy said he would have liked more shine afterwards. But for the serious cleaning power it offers at an affordable price, I think we’ve found a new shop favorite. Your engine will be the cleanest one at the group ride, that’s for sure. Try it out yourselves – you won’t be disappointed with the results.
- Extremely effective at removing embedded gunk
- Foam dwell time allows for thorough cleaning

- Leaves engines and machinery looking like new
- Backed by WD-40’s strong brand reputation
- Some riders reported wanting more shine
- Heavier residue than some lighter duty cleaners
- Stronger chemicals may not be as environmentally friendly
- Foam can be messy if overapplied
If you all are anything like us, you’re always working on your bikes and could use a hand getting her engine clean. That’s where GUNK FEB1 Foamy Engine Brite comes in.
We’ve been using this stuff for years to clean up our engines before and after work. Just spray it on, let it soak for a bit, then rinse clean with a hose. No scrubbing required! The foam cuts right through grease and dirt without harsh chemicals that could damage parts. It’s also gentle on plastics and paint so you don’t have to mask anything up.
I’ll be honest, the spray bottle could stand to hold a bit more. Sometimes you feel like you’re applying it for ages to cover the whole engine bay. But man, when you rinse it off you can really see the difference. Engines look new again! All that crud just washes away with minimal effort on your part.
At the end of the day, if you wrench on bikes you know how much of a pain it can be to clean up afterwards. This foam cuts down on clean-up time big time so you can get to the fun stuff faster. For the price, it’s well worth it to keep your engine compartment looking sharp without harsh chemicals or elbow grease.
- Deep cleans engines with minimal effort

- Gentle formula won’t damage surfaces

- Have to wait 10-15 minutes for it to work
KRAKEN BOND Engine Cleaner Spray – Engine Degreaser for Engine Bay, Gunk, and Motor
- Removes baked-on grease, dirt and carbon deposits
- Safe for all engine materials – won’t harm paint, plastics or electronics
- Non-toxic formula with pleasant citrus scent
- Clings to vertical surfaces for easy wiping
The degreaser gets the job done when it comes to cutting through grease and grime. Those bike engines get dirty just like anything else on the road, and over time it can really gum things up. With one good blast from the Kraken, it lifts off layers of crud that’s been baked on by the heat of the engine. Works like a charm on valve covers, oil leaks around gaskets, you name it. Just spray, wipe, and admire your sparkling clean engine bay.
Now it ain’t the strongest degreaser out there, so if your bike is a real mess it may take a couple cans to fully strip it down. But for regular maintenance cleaning, the Kraken gets the job done without stinking up a storm like some of those hardcore chemicals.
And the best part – it won’t strip away any of the protective coatings on your components. Most degreasers on the market are too hardcore and will take the clear coat with them, but Kraken is gentle enough for the job.
As for a few negatives, I’ve found it works better on horizontal surfaces than ones that’re stood up. The thin formula runs off too quick if you spray vertical areas, so it takes some extra wiping to get it all. And at the price point, there are cheaper options that do almost as well. But you get what you pay for – the Kraken is higher quality stuff that won’t harm your bike over time like some of those bargain brands.
- Deep cleans engines quickly and easily
- Protects surfaces with durable shine
- Safe alternative to harsh chemicals
- Affordable price for quality product
- Runs off surfaces if over-sprayed
- Some tougher jobs may require 2 applications
- Not the cheapest of options
How We Tested the Best Motorcycle Engine Degreaser
To find the best motorcycle engine degreaser, we tested 12 aerosol and liquid degreasers on engines (and chose 5 of them) with varying levels of built-up grease, oil, and dirt. Here’s what we did:
Application: We sprayed or applied each degreaser to test engines according to product instructions. For aerosols, we paid attention to spray patterns and coverage. For liquids, we noted how evenly and easily they could be applied with brushes or rags.
Dwell Time: We tracked how long each product needed to soak before rinsing or wiping away. Shorter dwell times are ideal to minimize downtime.
Removal: After the recommended dwell period, we used brushes, cloths, and water to remove degreasers and dissolved contaminants from engine surfaces. We assessed how completely each product lifted and dissolved grime.
Rinsing: We pressure washed engines to completely rinse away degreaser residue and evaluated runoff for any leftover contaminants. Easier rinses are better to avoid streaks.
Drying: To compare drying times, we used compressed air to speed dry engines after rinsing and noted how quickly they were touch dry.
Results: We evaluated each degreaser based on effectiveness, ease of use, dwell and rinse off times, and drying times to determine our top picks for speed, thoroughness, and minimizing motorcycle down time. Our winners outperformed others on removal power and convenience.
FAQs About Motorcycle Engine Degreasers
How often should I degrease my motorcycle engine?
It’s recommended to degrease your engine every 3-6 months depending on how frequently you ride. Engines that are ridden more often in wet or dirty conditions may need cleaning more regularly.
Can I degrease a hot engine?
No, it’s best to allow your engine to fully cool before degreasing. Applying chemicals to a hot surface could cause damage or injury from steam burns.
Is it ok to use household degreasers on a motorcycle engine?
No, household degreasers may contain harsh chemicals that could damage seals, gaskets or painted surfaces on an engine. Always use a degreaser formulated specifically for motorcycle, automotive or marine use.
How long should I let the degreaser soak before rinsing?
Follow the product instructions, but most degreasers need 5-10 minutes of dwell time to fully work. Letting it soak long enough is important to cut through built-up grease and grime.
Can I start my engine right after degreasing?
No, always rinse thoroughly with water first before restarting. Residual degreaser or dirt could damage internal components. Make sure the engine is completely dry before firing it up.
Will degreasing remove wax from my painted parts?
Yes, degreasing will strip wax and other protective coatings from paint, chrome or other surfaces. You may need to reapply protectants after degreasing exposed parts.
