At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.What the road.cc scores mean
Good scores are more common than bad, because fortunately good products are more common than bad.
Green Oil Agent Apple Degreaser will take on some tough challenges without relying on any petrochemicals, using fermented fruit extracts instead. GO claims it is perhaps the most powerful bike degreaser available, and considering the state of my chain and cassette at the beginning, I'm inclined to agree.
Right, this stuff is strong, so that 'con' about it making your fingers tingle isn't an issue if you use gloves. I didn't have any, and to be honest I'm not that bothered about immersing my skin in fruit extracts. If you have sensitive skin, though, take precautions.
Performance-wise, though, I'm impressed with the Agent Apple. This is a new recipe created since we last reviewed it back in 2015.
The chain and cassette you can see in the pics were new for the winter in 2020, and had done about 4,000 miles before the bike got bunged in the shed with the intention of having all of the salt and grime cleaned off it.
With the amount of test bikes coming through, though, my Kinesis, which the chain and cassette were fitted to, was left to fester. Normally I'd replace the parts in September, ready for the rainy season, but with the current prices and lack of availability, I had to make do with what I had.
I had cleaned both, but after a soak in the Agent Apple they have come up pretty spanking.
Between the before and after pictures, the cassette was literally soaked for about five minutes and came up near spotless with just a wipe off with a cloth.
The chain took a longer soak, the two hours recommended by Green Oil, and I'd say that has come up pretty well. This bike only ever sees wet weather, so the drivetrain gets a lot of abuse.
All the crap that has accumulated around the chain pins was removed, giving it a much smoother operation and ready to be re-lubed.
Ingredients-wise, Green Oil has used plant-based alcohol from EU grown sugar, fermented apple extracts and orange peel.
If your chain has Covid-19, it'll kill that as well!
Green Oil says that you can use this degreaser three times over, and I'd say that is true if you are using it on some seriously dirty components. After I'd used it for an initial deep clean, I used it on the chain every week by daubing it on a cloth and giving it a wipe to keep it clean, which makes it usable many times over.
That helps when you're looking at the price: at £14.99 for 300ml it's pricey compared with some: the 1 litre of Morgan Blue Professional Chain Cleaner for £11.95, for example. There are no eco-credentials there, though.
Adam was impressed with the Juice Lubes Dirt Juice Boss Chain Cleaner. He reckoned it worked really quickly, although we're talking £14.99 for half a litre.
At £14.99 for 300ml the Agent Apple isn't cheap, but performance-wise I reckon it is pretty impressive.
Not cheap compared to some, but impressive cleaning power should you neglect your drivetrain

As part of the Tech Hub here at F-At Digital, our senior product reviewer Stu uses the knowledge gained from putting well over a 1,000 products through their paces (including hundreds of bikes) to write in-depth reviews of a huge range of kit. After first throwing his leg over a race bike back in 2000, Stu's ridden more than 160,000 miles on road, time-trial, track, and gravel bikes, and while he's put his racing days behind him he still likes to smash the pedals rather than take things easy. Although, as he spends a fair bit of his time reviewing ebikes these days he's becoming an expert in letting the motor take the strain. He's also waiting for 23mm race tyres to make a comeback!
