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.

Good scores are more common than bad, because fortunately good products are more common than bad.

Proper Cleaner by Guy Martin's Proper Degreaser comes with two sachets, which is enough to fill the robust plastic bottle twice. It's a good idea that avoids the waste of shipping tons of water around a generally very watery planet, but unfortunately the result is just bad at degreasing things.

Having carefully followed the instructions for mixing this, and further followed those to spray it on a wet surface and leave for three to four minutes, I went to the next step: 'agitating' my oily black chain. Five minutes later, only I was agitated.

The lube (only a few rides old on a brand new chain) was only partially broken down, smearing messily and remaining sticky to the touch. I liberally blasted the whole lot with more Proper Degreaser, waited another three minutes and tried again. Same thing.

Eventually I gave up and used something else. For the record it was Fenwick's Bike Cleaner (£7.99 a litre, refillable from concentrate), which took the same stuff straight off.

The effect of Proper Degreaser on the dust-filled marine grease around my lower headset was the same – negligible.

It's very disappointing as – until you try it – this stuff is impressive. It's a good idea to remove the weight of the water when it's so easily added after shipping, and the bag containing the sachets is resealable to preserve the spare.

The cleaner is vegan-friendly, biodegradable and 'not tested on Nigel or his mates' – Nigel, it turns out, is Guy Martin's dog.

Also, while the bottle is plastic, it (along with the spray head) feels rugged and should withstand plenty of use and refilling. It's all very worthy. It's a genuine shame it's not also worthwhile.

I'm not a fan of food-scented cleaners, and it's worth mentioning – at least if you have young children – that this stuff smells utterly delicious. It's like strawberry Hubba Bubba. It genuinely makes me want to drink it, and I'm 48 and at least theoretically an adult.

While I've had great results from the Fenwick's mentioned above (cleaning, not drinking), if you just want to melt stuff then Tru-Tension Cycle Drivetrain Cleaner is a powerful, solvent-based aerosol for the same £10 as Proper Degreaser – but 500ml instead of 1.5L. On the other hand you don't need much, as it works.

Back in the eco corner, Green Oil Agent Apple Extreme Immersion is environmentally friendly and works very well, though it's more expensive at £12.99 for 300ml.

Given the thought that's gone into this, and the need for a more eco-friendly approach in general, it's a real shame it's so ineffective. I wasn't expecting it to work like trichloroethylene and melt the prints right off my fingers, but I was expecting it to at least match other biodegradable products. Unfortunately, it's the weakest degreaser I've tried, to the point where I found it useless.
