Juice Lubes Dirt Juice Hero



Reasonable anti-lube but distinctly average when pitted against other brands

At 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.

Juice Lubes' Dirt Juice Hero is in fact a drivetrain degreaser – the "ultimate" – and one it reckons is the fastest going. Spray on, rinse any residual gloop and kaboom!!! Your drivetrain is gleaming...

Other than telling us that it's a super-flammable cocktail that is toxic to fish, mustn't be used near sources of ignition and stored in cool dry places, the exact ingredients are a mystery. However, it seems based around butane propellant and petrochemical rather than organic solvents. Common sense suggests minimising contact with rubberised components and unsealed finishes.

Its arrival coincided with several new chain lubes, the sort that spit the dummy unless recipients are surgically clean. My Holdsworth TT bike had been fed a fairly bog standard Teflon/mineral oil formula for several months, my Univega a highly sophisticated ceramic.

Given the blurb, I was literally expecting to blast one minute and be introducing new lube the next. While organic debris literally fell away, even the more basic 10w/40 and PTFE-based preps needed three applications and stiff brush coaxing in between.

Clipping on the chain bath and squirting inside while turning the cranks certainly helped. By contrast a store brand degreaser virtually licked both variants clean on contact and promptly evaporated.

While marketed as a drivetrain cleaner, I couldn't resist testing its prowess on other oily, greasy stuff.

>> How to clean and lube your bike chain 

Having stripped my fixed-gear winter bike/trainer ready for the frameset's powder coat makeover, I bundled chain, sprocket, crank bolts and headset races into an old 5kg chocolate punnet and blasted them with the Hero.

Credit where due, it certainly loosened the PTFE and lithium pastes pretty convincingly, but subsequent squirts and more stiff brush action were needed before the surfaces were satisfactorily clean. Two liberal helpings, followed by enthused scrubbing, had the stainless steel chain gleaming.

Overall performance isn't bad, the blurb just promises more than it can actually deliver. Even allowing for the fact that lubes are increasingly resilient and anything too potent has implications for seals and other rubberised components in the longer term, several cheaper competitors do a much better job.

Make and model: Juice Lubes Dirt Juice Hero

Size tested: 600ml

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

The Juice Lubes Dirt Juice Hero is a drivetrain degreaser with considerable promise.

Juice Lubes says: "If you want superhero-like speed and power when it comes to getting your drivetrain looking and working like new again then look no further – Dirt Juice Hero is here to save your ass! Nothing else gets rids of grease and drive train gunk quicker than this".

In reality, it's good but performance doesn't match the hype, or indeed several cheaper formulas.

Tell us some more about the technical aspects of the product?

600ml aerosol (butane propellant/solvent mixture) which isn't particularly kind to the environment, so use in well-ventilated areas away from waterways/aquatic life and store in a cool, dry space away from sources of ignition.

Tell us how the product performed overall when used for its designed purpose

Overall performance is reasonable on most types of lube and more traditional lithium/PTFE fortified grease, but citrus-based formulas are more economical and two spray-on brews (one budget, the other similarly priced) blitzed chains, cassettes, sprockets and chainrings within seconds.

Tell us what you particularly liked about the product

Convenient and fairly efficient at tackling more traditional 10w/40, mineral oil/PTFE chain lubes and their organic contaminant.

Tell us what you particularly disliked about the product

Lacked the same bite as many costing considerably less, especially when dismissing sophisticated petrochemical lubricants.

Did you enjoy using the product? Yes

Would you consider buying the product? No

Would you recommend the product to a friend? I'd say it was slightly mediocre – there are more potent formulas with much smaller price tags.

Use this box to explain your score

Distinctly average given the ultra potent hype. I was expecting something that would literally strip chains and cassettes in seconds. Other cheaper blends work a lot faster – without any input.

Overall rating: 5/10
