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.
The Juice Lubes JL69 bike maintenance spray is, according to the blurb, "Your crowbar wielding mechanic in a can." OK, bike shop shelves heave under the weight of such claims, and nobody really wants their mechanic using a crowbar, but JL69 is a heavy duty, long-lasting water displacer/penetrant/lube that delivers on the hype.
This redesigned JL69 is blended to cling to your bike, unlike typically thin water-displacers such as WD-40 which themselves are quickly washed away by rain. It contains no PTFE either – polytetrafluoroethylene, best known by the brand name Teflon – so theoretically it's much kinder to rubberised components and of course, organic life.
JL69 uses a smart-type straw that only deposits when aligned horizontally. This avoids unwanted and wasteful discharges, and is controllable enough to, say, fill an Allen head bolt accurately.
It leaves cables feeling particularly well-nourished and, unlike the otherwise excellent Green Oil EcoSpray Lube, there's no hint of it congealing with time. Used externally, JL69 cultivates a light, filmy patina but isn't overly prone to collecting grit or grime.
This stuff can even double as a fair-weather chain lube – I got 250 miles from a single (admittedly generous) application.
At £5.99, JL69 matches generic sprays such as GT85, and beats some bike-specific products such as Green Oil EcoSpray Lube at £7.99. However, JL69 lingers longer and is closer to a 'proper' lubricant than GT85, and avoids the gumminess of EcoSpray.
You can find cheaper alternatives, such as BTwin's All-In-One maintenance spray at £4.99, which is similarly durable and versatile (and still £4.99 all these years after that test). However, like GT85 it contains PTFE, which isn't too kind to electrical contacts or rubber seals.
JL69 is a great middleweight option where light but lasting lubrication is required. It can also loosen corroded parts. However, look to something like GT85 and the original WD-40 if you prioritise a light lubricant/water displacer for flushing moisture from cables, accessories and components.

road.cc test report
Make and model: Juice Lubes JL69 Bike Maintenance Spray
Size tested: 400ml
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?
Juice Lubes says: "New formula JL69 is a do-it-all workshop essential that lubes and protects, drives out moisture, resists rust and stops dirt sticking to your bits."
My feelings are it's a versatile middleweight lube that does most things very well. However, seized parts call for a release/penetrant spray – this is more for flushing things through.
Tell us some more about the technical aspects of the product?
Juice Lubes is very tight-lipped about ingredients. I can confirm it doesn't contain PTFE.
Well blended and smart straw similarly well designed.
Excellent for most generic workshop duties, a little goes surprisingly far and lasts a good while.
Longer lasting than most maintenance sprays.
Tell us how the product performed overall when used for its designed purpose
Overall, I've been very impressed by JL69's lasting lubrication, keeping cables, cleat locks and similar mechanisms slick and happy. Hinges and linkages remain slick several weeks down the line and there's been no call to reapply. It will help free stubborn parts but, despite being free of PTFE, water displacers like WD40 are what you need on corroded light switches/battery contacts.
Tell us what you particularly liked about the product
Safer on seals than PTFE types, excellent staying prowess and does most jobs very well.
Tell us what you particularly disliked about the product
How does the price compare to that of similar products in the market, including ones recently tested on road.cc?
The price is very reasonable against generic sprays such as GT85 and WD-40, and cheaper than some bike-specific products such as Green Oil EcoSpray Lube at £7.99.

Use this box to explain your overall score
This is a long-lasting, middleweight lube that does most generic workshop duties very competently, and it's well priced. There's a lot of competition in this area, but JL69 is good and a seven.
