WD40 3 in One Professional - Bike Maintenance Spray



Good lightweight spray lube but not thick enough for chains

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.

What the scores mean

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

WD40 3 in One Professional Bike Maintenance Spray is supposedly cycling-specific, but it does a whole lot besides and very well too.

Frankly, aside from the handy size 250ml aerosol, performance wise there's a fag paper separating it and the wealth of chemically similar products arriving at the offices these past few weeks. No excuses for sticky shifts, scabby fasteners and squeaky cleats in my fleet then.

Here we have another petroleum based solvent brew with our old friend PTFE thrown in to lower friction and retard corrosion. Solvents enable mixtures to be applied in a sprayable format, speeding them to the affected areas, removing grease, oil, tar and dirt, leaving white waxy lubricant clinging behind.

Despite WD40's suggestions to the contrary, I found it very much a light dressing, meaning it's not suitable as a chain lube.

Control cables, pivots, freewheel mechanisms and contact points that have become sticky (as opposed to royally stuck) are the obvious candidates. A liberal squirt and leave to marinate approach works best.

Light mists applied over paintwork/electroplate and buffed with fresh rag impart a relatively clean barrier, mimicking the traditional practice of 'greasing up' amongst motorcyclists during the winter months. This can be left to cultivate a grimy, protective layer but it's worth remembering maintenance sprays will also dissolve pre-existing car-type polymer waxes.

Those shuddering at the thought of gloop sloshing inside ferrous tubes will be pleased to hear ours worked very well as a frame flush, driving moisture and other nasties out following prolonged, wet rides.

What kind of performance you get out of it will vary depending on season, riding style and conditions but the fleet's cables remain super slick after one squirt, two weeks and 250 miles, while a set of nickel-plated cleats have been outside in coastal air seven days running with no hint of freckling.

There's no doubt this is another competent do-all light lube for generic bike and workshop duties. Cleans, protects and lubricates cables, locking mechanisms and a host of other stuff besides. However,its not stiff enough for chains, cleat mechanisms and similar drivetrain parts.

Versatile,good value, stays where it's put.

Quick question would this work as a base layer (more penetrative) to heaver wax/ptfe dry lube on a chain. Or would its petroleum solvent render this unworkable?

You could use it that way, but I would advise you to allow it to fully dry before applying "proper" dry lube.

It (or in my case GT85) gets used to blast out crud the night before an intermediate lubing and is also used to disperse any water left after a full chain strip (in a certain petroleum based solvent)and rinse.

Have a look around the forums of t'internet and you'll find a million ways of using this stuff and how best to clean and lube a chain. Many methods work, and its ultimately a matter of personal preference that dictates whats "best" for you.
