GCN 5 minute bike clean

Just been watching the below, GCNs 5 minute bike clean. Looks like a pragmatic approach, but I'm guessing the wd40 as a lubricant may divide opinion?

once the solvents finish displacing the good lubricant together with any water, they'll evaporate and leave just a thin film of light oil
if thin films of light oil were good lubricants you'd find them in new chains. hubs, bb bearings, car transmissions, engines, etc. etc., but they're not good, so what you find are much heavier oils or even greases
btw hilarious video, spraying wd40 onto the brakes, what a plank!
WD-40® literally stands for Water Displacement, 40th formula.
oh, agree with Sungod, spraying WD40 on your brakes, FFS.
I thought (i watched it a while ago and i'm at work now so can't check) he just used it to clean the bike then used a separate lube afterwards?
Oh he does use WD40 as a lube but admits it's a contentious decision.
*caliper. It's not exactly the brake blocks, is it?
It is a very pragmatic approach; I'd rather do a 5' clean every day or so than a 1hr clean each week.
To help explain the WD40 as a 'lube', my own experience suggests (as he notes) that it only works if you already have lube on your chain and haven't used a full on degreaser. I'd guess, as you're not degreasing the chain fully, it thins out some of the existing lube that isn't washed off (as it's only a quick wash) and redistributes it over the chain more evenly. Hell, the WD40 website even says that it's a myth that it isn't really a lubricant. Plus, what McStumpy says.
Seems to work ok for me when done daily.
Of course they do. But this is an internet forum where everyone is an expert.
Your bike will look good but it will ruin the bearings as soon as soapy water reaches the internals.
Maintenance just for the eye.
In the pro world it's often done this way, but a mechanic has to make a lot of bikes "clean"(for the eyes of spectators) and you can afford apply the best for your bike, that's the difference.
The only useful application for WD40 is spraying the chain clean after a wet ride on holidays and only when the chain is lubricated afterwards.
Otherwise WD40 should be kept away from racing bikes ever.
me too, B and M bargains or similar shops usually have the big tubs for about 3 quid, get the chain clean as quick as anything I have tried. makes you wonder what they do to your skin!!
