Verdict: 
Sensible emergency fix for commuters or tourers running hydraulic disc brakes

Disc brakes are springing up all over the place in the roadie market with the majority of them being put to work on all weather training and commuting bikes. Winter is here, so Weldtite's Dirtwash Disc Rotor Wipes are probably a sensible thing to keep in your rucksack.

Aimed primarily at the mountain biking community the Rotor Wipes are basically paper towels which are soaked in isopropyl alcohol. As a solvent it's intended here to clean pretty much anything off of your disc rotor to stop poor braking due to contamination.

For £1.99 you get six individual wipes in their own sachets all packed away in a plastic case. They'll remove dirt and grit but more importantly oil and hydraulic fluid. Now I know the majority of maintenance is carried out at home so these might not get a lot of use but they are intended as an emergency mid ride solution to brake fluid leaking onto the rotors or some over zealous chain lubrication.

I've tried them on pretty much every concoction I could find in the shed and the wipes removed it all while also leaving no residue on the rotors or your fingers. One wipe will clean both rotors though you've got to be quick as the alcohol evaporates pretty rapidly from the towel and it'll be dry before you know it.

Overall while they might sit in the bottom of your commuting bag for a while they are a worthwhile investment if you are running discs on the commute or touring especially if said brakes are hydraulic. At 33p a wipe it's not a huge investment either.

Verdict

A sensible emergency fix for commuters or tourers running hydraulic disc brakes

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?

Designed primarily for off road riding they do have applications for the road too. Touring with hydraulic discs could see leaked fluid on the rotor, a wipe off with one of these would them make laden descending safe again.

Stu knocked out his first road.cc review back in 2009 and since then he's chucked the best part of seventy test bikes around the West Country, a couple of them quite literally! With three alloy and two steel bikes in his fleet he's definitely a metal man (that'll be the engineering background) but is slowly warming to that modern carbon fibre stuff along with fat tyres & disc brakes.
It's not all nostalgia though, after spending the last few years in product design Stu keeps banging on about how 3D printing is going to be the next big thing and he's a sucker for a beautiful paint job too.

Every now & again Aldi sells boxes of glasses cleaning wipes (50 for £1:99), They are alcohol wipes, might not be as good as the weldtite ones mentioned above but they have come in very handy for cleaning hands, rotors, glasses, pretty much anything. I always carry a couple in a jersey pocket for those sticky fingered occasions.

They ought to come with a health warning. The edges of rotors are like razor blades and make short work of slicing fingers.
Be careful out there.

Really? I have, over the years, jammed my fingers in spokes, stabbed them with cable ends, abraded my thumbs on chainrings and barked my shins on pedals. But, having never come across a razor-edged brake disc, I tend to think they are an urban myth.

Mainly aimed at MTBs?

If you've got leaking brake fluid on an MTB, it's because you've ripped off the hose! No wipe is fixing that.

As far as contamination, just find some dirty water / mud, ride through it and hit the brakes and that's gone...

If worse than that, your pads are f-ed and you pop in new ones.

Disc rotors are NOT like razors! You can hurt yourself in any number of ways on a bike wet-wiping your disc rotors will not be one of them.

Mike & barbarus. They're not razor sharp, but you certainly can injure yourself on disc rotors, trust me. My personal recommendation would be not to inattentively allow the end of your finger to stray into the holes of a rotating disc rotor where it is about to enter the caliper. The inertia of the wheel means that the edges don't really need to be that sharp.

Or you could just buy a box of 100 pre-injection swabs for less than £2

Exactly the same product in a different package without the 1000% mark up.

Dirt wipes: £1.99 for 6 or 33p per wipe
Sterets: £3 for 100 or 3p per wipe

They'll clean chain gunk off your hands too, but they will dry out your skin in the process, so don't make a habit of it!!!

In my 10+ years of riding with discs I have never once found myself thinking 'I wish I had some wetwipes to clean my rotors with'. How would you get chain lube on your rotors while out riding? And if hydraulic fluid has splashed onto your rotors on the trail you have bigger problems than a dirty rotor.

I can assure you that the edges of the Avid Clean Sweep rotors on my bike are like razors. I've had the plasters to prove it.

Let's be honest, some people could injure themselves on a damp flannel. I blame the 'elf an' safety generation.

And apparently they are often super heated as well, increasing the risk of death by dismemberment and cauterization. Soon there will be a campaign to encourage the UCI to refrain from allowing the use of disc brakes in the pro peleton .... what's that you say?

So, where does this leave disc vs rim brake debate?? These discs sound real dangerous - you could lose a limb just servicing them, apparently. So maybe, I'll just take my chances out on the road with rim brakes.  3

You might need to work on the maths for that a bit longer!
