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.
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.
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.
Tell us some more about the technical aspects of the product?
Paper towels soaked in isopropyl alcohol

With 20 years of road cycling and over 150,000 miles in his legs it's safe to say Stu is happiest when on the bike whatever the weather. Since writing his first review for road.cc back in 2009 he has also had a career in engineering including 3D-CAD design and product development, so has a real passion for all of the latest technology coming through in the industry but is also a sucker for a classic steel frame, skinny tyres, rim brakes and a damn good paintjob.
His fascination with gravel bikes is getting out of control too!
