Muc-Off Fast Action Bike Cleaner  £6.85


Easy to use and effective workshop staple for the time poor

Muc-Off bike cleaner

Muc-Off’s new formula works fast and will have greater appeal amongst the thin tyre fraternity thanks to more efficient removal of road grime. However, while certainly saving time, it’s still prone to leaving a streaky finish and despite boasting green credentials, citrus-based cleansers remain one step ahead.

It couldn’t be simpler to use and good time management is central to getting the best results. Give the contents a quick shake before spraying liberally over the bike. Leave the formula to fizz away at the gunk while you fill a bucket or two of tepid water. Accumulated filth might need persuasion from a medium/soft brush but there’s no benefit in extending the waiting times- this simply results in a streaky finish.

After five minutes give encrusted areas such as under the saddle a good tickling with the brush, dipping in the bucket as required before rising thoroughly. I was impressed at how effortlessly the grime slithered from the frame and onto the concrete below leaving a curiously appealing puddle. Buzzwords come and go but the new nano tech formula apparently employs a super invasive technology claimed to accelerate cleaning while protecting against corrosion. Wer'e guessing this means the particles of the cleaner's active ingredient are very very small. Whatever, it seems to work.

Credit where it’s due: it is very effective. But it is fairly aggressive, so we'd recommend latex or other gloves when you're working. Secondly, the Bike Cleaner could potentially disrupt grease and other wanted lubrication in headsets, bottom brackets and hubs in particular, so avoid spraying directly in these areas.


Good workshop staple for the time poor but observe directions religiously test report

Muc-Off's fast action bike cleaner does exactly what it says on the tin and this formula works better on road grime than previous incarnations. However, I have some small reservations over nanotech's invasive technology which could potentially strip seals and bearings.

If its aggressive enough that I need to wear gloves I am not spraying it on my paintwork.

I use this stuff on my bike and alloy wheels, it's awesome. But nanotech cleaner? Utter marketing bollocks, it's Nitrilotriacetic acid which is a mild biodegradable industrial cleaner and probably costs all of 1/2 a pence a bottle to make.
