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.

Juice Lubes' Dirty Little Scrubber is a seriously effective chain cleaning device that works within minutes, leaving your chain sparkling and clean. It's easy to use, cleans efficiently, and comes in at a competitive price.

Like most of these devices, the Dirty Little Scrubber works by having bristles that coat both the rollers and plates of the chain in degreaser, making for a far more efficient cleaning process than just a sponge and a rag.

I used the device in conjunction with Juice Lubes Dirt Juice Boss Chain Cleaner (it requires 20ml of degreaser) and it worked very effectively, agitating dirt and grime from the chain within a matter of minutes.

All the chain then needed was a wash off with a sponge and hot water and it was as shiny as the day I bought it.

I found 25 revolutions sufficient for most cleaning jobs, twice that for chains that hadn't been looked after in a while.

What I particularly like about the Juice Lubes over others I've used is that once it's attached to the chain, you don't have to hold it in place. It hangs from the chain and once attached doesn't move thanks to the metal attachment hook that loops round the rear mech hanger. You then backpedal or rotate the pedals by hand to distribute the degreaser across the chain. With some, such as the LifeLine X-Tools Pro Chain Cleaner, you have to hold the device to stop it from moving.

After using the Dirty Little Scrubber on over 30 chains, there appears to be no wear on the three nylon bristles, which suggests good longevity. With most cheap devices I've used these become warped very easily.

I am really impressed with this little device – it's a perfect solution for dirty chains. At £13 it even comes in cheaper than the LifeLine one reviewed on our sister site For your money you get the same effectiveness with no-handed functionality. What's not to like?

Seems excellent value to me, I purchased the Muc-Off X3 and while it does an excellent job it's more than double the price.

I've used this tyype of chain scrubber before and found that liberal amounts of solvert were dripping off the chain onto the floor and running down chain rings and sprockets.

For some years now I've been taking the chain off and dropping it in a jam jar half full of WD40. Let it soak and shake it a few times and when the bulk of the dirt is off do it again in a second jar of WD40. Looks like new afterwards and no crunching noises that you get from using a rag on the chain that pushes fine grit between moving parts.

I leave the jam jars to stand and let the dirt settle then decant the clear WD40 and flush the dirt out. That uses some liquid that only needs topping up!

For those that may not be aware of it, WD40 is available in 5L canisters.

Paraffin oil is a fair amount cheaper than WD40 and very commonly used to degrease motorcycle chains. You can get 5l for about a fiver

Sounds like a good product. The name seems a little, er, démodé, though.

5 stars, well done Juice Lubes.

I do like their fork juice.

I had to adopt KMC chains when Sram stopped making nice 8 speed chains, they advise against solvent chain scrubbing, so didn't.  Little more wiping and an acceptance that the drivetrain on the Getting to Work bike (now mothballed) would never sparkle at the very start of the one journey just after cleaning.  There is less taking the casette off for deep cleaning too, just flossing.  No need chain is not super clean.

The good bike still has a nice Sram 9 speed and XTR, so that one still gets scrubbed, and of course I am much more obsessive about that one.  Still the sparklyness only lasts until the first bridleway.

The Ultimate Commuter is Rohloffed, KMC's X1 is a tough old chain, though VERY good, when new it cannot fit my Park CC-2 chain checker and so appears to have less than 0% "stretch" (whearas new derailier chains come in at around 0.25%, as expected), KMC so only wipe (very well) and occasionally toothbrush to rid some of the inner filth.  Much less time needed to get a nice level of cleanlyness on the "single speed" setup.

I do not seem to notice a huge difference in life of the chain when using or not using my Park scrubber and Finish Lines Eco Tech solvent.  Never been one to keep records, just change things when needed, preferably with the best I can manage.

To Sirachas point, not using the scrubber does seem to result in less of the grinding thing when twisting the chain with fingers between cleanings.  Maybe KMC have a point and their excellent set up grease does stay in the deep crevices and keep the chain lubricated.  My riding is a bit of road (utility) and a lot of off road with dust and/or filth.  Lots of filth.

I've gone wax now. So far, so blissful. Clean chain stays clean. I'll see how it pans out.

Hirsute | 3 years ago

I don't know if you are supposed to do this sort of thing. Some say yes, others say it messes up the inner lubrication and your chain is never the same again.

Sriracha | 3 years ago

The chain certainly looks sparkling. Did you try flexing it side to side? I always get a gritty sound and feel when I try that, telling me that there is still grit in the inner workings. And of course, how long will it stay clean?

I always deferred to Sheldon Brown for proper cycle maintenance. His chain cleaning methodology being particulary thorough

I've just read that. O. M. G. 


The only proper way to clean a bicycle chain is to disassemble it, otherwise there is no way to be sure you've thoroughly cleaned and properly lubricated the critical internal parts where chain wear occurs.


Use your chain tool to drive each chain pin halfway out. It only has to go far enough to clear one of the outer plates.

The 'real' page is not much lighter, invoking religion and philosophy, and includes the suggestion to boil the chain, thoroughly, both sides up!

The bit that grabbed my attention in that was that 'all of these existing systems are fundamentally mono-buttocked kluges.'

I'm now left pondering whether being mono-buttocked would make Roger a greater cyclist or a lesser one. I imagine he'd certainly need some kind of custom saddle though.
