Fenwicks FS1 Bike Cleaner Concentrate & Degreaser
Fenwicks FS1 Concentrated 1 Litre, Makes 11 Litres of bike cleaner from 1 litre.
FS-1 Cleans CARBON and MATT frames, leaving them with a perfect finish, it always has done and always will do. Why pay extra? For expensive, overpriced cleaners
Fenwicks FS-1 - No acids or solvents, ideal for all bikes
In 1996 we created our first bike cleaner concentrate called 'Hog Wash' If any of you have a bottle drop us a line. This was way ahead of the curve as it didn't take off due to the already mixed, ready to use bike cleaners out there. Relaunched in 2003 as FS-1 because of our belief in giving you value for money, the demand for FS-1 Bike Cleaner Concentrate increases by the day as there are now lesser concentrates on the market. This is because 1 litre of FS-1 can make up to 11 litres of ready to use bike cleaner, making it £0.91 per litre, a no-brainer really. We even have a special fill line on our FS-10 bottles at the bottom to help you out creating the perfect bike wash every time.
Like no other company we produce such highly concentrated cleaners using a complex blend of high quality liquid raw materials (others use cheaper powdered raw materials, which can leave a powdery residue when dry) FS-1 Bike Cleaner Concentrate cleans deeply and easily to leave exceptionally clean contaminant-free surfaces. Safe for you, your bike and the environment. Free from caustics, metasilicates, abrasives and silicone. Safe for use on all bike parts including carbon fibre, disc brakes, delicate anodized parts, etc. Plus it's strong enough to be a great degreaser.
How to use FS-1 as a degreaser

Karen Love this cleaner, unlike muc-off it doesn't move grease from one surface to another. My chain scrubber doesn't require soaking in washing up liquid to remove the yuk after use. Fenwicks cleans it at the same time as your chain. MY drivetrain is spotless. It doesn't harm the environment either. Highly recommend it.
Mr Woodhead Great value for money cleans well on par with muc off
Ed This is the cheapest and best way to get bike wash. I use it either neat for the chain or diluted for the rest of the bike. It only takes a second to mix up a batch in an old bottle.
Mr Wenn Way way better value than ANY other bike cleaner as much ore concentrated. You will need a spray bottle to dilute this into, but use very little to get correct mix, so 1/3 cost of the pink stuff, and cleans 95-98% as well IMO. Smells nice. Fully biodegradable too. More enviro as use less and in a bottle that can be recycled and not a pouch that can`t, like the pink market leader.
Chris The best bike cleaner that money can buy at the lowest price out there! Clean your bike without the harshness of other bike cleaners. This is also environmentally friendly and we use it to clean our boat whilst in the water also! Certificates are available for this on the Fenwicks website.
Mr Simpson Just used as a de-greaser so far - works fine
Mr Chaldecott Great product. Have used many times before. Works as spray on cleaner when diluted and also chain degreaser! 👍
Mr Drury Great product used neat & diluted - used this product for several years.
Mr G Does what it says on the tin. Good that it can be used as general bike cleaner if diluted or degreaser if used as concentrate.
Andrew Does what it says on the bottle. Cleans my bikes up in no time. Due to it being a concentrate it also lasts for ages.
Mr Bowman Effective degreaser, used neat, for cleaning the drive train and a good general bike cleaner when diluted. Good value.
wayne Still the goto product for bike cleaning :)
Mr taylor I've used this for years. It cuts through the grime and cleans wonderfully well. Highly recommended. Good price and swift delivery.
Richard I really like Fenwicks bike cleaner. I have been using it alongside another (pink) leading brand and I think it has the edge. The concentrate is really good as a chain degreaser and requires little effort with a small brush to loosen the crud before hosing off. In its diluted form its a great all round cleaner for your bike too, leaving it nice and shiny. The other plus is its also cheaper than the other make. Highly recommended.
Josh Top all round cleaner
Marc Good when used as a cleaner - not messy, rinses well. Also fairly good degreaser.
Mr Brisley Wow, Fantastic product. Used neat on drivetrain it cleans really well. Leave it to soak for a few minutes the grease and dirt are left on the floor. Diluted it gives a great wash product too. Nice quick delivery too.
DC Excellent degreaser and all-round cleaner... even when used sparingly! There is obviously a best practice approach to (properly) cleaning a bike and when followed, Fenwicks left my bike frame and wheels with a lovely shine, my drivechain looking like new and allowing me to properly and carefully re-grease the necessary components without the fear of mixing grit in with new lubricant. Top stuff and smells good too!
Stu Need to make the solution stronger than recommended to be as powerful as muc off but still works out much better value. I use one of those 2 litre pump action garden sprayers that are cheap on ebay. Will buy again.
Gareth Not found anything better than this degreaser, and diluted it cleans the bike well too
Andrew Love this cleaner especially used neat for cleaning your chain
Gold So far so good. Seems like good stuff but only just started using it against muc off
MARTCYCLING First time I've used this product, but I`m very happy, even cleans my alloy car wheels, very good value.
Mr Marriott Very effective cleaner for removing dirt from the bike, used straight from the bottle it worked well as a degreaser for my chain, I used it in a chain bath. Only slight negative is that the picture shows an outdated version, the item I received was the same shape but the colour of the liquid was green. Overall very effective, would buy again!
Flawless154 Andrew Lawless Does the job, one of the better products I have used at this price point. Won`t hesitate to get it again.. Great service and delivery from Merlin
Mr Brookes Easy to use bike cleaner, use as a concentrate or diluted. Great value.
Elder I use this a lot and it goes a very long way
CyclingDave Works a treat, smells fine. I use it by applying on with a paint brush, and the chain bath. Gets my chain nice and sparkly.
Andy Currie Great chain cleaner. I don't use anything else.
Mr Searle Great cleaner.
Cook The best degreaser I've found!
Mr Warner Fantastic stuff. Removed my cassette, soaked it in some of this before brushing off and it came out gleaming. Also used it neat in a chain bath and again worked brilliantly.
Hans This is fanatastic stuff! I recall mention of it somewhere being an extremely effective degreaser and suitable for cleaning chains. My chain tends to get very dirty very quickly, as I ride along a waterfront, so the chains gets fairly muddy and covered in everything from grass to sand. Cleaning the chain was always a huge chore, and utterly dissatisfying as the chain never became really clean. I used some off-the-shelf degreasers from Homebase which were only good at removing the worst of the grime, but never reaching deep enough into the links to properly clean them - I could always hear some crunching noise of caught sand or something else. With Fenwicks, the experience was really different. I soaked the chain in the liquid pure for about 10 minutes, and then agitated it in a closed container for almost 10 minutes. After a good rinse, my chain was in an almost-new state, and the links perfectly clean. I quickly covered them in WD-40 to prevent water from sitting in, and then went about drying and replace the WD-40 with some proper chain oil. Really great! For the cleaning the bike it works fantastically as well, and - no joke - it works as a good oil/fat based stain remover. I've used it on my carpet and on some cloths to good effect - disclaimer, I did experience some slight discolouration, but very minor.
Mr Armstrong Hadn't used this before and really impressed. Used neat on the chain and cassette and got a filthy drive train clean and shiny. Very impressed and would buy again.
Pacla Very good indeed, by far the best drivetrain cleaning product I've used.
Brian Trousers The best product of its type I have used. Brings the chain up sparkly and new when used with the Park Tools chain bath. Use diluted generally on the rest of the bike in a similar way to Muc-Off.
Mr Mcbrine Great for degreasing chains and also cleans rest of bike when diluted
Mr Screen Used this for years. Neat for chains, sprockets etc and diluted in spray bottle for general cleaning. Great product.
Mr Naisbitt The best bike cleaner on the market in my opinion. Used neat in a chain scrubber or diluted for general cleaning it gives great results in no time at all. Good value for your money as well
Ndave First time using this and it is Great stuff, really works well compared to previous other aerosol makes used.
Mr bayliss I love the product, have used it for years but never found a 5ltr bottle untill I came to merlin cycles. Great product and great delivery, the order was despatched on monday and arrived the next day. Very happy with the product and merlin cycles.
Matthew Twigger Works superbly well. Have only used non-diluted so far but, in conjunction with a Park Tools chain bath, got everything sparkly clean!
Mr Jack Excellent product. Use it diluted for cleaning and neat for complete degreasing. Have found it to be excellent on all parts of the bike. No worries about damage to the paint work etc. No sticky residue left unlike other well known products I have used
Dr Murray Excellent product. Cleans the chain real good
Mr Kucuk-kose I use this in a Park Tools chain bath. It does remove the majority of gunk, however, after using the chain bath a bit of scrubbing and elbow grease is required to ensure that the chain is squeaky clean.
Alex Masidlover Cleaned up old bike parts very effectively.
Mr Cornick Really really good product. Cleans & degreasers like magic.
Cops This stuff is great - either dilute for genearal cleaning duties or use as concentrate on chains etc. Fast delivery again!
Mr Clark Love this stuff. I just use a brush to get the stuff on my chain and gears then rinse it off after a couple of minutes, with water. Clean as a whistle. Not used it diluted yet for the rest of the bike, but I am going to soon.
Mr Sargeant I only use this for cleaning, it does everything I need and lasts for ever!
Dave B Good value and cleans the chain as good as any other more expensive fluid.
Mr Ellis Environmentally friendly and does the job perfectly. Brilliant!
Mr Harries Great product, use neat as chain degreaser and dilute for general bike cleaning.
Matt Good quality powerful degreaser. Works well as cleaner at 10-1 and lasts ages.
Mr Spouge Top product! Cleans muddy MTB and chain set with ease! Wouldn't be without it.
Mr leather Excellent stuff- use neat in a chain bath for sparkly chain, or dilute as directed for very a very effective overall bike cleaner. Carbon friendly and eco friendly too.
Mr roots Great product, does what it says on the bottle and excellent value for money as its concentrated so this 1 litre bottle makes 10 litres of cleaner.
Mr T It calls itself a Bike Cleaner and low and behold it cleans bikes - well.
Ms Brunt Amazing cleaning power!

Mr McCombie Excellent degreaser, price and service.
Mr Lewis Excellent multi-purpose product
Mr Short Great suff, does exactly what it's supposed to do!

Mr dore Excellent service as usual, i always check with merlin first. Thanks again
Tim Storr Only used once but seems excellent. Only needed a small amount to bring the rear cassette up like new. Will dilute to use as a general frame/wheel cleaner.
Jon Blunn This is the best cleaning fluid as it is concentrated so goes much further than a squirty bottle. Also used concentrated really cleans chains!
Mr Leatherland Unbeatable value bike cleaner. Use neat to degrease chain etc. or dilute and use it like Muc-off. The best bike cleaner.
P Hurst Works really well for cleaning chain and chainset although you do need to scrub with toothbrush if very dirty
Mr Harries Excellent stuff! Use neat as degreaser on mucky chains and dilute for other parts.
Jon Clements Second time I've ordered this. I use it neat on the chain with a chain cleaning device and dilute it down to give the whole bike a wash. Highly recommended.
Mr HINDMARCH This cleaner when diluted to whatever strength you require, is first class. It beats the 'MUC OFF' product by a mile, and works out a lot cheaper. Highly recommend it. It's gereat for alloy car wheels as well.
Mr hawkins Great cleaner that does it all; dilute for using all over the bike (1/20 is fine) or use neater for degreasing (1/2). I can confirm that you can use on discs and pads with no problems.
Mr Netherwood Seems to work much better than other chain degreasers I have used. Good price, good service.
Steve in Devon Makes up to 10 litres of bike cleaner when diluted which easily stands up to similar products for a fraction of the price. A bottle of this will last me approx 2 years and we have 8 bikes in the stable! Absolute bargain
Mr Fletcher Have been using this stuff for years, does what it says and is good value for money.
Mr Sargeant Been using it for 3 years and always does the job, either diluted for a wash or neat on the greasy stuff.
Mr Fruitbat Use neat in chain cleaner. Dilute 10:1 for general cleaning. Economical, smells nice. Can also be used to clean conservatories and othe PVCu stuff.
Mr Robertson This is the best cleaning liquid on the market. Delivered quickly and as described.
Mr Kendall Does what it should do. 1 litre dilutes down to last ages.
Mr harper This stuff is great much kinder on the bike than muck off. Dilute down to make 11litres in total and spray it every where. Makes cleaning far easier.
Mr hanson fantastic product, excellent as a bike cleaner when diluted & good as a degreaser when used neat.
