Does anyone have a recipe for a homemade bicycle degreaser solution? I'd like to make my own degreaser solution instead of buying one. I have read about using lemon juice and various types of alcohols - white spirits, etc.

EDIT: I should have actually explained I was looking for a homemade bicycle degreaser liquid, not just cleaning liquid. I have now edited the title and wording. Sorry for the wrong title.

If what you're looking for is a cheap alternative, here in my country is very common to use diesel or kerosene to clean bike parts. Personally I use diesel, I just pour a small amount in an old plastic cup, and use a brush (the kind normally used for painting) to rub it all over derailleurs, cogsets, bearings, etc.

It is plenty effective for removing even heavy grease. It is smelly and leaves an oily residue that can be easily removed with dish soap. (I prefer the liquid one). I Like to use it because it is effective, and the "residue" seems to be protective against corrosion for a few days. You can use rubber gloves, since diesel won't melt them, but if carefully used barehands, it won't cause much trouble as long as you wash your hands right after the job, which you can do with plain water and hand soap.

On a side note: Liquid dish soap is an amazing grease remover, but it needs scrubbing, so it does not make the job as easy as diesel. It is extremely useful for the rubber parts of the bike, leaves tyres looking really good, and does wonders with the grips: somehow they end up shiny but not slippery, and it's really easy on the paint job, try it!

Diesel has the advantage of being not so flammable as gasoline or kerosene. You can't light up liquid diesel with a spark or a match, but with kerosene or gasoline it's easy, thus my choice for diesel.

Another reason to prefer diesel over gasoline or paint solvents, is that it won't damage plastic or rubber parts, as gasoline would do. Some paint solvents may cause long term discoloration of paint (d'uh!) or plastic parts if used frequently. I haven't had these situations with diesel.

Kerosene is more flammable, less viscous and less smelly, but I have never used it for cleaning.

Many years ago, I used to clean with gasoline, but the smell is unbearable after a few minutes, it damages plastic, rubber and paint. It melts some kinds of rubber gloves and causes immediate damage to the skin. For some specific jobs it can be useful though, since it evaporates rather quickly, leaving no residue.

Bottom line: As with all flammable /volatile liquids, they should be used with caution, in open, ventilated environments, and should be stored carefully, properly labeled and out of reach of unsuitable users (children, elderly, etc...).

Gasoline is really really unsafe to use for lots of reasons! ( – WTHarper Jan 31 '13 at 19:18
I used to use Diesel as it's cheep and cleaner than Gasoline. But I stopped some time ago, I find that's it's not really necessary for 99% of cleaning jobs. A small amount of WD40 and some car shampoo get the job done. – alex Feb 1 '13 at 6:12
Any flammable cleaner is not a safe choice. – Paparazzi Aug 14 '14 at 2:00
My bike chain gets really dirty since I commute to work every day - the bio-degradable tosh they sell in the store doesn't work and my neighbour introduced me to the effectiveness of diesel. Cheap and easy! Ironincally, it's illegal for a bike shop to clean with diesel in the country I live, but nothing to stop me doing it at home :) – vikingsteve Aug 14 '14 at 10:11
Commuting in a reasonably clean city should not cause your chain to get too dirty that fast. Consider using a thiner oil or even a dry lube on your chain so dirt doesn´t stick that much to it. You won't have to clean it so frequently. And less dirt and grime stuck on chain's lube means less grinding wear. – Jahaziel Aug 22 '14 at 15:01

I am a industrial chemist and manufacture commercial grade degreasers and other cleaners for a as my occupation... this is what i recommend for a home-made degreaser...

Firstly there are three main parts to a degreaser... they are as follows:

  1. Alkaline booster (to increase the pH to allow the dirt and grease and grime to be effectively removed for faster cleaning)
  2. Solvent (to cut through tough grime and grease as well as extract grime and grease from hard to get areas)
  3. Surfactant (to hold grime and grease in solution to prevent from depositing back on the bikes surface once lifted off by the solvent and the alkaline solution)

(there are also other components in a professional degreaser such as water softeners, hydro-tropes, both anionic and ionic surfactants, specific application solvents etc etc)...

However, that part said, the main thing you will need as mentioned above is the alkaline booster, the solvent and the surfactant...

The main source of these will be from using backing soda as a alkaline booster, methylated spirits (i would use methylated spirits because it is soluble in a water solution) as a solvent and a small amount of dish washing liquid as a surfactant... so an example formulation would be to use the following concentration:

5% dishwashing liquid 50% methylated spirits 5% Sodium Bicarbonate (Baking Soda) 40% Water (H20)

The methylated spirits and the Sodium Bicarbonate will work together to extract and lift the dirt/grime/grease and the dish washing liquid will work as a surfactant to stop it from depositing back down again

The dish washing liquid will also act as a wetting agent and a foam booster...

EDIT ----

Please also note, that the methylated spirits will prevent or close to prevent any foam or the likes forming... if you want foam you will have to substitute the methylated spirits with a mild solvent that is hydrophilic and not oil based (lipophilic)

EDIT ----

I hope this helps and this question isn't too old to not get any readers...

If i have helped please rate my answer up...

Many thanks

I made this mixture, but substituted methylated alcohol with isopropyl rubbing alcohol; this recipe seemed to work better than the degreaser I had purchased, thanks for the tip! – iBorg Jun 10 '14 at 2:12

@JeremyFisk do you wash off your degreaser before applying lube? Would it work the same if I use dishwashing liquid + baking soda + water, and then wash it off with methylated spirits or isopropyl alcohol? – alkar Sep 25 '14 at 22:10
this mixing percentages are by mass or by volume? – Davorin Ruševljan Jan 8 '15 at 15:11
@alkar Yes you should wash it of with water first as the dirt/grime/grease will be sitting in encapsulated little balls on the surface that needs to be rinsed off. Cleaning with methylated spirits or isopropyl alcohol is a good idea as a final clean however is not necessary (however it can make it easier to apply lube etc as it will allow everything to dry more water free and any alcohol residue will evaporate fast meaning pure application of lube is easier) – Jeremy Fisk Jul 14 '15 at 7:40

I use the colourless, odorless liquid that comes out of taps and sometimes (often, where I am) falls from the sky...

Beyond simply using a damp cloth, when I'm doing maintenance, I'll wipe off any grease or oil using WD-40 or Liquid Wrench or Brake Clean (whatever I have on hand for cleaning bolts).

We don't have that brand of dish soap here, but I wouldn't hesitate to use something like that on a bike. For people who are worried about harsh soaps, there's Palmolive, which is well-known for being very gentle.

Hmm, I must look for that odorless liquid..I wonder if we have it here :) Fairy is the UK equivalent of Palmolive. – Bernard Tyers Apr 29 '12 at 18:19
Watch out for the high salt content of washing up liquid. – alex Feb 1 '13 at 6:14

A degreaser needs to contain either a solvent or an emulsifier or both. Deionized water (not tap water) combined with citric acid works pretty well as an emulsifier for slightly greasy stuff (it's used for cleaning electronic components), but by itself is probably no match for, say, a greasy derailer. There are other emulsifiers that are a bit stronger (including plain soap/detergent).

Petroleum solvents, of course, are pretty good at cutting petroleum-based grease, but pure petroleum solvents are environmentally unfriendly and don't do much for removing general grime. Alcohol is not a particularly good solvent for petroleum products and hence not a very good degreaser.

I suspect a lot of modern commercial degreasers now contain an emulsifier plus a "dash" of solvent.

For those of you who still may be looking for a cheap degreaser, search for Virosol. This is the strongest degreaser I've seen. You'd normally buy it from sites selling industrial cleaning chemicals. It's eco-friendly and leaves your bike spotless.

It was less than £10 for 5L delivered (UK). It's concentrated so for general cleaning I dilute it 1:10, for chain etc 1:2. Basically, 5L will last you for ages.

Be careful though, couple of drops can leave ball bearings in the hub clean as well.

Hope this helps someone.

A good recipe for a cheap, simple homemade degreaser is water + borax + washing (laundry) powder, mixed in the ratio 12:4:1. Keep it in a jar as spray bottles can get clogged (but might be worth a try for ease of application).

It works on my bike. Some soaking and/or scrubbing with an old toothbrush is required for stubborn muck and grease, for example: when overhauling headset or BB bearings and it should work for derailleurs too.

I've used sugar (yes, the stuff put in coffee or on cereal) and liquid dish soap as a very effective home-made degreaser for my hands after working on bike or truck but haven't thought to try it on the parts themselves. For the metal bits I usually use WD-40 or Powerblaster and a scrub or toothbrush. I buy the "WD" in 1 gallon containers (liquid form, not "aerosol") and use a plastic 5 gallon pail as a parts washer. After the project is done, I'll pour off the "used" liquid into a smaller container (filtering as necessary) and reuse it for future degreasing projects.

Brake Parts cleaner, as suggested above also works, but it's more toxic and I generally reserve it for things that truly need to be clean, perhaps in preparation for painting, not parts that are going to be re-greased after cleaning. I'd put diesel in the same general category. Very effective, but not as pleasant, or "safe", to work with.

The best degreaser is simply a rag.

Disassemble the parts, rub them briskly with a rag, re-grease/re-oil and re-assemble.

YMMV depending on how far you let things go before servicing.

Solvents are not only bad for the environment (no I am not from Greenpeace) but also bad for your health. Luckily many solvent free solutions are mantioned above. Soap and water, a dry rag and washing up liquid. No need for solvents at all. Have you ever had to wash your dirty black hands after handling the greasy, rusty old chain of and old street bike og after fixing something on your car? Did you use a special hand degreasing fluid? No because soap and water does the trick - washing up fluid if soap is not enough. If the same kind of oily dirt is on your bike, the same kind of washing technique applies.

A friend of mien told me that he is using Coca Cola as a degreaser and rust remover. He leaves overnight the chain in the Cola and after that he washes with water to remove the sugary stuff.

I never tired and I don't even recommend it, but I think this is a cheap feasible solution.

You will spend a lot of time with washing of the cola and waiting to dry your chain. I rather use paint solvents.
