Yet another thread on chain cleaning
Sorry to flog a dead horse and everything but I have some questions that I
haven't been able to find answers to in the archives and FAQ, so here goes... [It seems this has turned into a bit of a rant now so feel free to scroll to the bottom for the actual question I'm asking...] I cleaned the chain on my new bike (Dawes touring bike, exclusively on-road use in pretty clean conditions and so far rarely in rain) as thoroughly as I could a week ago. It had 750mi on it at the time and I had the bike in for its complimentary service at about 400mi. It came back liberally lubricated and soon became a black mess (no doubt they just lubed whatever they use on to the dirty chain, great). Before that I was managing to keep it pretty clean with regular wiping down and I lubricated it once with the PTFE lube I bought under recommendation from the shop. It was getting pretty squeaky when shifting the rear derailer, I assume from lack of lube, but I wanted to leave it until the service to let them deal with it as I figured they know more than I do. Anyway, after it became a black mess I knew it was time to sort it out properly. I wiped it down thoroughly several times to try and keep it clean then finally attacked it properly at 750mi on. I wiped it down thoroughly with an old sock, scrubbed it with soapy water and a toothbrush (I think this was pretty redundant because it didn't have loads of mud or dirt on it, so it didn't seem to make much difference), dried it with the sock, let it stand for about 10-20mins, sprayed Halfords brand degreaser aeresol on it ("Rapid Air-Drying Formula", how useful -- it seems to dry instantaneously, but at least the blast of the aeresol spray seems to work quite well at cleaning pretty much instantly) and wiped with the sock vigorously. Several cycles of the entire chain. It was still feeling pretty nasty when flexing it laterally, like it had grit still in there, though externally it was looking pretty good. I decided that this was as good as I was going to get it and then applied the PTFE lube, using the narrow spray tube to apply a stream of penetrating, foamy, lubricant. I backpedalled the cranks for a little bit and wiped off the excess. I also wiped off the chain several times in the next few days. I think the main pitfall was that I didn't manage to clean it as thoroughly as I would have liked. It didn't really feel "fresh" inside when I played with it. Also, I didn't rinse off the degreaser, so although on the surface it dries pretty quick there may have been some left inside the chain. I think the effect of this would have been pretty limited though. So anyway, now it's a week later and I am 830mi on. I got home after a bit of light rain and got a bit carried away. First I wiped the frame dry, then sprayed WD40 into all the unused rack mountings and other frame holes, wiped the excess off and wiped the frame down with the WD40'd rag, then applied PTFE lube to all the cable housing entry points, then to all the pivot points on the derailers. Then I discovered how to use the PowerLink on my Sachs/SRAM chain and took it off. It didn't feel as bad as right after I cleaned it. I think it's because part of the dodgy feeling I had when flexing it may have been due to the liquid inside... or maybe the lubricant flushed some of the crap out to be picked up on subsequent wipe-downs? Anyhow, I wiped it down seveal more times, then sprayed it with the degreaser aeresol *liberally* and continued wiping it down. Unfortunately it didn't seem to make all that much difference and I felt like I was wasting time and degreaser. It still felt a little bit gritty inside. I found a wide-neck 1L lemonade bottle and threw the chain in there in preperation to soak it in something. (Actually, having another look at it now it doesn't seem so bad. The gritty feeling is completely gone! Just a bit dirty between some links and I can feel that it's not *completely* clean inside the rollers.) ======================== End semi-irrelevant rant, begin actual question about chain cleaning... ======================== I had a rummage around the garage and found: Mineralised Methylated Spirit (Funky purple colour!) White Spirit 70% Isopropyl Alcohol Which one of these would be the best to pour into the bottle and shake occasionally to get the chain clean? I plan to leave it on my desk for a few hours and give it a vigorous shake every now and then. Other things I can think of to use a Fairy dishwashing liquid (can't see this working too well) Dishwashing-machine powder (I'm wary of this stuff ever since it ate pits into the bottom of a pan when left overnight in the sink) coca cola (with all this whining about how it's so acidic, I figure it might do some good. probably too much sugar and not enough chemicals capable of breaking down the grease though.) Are there any precautions? Is it posible to "over-do it" with any of these chemicals? (Aside from the dishwashing-machine powder) I plan on soaking it for a couple of hours with frequent agitation, then pouring out whatever I'm using into a jar for reuse, and filling the bottle with water and shaking vigorously for a while, maybe changing the water a few times to make sure I clean out all of the cleaning chemicals. Then drying it with a rag and leaving it out to dry overnight before putting it back on the bike and aplying PTFE lubricant with a narrow tube, letting it work its way in, then wiping down with a rag. How does that sound? Thanks a lot, Dani |

After-thought:
If I use something like White Spirit I can just do a few rinses with that then let the chain dry, as opposed to rinsing it with water. |

I favor taking the chain off every 500 miles or so and soaking it for a few hours in a solution of water and Simple Green, a citrus-based nontoxic degreaser/cleaner. I shake the container once or twice, or not at all, the time seems to be more important than the agitation. I then take a toothbrush and using the leftover solution give the thing a quick scrub in the work basin. Rinse with hot water, dry with a rag, hang it up for a couple of hours or overnight, then put it on the bike and lube. It's probably overkill but I like having everything perfectly clean rather than doing a partial job. I only do this when I have a chance to give the bike a full cleaning where I get the gunk off the chainrings, cogs and pulleys. If they are still dirty they soil the chain quickly; in that case I just clean the chain as best I can on the bike with new lube and a rag. |

If it needs the toothbrush, I figure, then there's still
grit inside. With repeated immersion, one can see when the grit stops coming out. I can't think of any other way to know that. After seeing that, I can't imagine that anything else works.

I clean my chain when I think it's full of crud, or when I'm cleaning the whole bike. Other than that, I load it up with chain lube every few rides; it never squeaks, and my drivetrain lasts as long as anybody else's. At least, this has been the case with my badly abused mountain bike. I haven't had road bikes long enough to know. I've got better things to do than clean my chain every day. Things such as offending people on newsfroups... Thanks a lot, Dani -- Rick Onanian |

may have said: I've got better things to do than clean my chain every day. Things such as offending people on newsfroups... Some people may have have... - an inside parking place in which they must have a clean chain or risk enraging The Gods, or - time to engage in such things, and the willingsness or personally imposed imperative to do so, or - a cleanliness fetish, or - a bike that they take pride in, to the point of wanting to keep it in spanking clean condition all the time, or - a complete lack of ability to ignore small glitches, or - nothing with a higher priority that would keep them from cleaning their chain at that time[1], or - some other reason to want to do this sort of thing. And, of course, there are folks who do it because the people with the chain fetishes told them it was a good idea...and the list still grows. I clean mine as I acquire used bikes, as I notice them getting really cruddy, and as time permits. The last time that I actually *wore out* a chain was in (if I recall correctly) 1971. On the other hand, the last time I *replaced* a chain was a couple of months ago, at aquisition of a used bike that had pretty clearly been ridden hard and put up wet....literally. [1] depending upon the bike owner involved, this could include watching The Simpsons on TV. -- My email address is antispammed; pull WEEDS if replying via e-mail. Yes, I have a killfile.

It doesn't take an hour to clean the chain. I have two chains either of which at any given time is "in cleaning/lubing". Cleaning just means shaking the chain in solvent which is then filtered and used again with the same chain. Lubing means leaving the chain in bath of oil for a while and then hanging it up for the excess to drain off, following which the chain is wiped with a cloth and is then ready for use. The whole process is spread over a period several days depending on when I am in the shed and in the mood for a couple of minutes "work". Having said this, I don't know how clean my chains really are (inside) after all this and whether they will last longer but I like putting a "fresh" chain on every week or so! Phileas |

Filtering is unnecessary, anything that a filter will catch will settle out quickly. I've used the same solvent for years, doing more than a dozen cleanings/year with the same quart or so of paint thinner. Lubing means leaving the chain in bath of oil for a while and then hanging it up for the excess to drain off, following which the chain is wiped with a cloth and is then ready for use. I don't see where soaking a chain in lube does anything that simply oiling a chain on the bike does. Sounds messy. Having said this, I don't know how clean my chains really are (inside) after all this and whether they will last longer but I like putting a "fresh" chain on every week or so! I find that if I flex a chain after a solvent shake, if there's any grit left on the pins you can easily feel it once most of the lube is washed out. |

A couple of years it's not, but you are not the only such person. I get cheaper chains (more like $10 in your money) and more awkwardly obtained cassettes, so I follow the 12 1/16" recommendation and aim to get three or four chains to a cassette, but life's too short to do any more than oil them when they squeak. -- David Damerell Kill the tomato! |

Are there any precautions? Is it posible to "over-do it" with any of these chemicals? (Aside from the dishwashing-machine powder) I plan on soaking it for a couple of hours with frequent agitation, then pouring out whatever I'm using into a jar for reuse, and filling the bottle with water and shaking vigorously for a while, maybe changing the water a few times to make sure I clean out all of the cleaning chemicals. Then drying it with a rag and leaving it out to dry overnight before putting it back on the bike and aplying PTFE lubricant with a narrow tube, letting it work its way in, then wiping down with a rag. How does that sound? Thanks a lot, Dani I do not believe in using volatile solvents unless it is absolutely necessary. Detergents and citrus cleaners are inexpensive, work very well for cleaning chains and are easier on you and the environment. I wanted to see if my chain cleaning ritual actually cleaned the chain deep down around the pins, so here is what I did: I removed the dirty chain then re-installed the quick link and held it in place with a twisted piece of soft wire. This is to prevent the link from opening with no tension on the chain. Then I did my usual cleansing ritual: put chain in bottle, add hot water plus Simple Green, cap, shake, hold for 15 minutes or longer, empty, repeat two or three times until the liquid does not change color, rinse with hot water, and dry with a hot air gun (a hair dryer works, but is slower.) Then I opened the quick link to see if it was clean inside. It was. The pins were bright and shiny as were the insides of the side plates. The exposed ends of the inner links and the drawn bushings for the pins were also clean inside and out. So, I'm convinced that my easy, no volatile solvent method is fast and effective. Much of the Simple Green can be re-used if it is saved. Just allow the gunk to settle and decant the clean cleaner. For lube, I've been using 20W 50 motor oil. It works very well and lasts for hundreds of miles (probably much longer although I clean the chain every 200 to 500 hundred miles so I don't know.) The motor oil is messy. No matter how many times I wipe the chain after applying the oil, I see a fine mist of oil on my back rim, especially for the first 50 miles or so. Also, the oil attracts dirt. I wipe the chain frequently, but I do not add more lube between cleanings. Under this method, the chain never, never squeaks and always shifts smoothly. There is no measurable chain wear after slightly less then 2K miles on the chain. I noticed that the lube that comes on new SRAM chains feels thick and sticky. I also notice that it lasts forever and it attracts less dirt then the motor oil. I found this in a head to head comparison as my wife has the new SRAM chain and we ride together. Although it seems counterintuitive, it has led me to try a thicker, sticker lube; chain saw bar oil. I have not used it enough to form an opinion yet. Sheldon Brown suggested the chain-in-the-bottle cleaning method I use. Jobst Brandt suggested the lubing method. Steve Shapiro |
