Numbers can be compared and such tests are allegedly reproducible. What I did was do what I could (without cleaning up my messy workbench). Your comment about few more greases that are more likely to be found on a bicycle chain. got me very interested. I recently had my local bike shop install a new chain. I did not use any chain lubricant. Did you feel any grease on the chain? New chains, out of the box, are delivered covered with the factory grease and in a plastic bag to prevent the grease from making a mess. The grease is quite good quality and is distributed properly around the pin and bushing, which are the important bearing surfaces. If the LBS (local bike shop) "cleaned" the chain with solvent, and failed to re-lubricate it with something (grease, wax, dry lube, PTFE, magic miracle lube, etc) then the chain will wear quickly. However, quickly is measure in miles or km. It sounds like you didn't ride very far or much, which is far less than it takes to ruin a chain. I suggest you go back to your LBS and ask them what they did and what they recommend you now do. Within less than a week, my chain had a coating of grease. So I thought, where did that grease come from? Magic. The factory grease is usually all over the chain. However, if the LBS wiped off the grease from side plates, it might look like there was no grease, but there might have been plenty inside the chain parts. A little warm sun and some riding, would eventually migrate this grease to other parts of the chain. Otherwise, it has to be magic. I understand where the dirt comes from. I remembered that I pretty much always ride at least once a week through water puddles or rain. Water + non-lubricated bicycle chain = rust So you see any rust on the chain? If not, the chain was coated with some kind of chain lube or protective coating (LPS 3 wax). So I think that water + rain = grease. Rain is water, so adding additional water does not produce anything new. Well, maybe if it's raining oil. Do you live under an oil well or something similar? A storm or hurricane that just over-ran an oil field or oil spill? For a while I used 70% isopropyl alcohol to pull out the water when I wanted to pull the water out of something so it would dry quickly. 70% IPA is formulated specifically for its antiseptic qualities. Most bacteria are killed by alcohol by denaturing proteins. A little water makes the process more efficient. 91% IPA is better for cleaning. Note that both concentrations are hygroscopic and will absorb water from the air. Keep the container closed. I later learned that 90% IPA was much more efficient. For cleaning 91% is best. For medicinal purposes, 70% works better. What do you think? Now that you've removed some of the grease with alcohol, you should do something about re-lubricating the chain. I don't ride enough to require regular chain lubrication, so I'll keep my magic chain elixir formula to myself. However, I'm sure that there are plenty of others in this newsgroup who will gladly offer their experience and methodology. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I understand the concept, but I can’t imagine the collapsing bubbles imparting any substantial amount of physical scrubbing action. The cavitation produced by the collapsing bubbles is capable of pitting soft metals. However, there are no soft metals on a bicycle chain, so I guess it's safe. Ultrasonic Cleaning https://en.wikipedia.org/wiki/Ultrasonic_cleaning Ultrasonic cleaning uses cavitation bubbles induced by high frequency pressure (sound) waves to agitate a liquid. The agitation produces high forces on contaminants adhering to substrates like metals, plastics, glass, rubber, and ceramics. This action also penetrates blind holes, cracks, and recesses. The intention is to thoroughly remove all traces of contamination tightly adhering or embedded onto solid surfaces. Seems (to me) similar to the bubbling action of vinegar and baking soda. However, there's one important difference. The ultrasonic cleaner delivers quite a bit of energy to force the soap solution to produce bubbles, while the vinegar and soda mix has much less chemical energy. At some point during the chemical reaction, the vinegar and soda mix might approach the energy level of the ultrasonic cleaner, but for very long. Maybe the expanding bubbles might force the soap solution deeper into parts, but at that dilution ratio, and considering that you’re supposed to mix it together in a spray bottle BEFORE using it, I have low hopes. If I had to come up with a homemade EZ-Clean solution, I would use dish soap and boiling water. I currently don't have an ultrasonic cleaner. However, I do have a two stage vacuum pump and chamber (modified pressure cooker). I use it mostly for getting the bubbles out of resin molds and epoxy potting compound. However, when the chamber is filled with water, I can make it cold boil by simply reducing the atmospheric pressure. I have no idea what will happen, but a little soap in the water might be a good way to clean things without the risk of melting something from hot water at atmospheric pressure.

I could use it to clean my chain, but I do not feel like taking the chain off. :-) Andy |
