Does anything dissolve paint thinner
I use paint thinner and an old tooth brush to clean my bike chain.
Is there anything I can spray on the chain to dissolve the thinner or do I have to manually rub it off with a rag? I am open to recommendations to anyone who actually uses one of those chain cleaners. Thanks, Andy |

Cabernet is good Bordeaux as well. But I think that he has the idea that when he cuts the grease he needs to wash the solvent off in some manner with all of that sludge. And the answer is a very strong soap and hot water. Use rubber gloves since most dishwashing detergent is designed to cut all oil and will take all of the oils out of your skin and fingernails. In automotive supply stores they have an extremely strong detergent that is in a blue bottle. Rather than using paint thinner on a chain, you put about a cup full of that stuff in a 4 sup measuring cup and put your dirty chain in there and let it sit for 15 minutes and then wash it off with a hose into the gutter. DO NOT let that stuff touch your hands since it makes dishwashing detergent look like spring water. |

Believe him. -- Jay Beattie. Solvents for solvents: When I was an undergrad intern at an electronics research facility, we (I) had to ultra-clean items for use in vacuum. Leave bits of oil on them, and they "out-gas," degrading the vacuum, or so I was told. IIRC, the sequence was: 1) ?Alkanox? Alkaline cleaner - seemed like Comet -- & water, ultrasonic for xx minutes. Then 2) Chlorinated solvent (TCE??), ultrasonic for xx minutes. Then 3) Acetone, ultrasonic, then 4) Methanol, ultrasonic. All under the vent hood, of course. Drop something in between steps, you start all over. So yes, solvents for solvents, but you probably don't need to ultra-clean your chain, and I suspect you'd never succeed anyway. My current chain-cleaning ritual: 1) Soak in (fairly dirty) mineral spirits overnight, in capped 2 liter soda bottle. This thins the grease/muck. 2) Put chain in the heated ultrasonic cleaner (I splurged last year) with a pretty concentrated mix of Simple Green and water, for something like 10 minutes. This seems to get out the grit; I don't have the nerve to put flammable solvents in the heated cheapo ultrasonic. 3) Rinse with fresh warm water in another 2 liter bottle, shake vigorously. Maybe change water and rinse again. 4) Blow dry with jet from compressor (this year's splurge), then hang to dry overnight. Elapsed time is pretty long, but actual work time is under 10 minutes, perhaps under 5. If I need to add an obsessive step, it would be to rinse with clear water in the ultrasonic, but draining/refilling the ultrasonic would take actual time. Got a gravel bike last spring that I --gasp-- ride on gravel, and the chain gets pretty dirty pretty fast, so I need to clean more often than I did in my pure-roadie days. Mark J. |

I am a retired chemist with over 35 years of experience. And I had to dissolve many substances in order to run analyses and clean equipment. You can say all you want, but IPA NEVER HAS and NEVER WILL dissolve oils and greases. Andy Well, I guess I'll just have to try it. Found a tiny 50 ml beaker and added 10 ml of 91% IPA. I then dumped in a dime size blob of whatever greases I could find around the house. I then stirred the solution lightly (no stirring rod). If the grease dissolved into the IPA, then IPA can be used as a solvent to clean it. If it remained mostly intact, it's insoluble. After that, I found a white pine board, and ground a dime size spot of grease into the board with my thumb. I then wiped it clean with a paper towel. In all cases, there was some residue embedded in the wood. I then used a different paper towel to try and clean off the residue. If IPA was able to clean the embedded grease, then I would consider IPA a solvent. Soluble? Pine board Lithium white grease. Yes Yes 10-30wt engine oil. No Somewhat WD-40 No No 3-in-one oil. Yes Yes Unlabelled gear lube. Somewhat Yes Moly disulfide grease. No No Al2O3 thermal goo. Yes Most but not all LPS3 (wax film lube). Yes Yes Mystery black grease gun. Yes Most but not all The results showing "most but not all" seem to have left a solid particle residue in the grain of the wood which I could not remove with IPA and scrubbing. The greasy carrier was removed, but not the solid particles. Sorry, no photos because I didn't want to get grease all over my smartphone or camera. Maybe if I can dig up an accomplice, I can make a YouTube video and become famous. If I wanted to do it correctly, I would use a viscosity tester (tilting glass slide). Or, I could stir more vigorously, and use a centrifuge to see if the grease and IPA could be separated. If I feel ambitious or someone has a better idea, I can easily re-run the tests and add a few more greases that are more likely to be found on a bicycle chain. I can't conclude anything either way with what I'll readily admit are two rather lousy tests. Offhand, it would seem that some greases and oils will not dissolve in IPA, while others will to varying degrees. Meanwhile, I'll burn some time pondering all the web sites recommending IPA for grease and stain removal: https://www.google.com/search?q=alcohol+grease+removal Drivel: One thing that 91% IPA is good for is removing the sticky depolymerized rubber goo (paint) from the surface of computer keyboards, mice, toys, etc. (Thank you Logitech). I've had to recycle or toss far too much of this stuff simply because I couldn't remove the sticky goo. IPA works, but does require some heavy duty scrubbing. What's left is bare plastic, but that's better than dealing with the sticky rubberish mess. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
