More efficient way to clean gears?

Maybe a quicker way, I saw on YouTube to clean carburetor parts a guy put Velcro on the lid of a jar put the parts in the jar added carb cleaner stuff (whatever flavor is your favorite) put the lid back on the jar and attached it to an orbital sander ran it for a while then presto chango the carb parts were clean.

Been saving salsa jars to try it out but have not yet done so. Seems like something that might work.

MEK had always been my go to solvent until I lost my free source.

Thank you all for the suggestions. This is very helpful information. Next time I’ll try toluene and/or letting the gears bathe overnight.


Well that does sound like a more fun solution! I’ll need to think about more use cases for something like that than a winch cleaning every 1-2 years.



That’s what the manual says. Specifically “they must be completely overhauled, cleaned and lubricated at least every 12 months.” That’s probably overkill, although there is a significant amount of dirt in the mineral sprits by the time I’m done.


Yes, I use Harken or Lewmar grease. It’s not hardened, but it doesn’t just come off without some amount of wiping with a paper towel. A longer soak might help make that easier. Good point that I could probably leave some inside the teeth and it wouldn’t be the end of the world. I just wouldn’t want to leave the same grease in a spot repeatedly and have it harden and gather dirt.
Harken grease is know to oxidize, dry, and harden faster than Lewmar (I ran ASTM tests). Superlube Sythetic Grease is also excelent that way.

Gasoline would be a good substitute....cheaper than mineral spirits, but you would have to use it outdoors. Early on during my Navy days, one of the senior petty officers told me to get some "solvent" from the wheel well of a P-2 aircraft. Greenhorn that I was, I spent 30 minutes looking in the wheel well with no joy. Had to go back & tell him that I couldn't find the "solvent". He took me out to the plane & climbed up the wheel to show me a valve, that attached to a fuel tank line, that accessed all the "solvent" that one could possibly need. :facepalm: Over the course of six years, no one ever mentioned using Avgas to clean parts, it was always referred to as "solvent!"

I’ve heard of using diesel too. The “odorless” mineral spirits are not as pungent though.

Just to clarify: Are you suggesting that SuperLube PTFE grease would be a good substitute for the Lewmar grease for maintaining their winches?

As @dlochner stated... MEK and MEKP are not the same

MEK is

MEK is just one more carbon than acetone and is a decent solvent for slighly polar organic materials.

and MEKP is ...

...and MEKP is a polar organic peroxide... (a.k.a. bad stuff). The oxygen-oxygen bond in the middle of the molecule is easily cleaved and when broken, creates two free radicals. Free radicals are highly reactive and will take an electron from just about any molecule with a double bond. You also have a free radical on a hydrocarbon that also has several attached oxygen atoms. The rate of a combustion reaction is often limited by how fast the oxygen atoms can find the hydrocarbon... when they are chemically bound... they can find each other VERY FAST!:yikes:

I have not tried this on parts but nothing works better to get grease off of hands than laundry detergent. Chemists, please weigh in on this theory

Ultrasonic parts cleaners are supposed to be pretty amazing as well
Find a youtube on how micelles work. Soap and detergents have a really cool mechanism for how they clean your skin.

So far I haven't found anything better, cheaper, or more convenient than diesel. I have a variety of tools, from dental picks, small screw drivers, brass wire brushes, and tooth brushes that work well for this project..
Doing winches carefully by hand is something I enjoy doing as it gives me an opportunity to see and check each piece for damage ow wear, before they break.
Some Crosby, Stills & Nash, Dr Hook, Moody Blues or Byrds tunes help make the job more fun.

Two different things. MEK and cardboard ( or other fuels) will not auto ignite through a reaction.

I think I might have just passed the decade mark. I'm pretty disappointed, I'd hoped ONE of you would come up with a better method, or just one I haven't tried yet. I am thinking about my gas powered 2500 psi pressure washer that will etch concrete and some simple green, here someone "hold my beer".

Dont forget to get a couple more hands to catch the flying parts!

Don't get the Simple Green on your ports. It will make them cloudy.

Soak the parts over night. Time is your friend here. The longer the soak, the easier it is to remove the grease.

Not having seen a picture of what your gears look like and the amount of grease you are trying to clean off. Maybe just maybe, like others are eluding to is you are using far to much grease of any kind.
I speak from experience here with my thru hull seacocks. One year I used way much grease during my spring commissioning and actually cause the head thru hull to cease up in a half open position. There was no way it was going to move in either direction all season long. It finally took a heat gun to apply heat to it to melt the grease free as I watched it drip out on the ground.
Just my opinion, try not to be lulled into more is better.

@thinwater Same question here: Is Superlube Synthetic Grease a good substitute for Lewmar grease or not a good substitute? The trailing statement "Superlube Sythetic Grease is also excelent that way" leaves me questioning if it is "excellent that way" means that it hardens or an "excellent that way" as a substitute.

Organic chemistry; brings back nightmares :yikes:. Happy that you Chem E's deal with that stuff for the rest of us!:p
At the end of the semester I went to my Organic Chem Prof and asked about my grade. He looked at a list of students and grades and asked what my name was again. He then went to the list, found my name and drew a line under it. Those below the line failed. I changed majors.
