Hi, how You can get the oxidized aluminium shiny again? I ruined my cylinder head with oven cleaner...

Oven cleaner probably contains caustic soda which will attack the aluminum removing and pitting the surface of the metal. It won't be shiny after being treated like that!

I have not tried carbs mainly because I have not had the need to do so. This crap gasoline we are forced to use leaves some stubborn deposits and the deep recesses are hard to get to. If the carb is completely disassembled I think it would work, but I would use a new batch of ethylene glycol.

Crock pot works well as it just needs to simmer and the lid keeps the brew from boiling off (evaporating). Ron

I have only used the old, original, green ethylene glycol antifreeze. Apparently people using some of the other color antifreeze have had a darkening of aluminum castings (such as carbs) so pay attention to what you are using. Thanks for watching. Please Subscribe!

Sorry, I do not know... I have not tried it. Ron

Euro Bum it should still work

Yes it works it dissolves oil but will proably take longer. People use PG for vaping aswell.

This is not going to work for heavy rust. There are other processes better for that. In any case you'll need to take it all apart.

Haven't tried it. Internal loosened deposits would possibly remain internal and plug things. Often times seals and o-rings need to be replaced so disassembly is still required. Ultrasonic cleaners work well for injector cleaning (disassembled).

Ha ha...apparently you had brain damage before you started brushing your teeth with it. :)

Needs to be the old original green ethylene glycol antifreeze and if it is very old, it may not work very well. I have always started off with new stuff.

Thanks again.

I do not remember. Google "Dremel carbide drum sander" and see what comes up. I may have found them at Tower Hobbies years ago... or Micro Fasteners. Now there are what is called "structured tooth" carbide burrs (fairly expensive) that are really aggressive and somewhat dangerous for the fingers as they can grab and jump.

In my experience the simmering action is of more benefit that the ultrasonic cleaner. Once the part is rinsed clean with soap and water, if any residue remains the ultrasonic may be of further benefit.

@@RonaldWalters2010 Thanks Ron, great advice!

This was never intended to demonstrate preparing a metal surface for painting. It removes/loosens caked-on material, grease, carbon and such. Glycol and water has a slippery feel. If you were doing this to remove grease and oil, then that oily film will still be on the surface of the water and will end up on the part when it is removed. Rinsing it with soap and water should get rid of the remaining film. Preparing the metal for paint could consist of using a wire brush, emery paper, steel wool with elbow grease followed by paint thinner. Hope that helps. Thanks for watching Please subscribe.

@@RonaldWalters2010 awesome thank you!

+Bike Man Dan You really need to simmer the parts on a hot plate and ultrasonic cleaners don't get that hot... at least mine does not. The glycol really cleans well but can leave an oily film as the parts are removed. The ultrasonic cleaner with a little soap in the water degreases the parts... or just try washing in hot soapy water and then rinse with plain water.

I haven't had it darken the parts.

Doesn't seem to. But don't believe me... go ahead and try it. Remember some of the antifreeze sold now is already diluted for people who are too lazy to do it themselves.

Usually a dirty (greased) chain (as in drive chain or bicycle chain) only needs to be soaked in diesel oil or kerosene to loosen and remove the caked on debris.

I have no idea... Never cleaned one.

Cold probably won't work very well. It needs to simmer. Generally left over night or check it every few hours until everything is clean.

I live in an apartment building. How bad are the fumes?

Not bad enough to piss off your neighbors but I would not breath it. Use the stove exhaust fan or a hot plate out on a balcony.

I'll go out and buy a hot plate.

Yes, for mildly dirty items. Not as good, and certainly not as fast, as simmering it on a hot plate IMHO.

Ronald Walters The reason I'm asking is that I can get a hold of a cheap ultrasonic cleaner which can heat up the chosen 'liquid' up to 80°C, which in theory should be similar only with the added vibration. I will give it a try anyway as I have 5 motorcycle carb racks (20 carbs in total) which I don't fancy tackling individually.

80 deg C is only 176 deg F which is well below boiling which is 212 deg F. Might want to try one first. Also note: I have never had any discoloration using the old, original, green ethylene glycol antifreeze. Apparently people using some of the other color antifreeze have had a darkening of aluminum castings (such as carbs) so pay attention to what you are using.

Ethylene Glycol is antifreeze. Propylene Glycol is also antifreeze... but I have not tried it. I know Ethylene glycol works.

As you can see in my video, I had no discoloration of anything using this process with ethylene glycol. On a few places (such as the OS muffler) where the original anodizing was scratched or the aluminum had become corroded, those areas will remain discolored... but the cleaning process itself did not discolor those areas. Note: Some viewers have had the mistaken opinion that all antifreeze is the same (i.e. ethylene glycol) however some is propylene glycol and some may contain other additives. I have only used ethylene glycol based antifreeze and I HAVE NOT tested this process using propylene glycol. Long story short... I have no idea why your engine changed color, nor would I know how to undo whatever changed the color. Sorry. Thanks for watching. Please Subscribe. Ron

@@RonaldWalters2010 thank you for your comments and suggestion. What is you opinion on high temp spray paints?? Do you think it will last on these engines?

I certainly would not paint the engine with anything. A coating of paint would most likely interfere with the proper cooling of the engine and would make the accumulation of burnt on castor oil even worse. Then, when it comes time to clean the engine again... ethylene glycol is a paint thinner and it would remove the paint and the dissolved paint would mess up the glycol at the same time.

@@RonaldWalters2010 thanks you for your valuable suggestion.. i never thought of it!! Much much appreciated..

I am not familiar with glycerol. I don't do this much anymore. If I can find it I may try it next time (if I remember). Although ethylene glycol is technically flammable (vapors) even when dissolved in water, with a flash point of 260/280 degF (closed cup/open cup) it is unlikely it will flash when simmering in the pan on a hot plate cleaning these parts. Thanks for watching.

Quite a few wives have killed their husbands with EG, might want to pour your own drinks!

Pets too. Many dogs are poisoned by EG spills left by lazy owners.

Hence... The "ex-wife" part. :-)

Good one. Funny!

There is only one ethylene glycol but there are many types of anti-freeze.

They come in different colors and flavors. Just see which one tastes best to you. Quote" Lets remove all the warning labels and let nature take its course"
