Remove kerosene odor from brass fount

#1

Post by fjfj765 »

Hi,

I am trying to wash the fount of an old kerosene stove before flying with it. I have washed it with several tank fulls of boiling dawn and water. This has reduced, but not removed the kerosene odor.

The stove was probably left with kerosene in it, and it dried out, leaving behind a crust of old kerosene.

I am out of dawn, and cannot get any more.

I cannot get MEK, naphtha, or DNA.

The only things I can use are Chinese dish soaps, which may contain ammonia, and thus I will not be using, IPA, and water.

What to do?

Thanks,

-Arthur Gu

Where are you and your stove?
Do you have limitations on what you can get or do with the stove in your location?

Besides what had already been suggested, you can also try using hydrogen peroxide to remove any traces the 'sulfurous / mercaptan-like' or what's typical of kero odor.
The higher the peroxide concentration, the more effectove it is.

Clorox and other chlorinated bleaches can also get rid of a lot of such odors but they might not be the best stuffs to use inside the stove's fount.

You can get yellow Heet 99% DNA or close many places. Better double, triple check airlines about flying with a liquid fuel stove. Got by with pocket rocket, no fuel in checked luggage to Yellowstone. Bear spray no go. Had a stinky 550 once and windex helped somewhat.

I’m in china already. 75%ipa is what I can find, so I’m soaking the fount in that for the next week.

H2O2 is available, but it’s a strong oxidizer. Will it damage the patina?

Use it on the fount's inside only. Not necessary to preserve any patinas inside the fount where it can't be seen.

While it can largely flush out most of any kero, naphtha alone isn't exactly effective enough to remove the odor caused by traces of mercaptan.
It is a very persistent chemical. Only minute traces is enough to give off a sensible odor.

How long does the h2o2 need to remove the mercaptan? I only have 2%

Vinegar is used a lot to remove odors in clothing and inside of microwaves and other things, but as for kerosene odor I've never tried it.

I can't tell about 2%. It might seem too feeble.
I'm certain that a 10-30% solution would get the odor off in a pretty short while.
Before using the peroxide, be sure that the internals of the fount is completely free from any oils, grease or fuel.
Lye would be among the best stuffs to use for this. Too bad you don't have any.

In that case, use volatile solvents to clean these off if any. Preferably acetone, followed by denatured alcohol. (These solvents are polar and could easily form mixtures with water).
Finish up the preliminary cleaning with a detergent that could make the internal surface of the fount easily wettable with water. Yes, make the fount's internals 'as hydrophilic as possible'. Remember to rinse with water after the detergent.
The objective is to first make all the surfaces as easy to wet with water as possible, before you introduce any H2O2 solution. This maximizes its effectiveness on everything.

If the peroxide of sufficient concentration is not available, then try other stuffs you might have around. Example, 5% distilled vinegar might be good enough to get rid of some odor. It might not be as effective as the peroxide but still better than nothing. Again, you need to ensure everything is completely wettable inside.

So IPA for a week is what I'm doing right now, I just traveled away from my stove so that'll have to stay. After the IPA soak, I'll do a soak with naphtha, and if that doesn't work i'll do the h2o2. I've already done detergent, and I'm out of dawn, so detergent is no longer an option unfortunately. I think I have some washing soda. Will that work in lieu of lye? will it damage the patina?

+1 on the above advice.

Good luck getting it home.

And what model is this that you’re bring back home. Inquiring minds need to know.

Don't judge too harshly. It was my first post - ever, on any stove related forum. Pictures are in the 3rd post of the thread.

Edit: JK, on Jan 1 of this year, I made my first post right here. (In China and also on the Coleman Collectors Forum).

There're actually plenty of stuffs in China, if you know where to find.
Ok, lets assume it isn't that convenient at the moment.
I suppose you really need the Radius to be completely free of kero odor before it is allowed on the plane.
First, remove the old pump leather and the non-return valve. These will soak up and retain kero odor. Forget about those and replace it with new leather and rubber pip later at home.
Find some common household cures such as coffee grounds, baking soda and white vinegar. Use each of them (if you can get them all) successively. For the first two materials, mix with some hot water and shake. For the third, use it undiluted.
Next, if there isn't much choices at hand, just fill 1/3 of the fount with household chlorine bleach such as regular Clorox or equivalent (5-6% sodium hypochlorite). You won't harm anything with it if you don't leave it in for too long. Shake hard for a minute and leave it for 20 minutes. Pour off and don't reuse the spent liquid.
Repeat a second time and then rinse thoroughly with clean water.
Dry thoroughly and thinly coat the internals with an odor-free oil to prevent rusting and oxidation. If that's not available, just any clean cooking oil would do. It might even mask any remaining traces of fuel odor with its own. :D : At least it smells edible. :mrgreen:
It should be quite free from fuel or kero odor by this stage.
You can finish the rest once it is back to your home in the States.

Why is oxidation a concern? Brass should be damage by the air...

Is this a whole stove you want to ship? If so, I'd remove any removable parts so you don't lose everything if customs doesn't approve. Second, I'd see if the airline has any rules or guidance you can use to ship it as far as ensuring the fuel vessel meets their specs for cleanliness. Especially since they will probably X-ray everything going through. I don't recall the airline or country, but there was one with a checklist and you could include the paperwork showing that you followed it. I believe I saw this on CCS.

Transport it as "Parts" too - list ii that way. disassemble as far as possible - some will not take a "fuel stove", empty or not.
