Rancid Olive Oil in Un-finished Wood

Hello,

Is there any way to remove old rancid smelling olive oil from wood? I unfortunately took bad advice from a well-meaning person and used olive oil to "condition and protect" an old wooden toy box (heirloom) and some solid wood toys. Now both the toy box and my children's toy's smell horrendous and I am worried about the oil being a health hazard and the smell is overwhelming my living room. I cannot afford to replace these items, my budget is very tight. Is there any way I can clean them, remove the rancid oil and the odor?

Any help or advice would be so greatly appreciated. I cannot believe I was so stupid to not have realized this would happen.

Thank you for your time.

Arbutus Ron here...

Try wiping with clear white vinegar a few times.

After that a sanding should do it to remove the rest. If you are lucky a fine sandpaper will do at 150grit. If not rougher paper at 100 grit or if need be 80 grit will do it. Then sand with finer paper.

Let us know how it goes.

walnut oil NEW

You need to add a chemical agent to polymerize the oil.

If you use plain walnut oil instead for your wood and use the bowl regularly then rancidity is not an issue.

I have never had a problem with rancidity.

If you are really worried then use mineral oil... it can't go bad. If it is food grade then it is safe... just not my first choice.

If both walnut oil and flax oil never polymerize why would you use one and not the other? Why do you avoid linseed (flax) oil? Also, if walnut oil does not polymerize why would you use/recommend it at all? Aren't you worried about the walnut oil going rancid?

Thanks!

Food safe wood finish oil NEW
by: Arbutus Ron

Polymerizing takes place because of additives that make that happen. The only one I would use is Polymerized Tung Oil from Lee Valley, but it is not an officially Food Safe wood finish because of the additives that supposedly evaporate as they dry.

Walnut oil will not polymerize without an additive nor will flax oil which I would avoid.

You may be happiest with the mineral oil as it is odorless and colorless and no chance of going rancid.

Try it and see. You can always try some Tung Oil after if you want as polymerized version will do fine over oiled wood once dry. Try whatever you want and a scrap piece of wood to see if you like it.

But I would keep life simple and just use walnut or mineral oil if you are going to use your bowl a lot.

Thanks NEW

Hi,
Thanks for the response. Everything has been wiped down with vinegar at this point and I have started sanding. I think most things will be salvageable although it will take some time to un-do what I've done.

Would you mind answering a few questions I have about different wood appropriate oils? My questions are as follows:

1. Is it possible to have a polymerizing oil (such as walnut oil) turn rancid before fully drying and polymerizing?

2. I have heard that flax oil (from a health store) never fully polymerizes so it is not suitable for wood finishing? Is that true? If so, how is raw linseed oil different? If it does not fully polymerize will it not turn rancid overtime?

3. I noticed that food grade mineral also contains a very small percentage of mixed tocopherols? Will this cause any issues with the wood over time?

I apologize for all the questions; I want to make sure I make no further mistakes with my wood!

Thank you!
