How to remove Ethanethiol from household natural gas? Household natural gas is injected with a little bit of Ethanethiol to make it a distinctive odor for safety purposes.

But, if it is used to drive cars (*), its odor is sensible and it is annoying.

Is there a way to remove this from the household gas (which is mainly the mix of 90% methane and 10% ethane) on a home budget scale?

My first idea is to have some type of chemicaly which could be inserted into the empty bottle.

(*) In most countries, this can be done legally, although it has to follow relatively strict safety and tax regulations.
Just an idea: You can pass the gas through a bleach solution that can oxidize the thiol. I have no idea how effective this can be since the human smell is extremely sensitive to ethanethiol (to the scale of parts per billion). One possible set-up (very common in organic labs) is shown in this picture. The end Buchner flask should contain bleach and not HCl. The other conical is a safety measure in case you have suck back of the bleach solution.
