Maybe in a gallon zip lock freezer bag with a box of baking soda?
I wouldn't keep the pen in a container with any chemical compound. I wouldn't even have done any of the before things you did to it.
Stop wiping it down with basic and acidic ingredients. You're going to absolutely destroy the pen trying to accelerate something that will fade on its own in a few weeks.
The volatile compounds may have gotten into the porous material, but what goes in will come out with good ventilation and time.
Don't put it in a bag, that will just seal everything in, and if anything offgasses from the bicarbonate (which is alkali) as well as minute amounts of the bicarb itself vaporizing slowly and possibly depositing onto the pen itself, into a enclosed space could utterly destroy the pen. Everything you've been putting on it has been acidic or basic and is NOT GOOD FOR RUBBERS OR PLASTIC.
The bicarb itself won't "suck" the odors from the plastic. If they absorb any odors at all, it will be just absorbing the odors that are naturally vaporized into the air, and would just dissipate. The point of baking soda in a cupboard or fridge is to just absorb the odors sitting in the air. It won't remove the odors from that rotten cheese, it will just absorb what does come off. So a ventilated room would do the exact same purpose. You'd have to literally soak the pen in a bicarb solution. WHICH IS A TERRIBLE IDEA.
The most I'll ever touch pens with is a 10% ammonia solution (occasionally dilute bleach for de-staining some pens, but that's only in emergencies when I used an ink that I shouldn't... stupid pelikan m205 demonstrator plastic.) and even then, ONLY when absolutely necessary, touching as few parts of the pen as possible, and only for the shortest period of time possible.
Acrylics should be relatively inert, but ABS, celluloid, the bioplastics, and ebonite are all BAD things to be putting any solvent other than water onto.
Just take it and put it on a table in a room for a few weeks. The smell will fade. All volatiles (odor causing compounds) will eventually leave. If they're volatile enough to smell, that means the odor causing compounds are escaping into the air, which means they will eventually all leave with time. Noodlers pens stink, but the odor fades within a few weeks. Newly cut acrylic stinks, but that odor fades quickly too.
Think about it like a bottlecap with a few drops of denatured alcohol in it. The alcohol stinks like hell, but it eventually evaporates and you are left with no smell. Alcohol may vaporize faster than the compounds on your pen, but the principle, vapor pressure, is the same.
