How remove/eliminate burnt smell odor from wood? (countertop, microwave, paint)

[Jedi5]

So we sorta had a little microwave mishap over the weekend
where some food was very very very well done.

No fire, microwave didn't burn down.
House was just really really smokey.

The microwave is a countertop that sat in a kitchen cabinet.
There is a little strip of wood, maybe 2ft wide that was under the microwave.
That little strip of wood has a burnt odor that I cannot remove.
Replacing the strip is not an option.

I've tried to wash or scrub down with vinegar.
I've sprinkled baking soda over it.
I've made a baking soda paste which I applied over the strip of wood.

The odor isn't as bad as before but it's still there.
I'd say from 1-10 it's maybe a 4?

Is there anything else I can try to do to remove or eliminate the odor?

If I paint the strip, would that help or no?

Thanks!

A primer/sealer will take care of that, if you want it done- NOW.

Or, just over time it will dissipate. 4/10 is pretty minuscule.

Thanks K!

Is there a brand of sealer that works better than others?

I sorta do want it done now as our house is under contract...
