How Can I Get Rid of Moldy Smell from Formerly Wet Space Under Kitchen Sink.

If t's just mustiness, try wiping the inside cabinet under the sink with vinegar or a mixture of vinegar and water. Vinegar is a clean smell and is great at taking care of odors. Vinegar doesn't mask odors, it actually removes them.

If that fails, then there may be some left over mold that wasn't taken are of initially and you may need to take things out again and find the cause of the remaining mold. Because, the things, if there is mold, nothing can fixit, except to gt rid of the source of the mold.

Baking soda on newspaper. Crushed charcoal. Leaving the door open and sticking a fan there so that the air can circulate.

If you smell mold, there may be mold. You said rotten wood was removed, but what happened after? If new wood was put in without dealing with the walls or subfloor, you may have to open it all back up to treat it.

If everything was inspected, treated and replaces and this is just a lingering mustiness, then remove the cabinet doors so airflow can do it's thing.

I'd definitely put O. of those damp absorb containers in there.
Then, freshly ground coffee beans on a plate should do it!

when our sink has leaked we took everything out, removed any rotten wood, and left a fan running on it for at least a day (2 is better) before replacing the rotted wood.
it sounds as if you didn't get all the wet out. i'd try taking everything out and putting a bowl of baking soda in and leaving it for a couple of days. if that doesn't do it, you need to go back in and remove whatever rotten wood you may have missed.

A plastic container of DampRid under there with some of the other cleaning methods will work wonders.

We have a DampRid in our master bath (it is tiny and not well ventilated). It really helps absorb extra moisture.
