Looking for advice on how to dissipate the persistent odor of oil based polyurethane finish, that can last for months, when applied to the inside of cabinets.
Thank you

I think the only two options are leave the cabinet open for (many) months, or use a fast-drying and/or no-odor finish inside, eg shellac or a newer water-based low-VOC "poly"-type product.
That smell can certainly linger!
Allow plenty of airflow by leaving cabinet doors open and drawers too if applicable. Keep everything at room temperature.
I've recently tried some Varathane brand polyurethane and noticed it took a little longer to stop smelling than my favorite Minwax poly.
Could it be that these newly formulated oil-based products with lower V.O.C.'s take longer to outgas? Maybe.

Best bet is to not use oil-based inside of cabinets, or to pre-finish and let it fully cure before assembly. The pooling of finish in the corners lets solvent soak engrain that is then partially sealed by the finish. It can take years to outgas completely, and then when the heat comes on the next year it will be back.
I wetsanded some shellac with mineral spirits and lost a little into an already glued dado joint 2 years ago & it still stinks today.
Don't finish the inside of the cabinet. Or use water based poly.
Thank you all, I have decided to go with water based poly.
