Laundry issues!!!!

So I’m looking for a new detergent. I use seven generation free and clear but our clothes still smell after I use it. My daughters especially smell like cheese because of any split milk on her. I don’t want an overpowering fragrance but one that will get rid of simple odors like that. Thank you for your help!

We do her laundry every other day just about so it’s not sitting around for too long. If I know about it I wash it out but if it happened at daycare I have no clue and I can’t do laundry every night.
