Q: I believe my daughter spilled a cup of milk that seeped through her area rug and onto the unfinished wood floor in her room. It smells so bad and the stain on the floor is back. I’ve tried cleaning both rug and floor with no avail the smell keeps coming back what can I do?
A: Perhaps a diluted vinegar solution would work?
Follow-up Q: How diluted and what kind of vinegar?
A: Just plain white vinegar. You will only need a bit. I’d mix it about 50/50. You are just trying to neutralize the milk protein. The vinegar isn’t going to hurt anything unless you flooded the floor with a gallon of it. That would never be good.
