I'm using Ceaser's Dog Whisper Cleaner for Hardwood it works great and the smell is good and not over powering like the vinegar and water mix. It its an old sent I would do the vinegar and water mix let it sit for 1 in then go over it with the Ceaser...... Good Luck!
Oh yeah I purchased it from PetCO.
