/diy/ - Do It Yourself

Elderly dog urine went through carpet I am replacing and stained the floor. The smell is not strong but still a little bit there. Maybe I am noseblind but others said it was just a little noticeable. Floor is still hard, not soft at all.
I have a girl who wants to come over I think I can postpone it at least a few days.
What's a quick fix? Clean, Sand, then hide with carpet?
Also feel free to talk shit about my living in filth, he was an inside dog and I loved him too much to throw him outside confused in his elder years.
