Last night we were cleaning up in Lilly's playpen which sits on wood laminate flooring and noticed when we lifted her little floor cushion there was a dried urine stain. We look for puddles and smell bedding, but have never thought to try and see dried puddles on wood (which is more difficult that you think). I wash the floor once a week. Anyway, I cleaned it up, thought nothing of it and always being thankful its not carpet UNTIL I noticed that the plank of laminate flooring appeared to have raised cracks like it warped where the 2 peices of wood met.....it never had this before. So after I washed the floor with water and vinegar (which I swear by to rid urine stains/smells on everything) I leaned down to smell the floor and discovered that the urine smell was deep down in those raised little cracks!!!! She will smell that forever!! So I poured baking soda on it to sit over night since it is known for absorbing smells & it seems to have worked but a dogs sense of smell is a million times better. Never ever in a million years did I ever think it could warp my floor like that and seep in!! Any suggestions on how to get rid of the smell other than replacing my wood planks?
