We recently replaced the carpet in one room with an engineered wood floor. We have been experiencing an odor similar to coffee coming from the sub-floor in a small area by the steps. Quite some time ago, my grandson spilled part of a cup of coffee on the carpet by the steps. We did shampoo the steps but appears the liquid went into the sub-floor and we neglected to treat the area before the new floor was put on. How can I get rid of the odor?

Rug Doctor sells a pet oder eliminator.

I have actually mopped it on to sub floors and my new dog didn't 'mark his territory' after I did this, you know that it's a good product if a dog can't smell another dogs smells.

Liquid may or may not hurt the new flooring you have, try it in an inconspicuous area first!

It is an option. I can check out the liquid and limitations of my wood to see if liquid is compatible
