How can I remove skunk smell from house?
I have used that mixture with good success.  Make sure to wipe down everything that the dog might have come in contact with, and I mean everything. Floors, walls, trim, doors, etc. You might need to repeat the procedure a few days later.

The skunk odor tends to linger quite a bit and you will find that it gradually reduces in intensity over time but is still evident.  Anytime your dog gets wet you smell it, likely for months!

If it is really bad and does not go away you might opt to bring in a professional cleaning company who will have stronger chemicals to deal with it.
