I was very disappointed with this product. I purchased it to help rid my furniture of faint doggy smell. We own a small relatively 'unstinky' pug who is routinely bathed and only sits on the furniture in the evening with my husband and I. After multiple applications of this product, I can detect no change. Also, I tried it on grout - both scrubbed and just sprayed on - with little to no change. I will not be repurchasing this product.
