Zingy lemon scent
I used this solution to clean an area rug that my dog had urinated upon. The scent of the cleaning solution during application was that of tart lemon.  It was a pleasant and zingy smell that wasn't too overpowering.  Within about 3-5 minutes after application the scent of the lemon began to intensify and got a little fumy, it wasn't enough to be noxious or cause breathing issues, but going in another room while you wait might be more comfortable.  I followed the directions and let the solution stand for 10 or so minutes before using a carpet shampooing extractor to get the funk out.  It did seem to clean the area rug well and as an extra precaution against stink, I spritzed a little more cleaner on the rug surface to help it stay fresh.  I believe this is a quality cleaning product that does what it claims and since I like the scent of lemon, I think this stuff smells great.
