the best there is. you can't go wrong. i had 2 chairs i was going to throw away. after cleaning i put them in my living and use them every day.

Cleaned 12,000 sq ft of our office carpet of 12 years that nobody else could. Nobody in the office could remember the different color specks that the carpet originally had until they cleaned it. Also clean some of our cubicles on the plant floor that had multiple grease and heavy dirt stains - they came out like new without having to buy new cubicle walls.
