Came across some rat nasty section 8 carpet the other day. Before cleaning I rinsed using the Power Rinse and WOW. Follow with Bio Pro 10K, ( FOLLOWED THE DIRECTIONS ) pre-sprayed and rinsed again. Carpets came out nicely and apartment manager was overly impressed.
Works as advertised. Price is decent,
Quality product I would recommend to other people
Used the acid rinse after cleaning some filthy area rugs with BioPro 10K. They looked brand new afterwards. I’m looking forward to using it often.
