I used it on stained rugs to see if they could be saved. The stains were there before we moved in 2 years ago. And hoooo. I was super impressed.
I’ve tried peroxide, powdered tide, generic oxi-clean, a carpet spot-clean machine, and none of them helped. But this product lifted out the stainsin just a few mins with very little manual labour.
No bad smells, no change in carpet texture, and no bleach-effect. It just looks like clean carpet now!
