I was struggling with stain and odours in the house from my two puppies that would (not their fault) soil on my carpet. I had tried a few products to try and eliminate stain and odours to no avail until I saw an ad on Facebook for Petlab. I ordered and tried it though still could see a few stains after I applied. I happened to see some reviews on an ad again for Petlab on Facebook and enquired to the writer what I was doing wrong. She told me to saturate the areas where the stains were and it worked and it also leaves the house smelling really nice. Will try the washing detergent next. Thank you Petlab, Good stuff. :)
