I have tan carpet and a dog urine stain, I’ve tried Nature’s Miracle and also another remover that Petsmart suggested but it’s still there? the smell is gone. I also have a huge old coffee stain, I’m going to be cleaning our carpet this week so I wanted to treat the stains first. Any suggestions??? any tips that don’t involve harsh chemicals would be great! ( I have a 1 year old on the loose)
