I've seen mentioned a few times on this site that vineger is good to use to remove the smell of puppy accidents out of carpets.
Do you just use this neat or with water? if with water, do you use hot or cold and how much of each?
I use a 50/50 mix of white vinegar and water. I don't worry too much about the water temperature because I mix it in a big spray bottle and put it away. By the time I use it, it's room temperature.
Thank you. A spray bottle is a good idea
