I've got some really old dog urine stains on the basement carpet in the house I just bought. They're likely at least a year old.

Is there any way to clean such old stains? I'd rather not have to replace all the carpet.

Thanks!
Marc

Hire a pro. They have access to chemicals that you can't get. One of the special cleaners can only be bought in a 55 gallon drum.
Even they won't be able to get the smell out of the pad, tho.

Sure hope there was a vaper barrier built into that pad or under it. If not the odor may have soaked into slab.

What's odd is there is no smell at all. I guess the owners at least tried to clean it up each time. There are just dark stains on my light carpet.
