Why should urine stains be treated as soon as possible?
Besides the obvious health and sanitary issues left untreated, urine causes difficult to remove yellow stains, or worse yet, dye loss. Over time as urine sits in your carpet it becomes highly alkaline, and can bleach out primary carpet dyes until your left with a yellowish or white discoloration. At that point the only option to repair the damage is to re-dye the spot or patch the carpet.
