Note: Citric acid is used inn a formulation to treat pet urine stains on household carpets. Dog urine is generally about pH 8-9 which releases ammonia and other odors. Treating the stain with citric acid at pH 2 effectively eliminates the undesirable odors by forming their citrate salts which are not volatile. The residue can then be rinsed away with water.
