Effective odor treatment focuses on the contamination producing the odor. Fragrance alone cannot remove a source embedded in carpet, backing or cushion. The Carpet and Rug Institute (CRI) notes that some pet-odor products may simply mask odors if the underlying urine is not completely removed.

Urine is the most common cause of lingering carpet odor.
Sources below the fibers need treatment that reaches them.
Enzymes break down organic sources when given contact and time.
Returning odor means some source remains, often in the pad.
