Best carpet odor removers

Top pick: Rocco & Roxie Stain & Odor Eliminator. It's the one most people reach for on pet urine in carpet: an enzyme formula that breaks down the source of the smell rather than masking it, and it's rated well by a lot of owners. Spray, let it dwell, blot — repeat on old spots.

Who the others suit:

• EcoStrong Pet Stain and Odor Eliminator — unscented, so best if you're sensitive to fragrance or the pet is.
• Clean-eez Stain-eez — bio-enzymatic and bleach-free, a good choice for wool or delicate rugs.
• Angry Orange Pet Odor Eliminator Spray — probiotic-based and citrus-scented; pick it if you want a fresh smell left behind.
• OxiClean or Clorox pet carpet sprays — cheap, easy-to-find options for fresh accidents and light odors.
• Hoover Pet Carpet Cleaner Solution — only if you have a carpet-cleaning machine and want to treat the whole room.
• FurryFreshness gallon 2-pack — for heavy, repeated use across a whole house.

Whatever you choose, soak the pad underneath: odor comes back if the urine in the padding is left.
