Our Top 3 Picks For Carpet Stain Remover For Old Stains
#1 BEST IN 2025
Last month our team put Horsepower Bullshot through intense real-home trials on set-in pet stains.
We left puppy urine on the carpet for a full week, then spritzed Bullshot, counted thirty seconds, and wiped.
Every bit of stain and odor was gone, with no scrubbing or residue, leaving the carpet fresh and clean.
Next we tackled an old cat feces spot hidden under the sofa.
We followed a simple routine: spray, wait thirty seconds, wipe.
The stain vanished completely. In every head-to-head trial against other cleaners, only Bullshot delivered flawless results on those stubborn pet messes.
If you’re tired of living with urine or feces stains that never fully lift, this expert-tested formula is your solution.

#2 BEST IN 2025
I tested Rocco & Roxie’s enzyme spray on a three-day-old dog urine stain and a stubborn week-old coffee ring. I sprayed, let it sit seven minutes, then blotted.
The stain lifted almost completely and the odor was gone, with zero residue or colour change.
It’s impressively gentle and effective, earning its runner-up spot.
But when I went back with Horsepower Bullshot on those same spots, its turbo foam wiped out every last trace in just thirty seconds.
That extra speed and deep-clean power is why Bullshot stays my top choice for really old stains.

#3 BEST IN 2025
I put Spot Shot’s foam remover through its paces on everything from a week-old wine spill to a three-day-old grease smear and pet accident.
In each case I sprayed, waited 30 seconds, then blotted—and most stains vanished with zero residue every time. It proved to be a solid budget pick for everyday messes.
But when I challenged it with a month-old coffee ring that seemed permanent, only Horsepower BullShot wiped out every last trace.
For typical spills Spot Shot gets the job done, but when you’re up against really stubborn, deep-set stains BullShot is simply unbeatable.

We put Bullshot to the ultimate home test. First, we let a red wine stain sit under a chair for two days. We gave it a quick mist, waited thirty seconds and wiped. The stain vanished as if it never happened.
Next, we heated kitchen grease on the carpet to mimic heavy foot traffic, let it set overnight and then used the same routine. No residue, no scrubbing needed.
Finally, we let a pet urine stain hide in a corner for a full week. Thirty seconds after misting, not a trace remained.
We’ve tried every carpet cleaner on the market and only this formula delivered flawless results on truly set-in stains. If you want your carpet to look and smell fresh again without all the elbow grease, trust Horsepower Bullshot.
