I never write reviews for products unless I'm completely blown away, or completely disappointed. This product did not disappoint. I had consistent results time and time again.
We have three large dogs, and our house is constantly either full of fur, dog toys, mysterious puddles, vomit from yesterday's trash excavation, or your bi-monthly bout of explosive diarrhea. We just received our second bottle in the mail, which I trekked down the driveway, through the snow to get from the mailbox. You see, our wonderful dogs thought it would be a great idea to get into a giant bag of uncooked rice two days ago. After discovering the empty bag and three plump furry bellies, all PetMD diagnosis pointed to imminent death by combustion, or unrelenting explosive diarrhea. We experienced the latter. Every two hours, we were woken up to the desperate scratches on the door to be let out. One can only crawl out of bed so many times...long story short, we had two shatting incidents in which I thought we'd have to rip out all the carpet and sell our house. Both times, R&R not only got the stain completely out of the carpet, but it completely removed the house of the ungodly smell of our dogs' transgressions!!
If you're hesitant on the price, which I was at first, your desperation to remove your carpet of brown and yellow spots will be rewarded by giving this a try. When I tell you this stuff is MAGIC IN A BOTTLE, I'm not exaggerating. Vomit, urine, diarrhea, butt juice--I know what you're thinking..."What the hell kinda dogs do they own?!" R&R got all of it out of the carpet. I'll say it again...MAGIC IN A BOTTLE. $20 for magic? Do it. We will never buy another product again for as long as we both shall live. Or at least as long as we have carpet.
On another note, R&R is also safe on fabrics of all colors. I just tested this earlier when I discovered our 85lb mutt licking his junk on our bed. The spot spot came right out! I could go on, but the house is eerily quiet which leads my dog mom brain to believe that there's trouble being conceived.
tldr; BUY THIS. It's worth the $20 to not have to smell or look at your dogs' pee, poo, vomit, butt juice stains in your house. Safe on virtually all porous surfaces--including bedding and couches. MAGIC IN A BOTTLE. The end.
