My own fault, I left a chicken salad unattended for about 3 milliseconds and our dog scoffed most of it, unfortunately large quantities (for a dog) of red onion. So, £60 vets bill later she's OK, but woozy and still a bit iffy, so I walked her around for ten mins or so, all seemed OK. I have covered the back seat with a waterproof cover plus several of the sick pads from the vets, and 500 yards from my house, she unleashed hell, missing all of the covers and pads and all over the rear door and footwell. I've cleaned up the worst, but there's an unsightly mark in the carpet, so wondering what to use on other than general bio washing liquid....

If you have access to a decent APC you can try that on it. Or better still a wet vac. I would think household carpet cleaner (e.g. 1001 mousse) should be safe to have a pop with too?

Autosmart biobrisk is what you want for removing puke smells from cars. I also use it for when my toddler projectile chunders Over the carpet. You can find it on ebay
