Ddog has just been sick on our landing carpet. I've rinsed the area with warm soapy water and patted it dry, then sprayed it, but is there anything I can do about the inevitable brown stain? He'd been eating tripe shortly before so the vom was dark brown, sludgy and horrible (since you ask) 

Sod's law it's happened 2 weeks before we leave a rented property... does anyone have any deposit-saving advice?
