Sorry, rather a gross subject!
Are there any foolproof methods for getting out cat sick stains?
I’ve tried spray on carpet cleaners, biological stain/odour cleaners, leaving on a mixture of biological washing powder, just cold water and a hired a carpet cleaning machine, but there are still marks.
I’ve found that any wet method just spreads the stain no matter how much I wipe in towards the middle, so now tend just wipe up as much as possible with dry kitchen roll and vacuum when dry, but it is just disgusting really.
