Hello all, any advice really appreciated:
Cat weed on the sofa, luckily caught it straight away so whipped the covers off (SAYS washable so fingers crossed) and stuck them in the wash with biological powder.
Under the main covers was another cotton cover with a padded top, and then a sponge inner. I've cleaned up the inners best I can and stuck them in the sun (finally, sun!) to dry, but wondering whether to stick the covers with padded tops in the washing machine, or whether that would be A Seriously Bad Idea.
It's an Ikea Stocksund if that's any help.
Also, anyone had a similar situation and managed to prevent reoffending? She's usually really good :(
