My toddler, who I thought we'd successfully potty trained weeks ago, has just done a huge wee on the sofa. The covers are in the machine on a hand wash cycle which they have survived in the past, but how do I deal with the wee soaked foam seats? If I put them in water they'll never dry will they? But if I just surface clean it won't get out the soaked in wee. Has anyone got any ideas / experience, please?!
