Help! I live in Southern Spain and we have had torrential rain for weeks and as we have no heating the apartment has got quite damp. There are some damp patches on the ceiling in my DS?s room (he?s just about to turn 2). I have been using a de-humidifier in there when he isn?t it there and that has been making a big difference but I was horrified to discover yesterday that there is some mould (black spots) on the underside of his foam mattress. I put it outside yesterday to dry it out (finally some sun) but I wanted some help with how to clean the mattress to get rid of the mould and advice on whether it is still safe for him to use it again once I have got rid of the mould or do I need to buy a new one instead. He is away for a couple of days now so I have time to sort it out. Thanks in advance for your help!
