Moving house so cot didn't have mattress protector on it (dammit!) and toddler DC has thrown up in the night for the first time. Only discovered it at 8am (he's a champ!) and sleeping bag and sheet are in the wash after a lot of Vanish spray. How the heck do I clean the poor mattress?
Blot up as much as possible with a damp cloth then bio washing powder and water mix to saturate. Leave to dry standing up next to radiator. Then lie flat once dry, very generous covering of bicarb of soda, leave for couple of hours and hoover off.
Make a solution of hot waster & washing up liquid, to get the majority out. Then something like hot water & disinfectant or vanish spray / stain remover type stuff and really scrub at it. Leave it outside to dry / air If you can.
I second using some bicarb washing powder. My daughter vomited all over my mattress a few weeks ago and the smell was horrendous. I tried everything then a friend recommended this. I had already washed and sprayed the area so it was damp. I simply sprinkled loads of bicarbonate washing powder (think it was Persil) I dont think the actual make matters as long as it is non bio. I left it a load of hours with the bedroom window open, came back and hoovered the washing powder off. The smell was completely gone!
Thanks for all your replies- I caught whatever it was baby had, and was 100x more ill. Finally feeling human today. Turned out the mattress did have a waterproof cover, two actually, that I'd not spotted in my panic! So managed to clean those and salvage the situation. Will get some pet enzymes and bicarbonate of soda in for future events...
