We have been smelling this horrible smell in my baby’s car seat and I figured it was just the little shoulder pads getting yucky from drool. Guys. I took the cushioning out and there was crusty dried spit up and milk all in there. The smell was so horrendous we were gagging. I took off everything that’s removable to wash and then scrubbed everything else down and sprayed with febreeze but it still reeks. Anyone have tips for cleaning baby’s car seat?
