Yes, we have that delightful problem! Grace has just been violently sick in the car. We’ve got her cleaned up ok, and she’s sleeping now, and we’ve stripped out the bits of the car seat which can be washed, but a lot of it is “in situ”. Obviously we have cleaned it (as best we can in the dark!) but it reeks! I don’t want to “febreeze” it - and we haven’t got any anyway, but is there anything I can use to get rid of the smell?!
