We have an (expensive) infant car seat we bought for our daughter that we were planning to reuse. It's been in storage for just under a year and we've taken it out to find mould on the shoulder straps. Have emailed Nuna, the manufacturer, as we know you can't use chemicals etc on car seat materials or hot wash them as they are then no longer safe in the event of an accident. They have basically said bin the seat as there's no safe way to clean the mould off. We could buy new straps etc but the mould could have penetrated the shell of the seat and be unsafe.
We are leaning towards buying a new one as clearly we don't want to put our newborn baby at risk either from mould or from intensive efforts to remove the mould that could weaken the materials. However it feels tragic to spend so much money on a new seat when we have one already, and also incredibly wasteful environmentally. WWYD?
NB for anyone that thinks we should have stored it better, I fully agree, sadly PILs kindly offered to store it in their garage and assured me it was safely wrapped in damp proof material. Spoiler alert - it wasn't.
