Just that really, opened an overflowing cupboard and found a toy that had batteries (normal AA type batteries) that hasn't been used for a while. I'm going to get rid of the toy as I don't want a child touching that substance but basically it fell out of the cupboard when I opened it so the white substance is most likely on my carpet (which I will hooover off), on my hands (washed them) but also on loads of other board games. Should I unload the cupboard and clean all those boxes up? I am worried about this powder burning or blinding my kids or something - advise me please!
