Mould and Asthma

I have to be very vigilant about mould because of Bob's Asthma and came home to all windows with black mould on them. I've tackled them with vinegar but then he whinges and coughs and does his drama queen thing about the smell of vinegar. Short of cutting his head off I'm at a loss to find something to use. I usually do jobs like that when he's at bowls on Wednesdays but didn't get to it yesterday, so today we are freezing to south west winds because all the windows have to be open because of the vinegar smell.

What spices do you have in the cupboard? - set them to simmer on the stove in some water LOL
