Re: Home Airfreshener's
I won't use air fresheners for the same reason, in addition the scents are so synthetic.
I use St Eval tin candles - they are made in Cornwall. They do not smoke, they last a long time and the fragrances are very natural. I have lavender ones in the bathrooms and loos, thyme & mint in the kitchen, and rose or lavender in the bedrooms. This is the website - but it is worth shopping around because other sites often have special offers

As for black mould - there are several products on the market for removing this and preventing its recurrence - check on Amazon or in places like B&Q
