Garage full of mould - Chuck or salvageable?

[BeenPurple]

Garage has started growing mould over everything. The dart board is covered and the wooden bits of the shelving units are growing mould. Single brick detached garage. What the fuck can I do? It’s really damp in there, but no leak. Can I spray the dartboard with mould killer stuff or will to just bleach it? We treated the wooden shelves once before to stop them growing, MDF type inserts in metal shelves. Going to put a dehumidifier in there and leave the door open on dry days.
Any other suggestions as it’s soul destroying seeing all the camping stuff etc, is there some kind of bug bomb type thing we can set off and will kill all the spores?

So dart board
YABU - Throw
YANBU - salvageable and safe to use say a dettol kitchen spray or mould spray.

Spray mould killer and save what you can.

HG mould killer is nothing short of miraculous.

I’d throw the dart board personally. It’s very aggravating when stuff like this happens.

In the US I know any sign of mould and you get someone to stick a tent over your house and fog it. Over here we seem a bit more blaze and live with it.
Wonder if there’s any way to fog the garage? I know it will come back as it’s so damp, but might give it a chance.

@harrassedmumto3 should have 2 bottles of HG arriving today
