Black mold....

[Admiral]

I can totally agree about the vinegar and bicarb (both so good for many things)

Also, if it doesn't sound too crazy timing is off the essence!

A waning moon would be the best time to attack it to ensure it stays away longer. In March around the 17 - 31.

Thanks for that Clubby. The waning moon thing sounds a bit wierd but I will don my druid robe, put on a pointy hat and dance around a bonfire on the 17th before tackling the black mold stuff.
