You may have just discovered that you have some mould on your upholstery. Better get rid off it now, before the problem gets worse. Not only does it look unsightly, but these organisms destroy the material that they grow on - by digesting it! Mould also can cause health problems, especially those who are allergic.
If you have mouldy curtains, or your couch has some mould on it, don't go shaking it or beating it. This will release more spores into the air, which will settle around the room and potentially make a bigger problem.
So what do you do?
