Steam cleaning is also used for removing mould stains too but the term ‘steam cleaning’ often refers to a number of different techniques.
It’s important that you know which one you’re using because the results can be disastrous if you get it wrong.
When people think of steam cleaning carpets they mostly refer to using hot water and detergent extraction techniques.
Although this method will remove many stains and mould it will not eliminate the mould spores permanently because the water temperatures are simply not high enough.
This means that the mould can quickly return especially as the wet carpet presents highly favourable conditions for mould growth while it dries out.
The other problem with this method is that the water can damage carpets and fabrics so do some spot testing in out of the way places first.
Steam vapour cleaning is a type of steam cleaning that originated in Europe. This method transforms water into a dry steam that may be hot enough to kill mould without the water saturation issue.
However, this technique may still cause damage to delicate fabrics and carpets so must be used with care.
You can also use steam cleaners on other surfaces in the house such as sealed timber, concrete, tiles and grout but it is not recommended for silicone joints and anodised surfaces.
To sum up:
Steam cleaners have value as a general cleaner but if you are serious about getting rid of mould permanently it’s best to get the professionals in.
