Does steam cleaning kill mould in carpets? Well, to Put it bluntly, YES. However, you have to make sure that you’re using a good steam cleaner that can reach very high temperatures. Most home units are in the 70 to 150 degrees Celsius or 150 to 300 degrees Fahrenheit range.

At the lower temperatures, the machine will not heat up high enough to be effective. Also, as you are working with water, it could make your mould problem even worse.

How To Steam Clean Mould In Carpets

To kill about 90% of the mould, you should steam the affected area for 15 to 20 seconds, on the highest possible setting.

But before you start, make sure that your machine doesn’t tend to leave things “wet” – this will make the things even worse. Ideally, you want to stick with models that can reach temperatures that are on the higher end of the spectrum.

Can A UV Light Help?

Probably not. UV lights take 1 to 2 hours to kill mould, so if you have to treat an entire carpet, it’s not the best option available.

However, if you only need to address one spot, you can turn on the UV feature on your steam cleaner and leave it to do its thing.

Is It Time To Get The Professionals In?

Depending on the size of the problem, you may need to call in the experts. Mostly because their steam cleaners are a lot more powerful than anything you can buy for use at home.

If you can’t handle your carpet mould problem on your own, check out Federation of Master Cleaners directory of approved cleaners or to see who’s available in your area.
