How to Identify Carpet Mould

Here are some signs that say mould is hidden somewhere in your carpet.

Visible Mould Growth

More often than not, you’ll find mould growing in dark places, but that doesn’t eliminate the fact that it can also grow in carpet fibres. So, inspect the padding and look underneath the carpet for mould so you don’t miss anything.

Water Damage

If your carpet has been exposed to water and not dried, mould will start growing in 24 to 48 hours. That means you’ll have to act fast about getting rid of it.

Mildew In Carpet

Most times, mildew is the starting point for a mould problem in your carpets. They look similar but still differ in their colour. Mildew can be white, yellow or grey, while a mould is blue, red, black or green.

Stains And Odours

Musty, sour, or foul smells usually point to the presence of mould in your carpet. Certain discolourations and stains could also mean mould. The best way to be sure is to call Top Carpet Cleaners for a sample test.

How to Clean Mould from Carpet (Naturally or with Chemicals)

There are two main methods we recommend when removing mould from your carpet one is natural, and the other is not. You can determine the best method for cleaning carpets based on their condition or your situation.

How To Remove Mould From Carpet Naturally

All you need is vinegar, baking soda and ventilation for this method. There’s no risk of harmful chemicals getting to the kids or pets.

Things You’ll Need

  • Baking Soda
  • Distilled white vinegar
  • Spray bottle
  • Fan or humidifier (optional)
  • Stiff-bristled brushes

Step 1: Inspect The Carpet

Use the above guide to scrutinise your carpets. Take time to pinpoint every source of mould and where it’s grown.

Step 2: Ensure There Is Proper Ventilation

As previously stated, mould thrives in darkness, moisture, and warmth. So, turning on a fan or opening the window will reduce the humidity in the room. This proper ventilation will also reduce undesirable odours.

Step 3: Sprinkle Baking Soda

One critical factor that promotes mould growth is moisture, so you must eliminate it. Baking soda is suitable for the job as it absorbs moisture and reduces odours.

Sprinkle baking soda over the affected area of the carpet. Leave it overnight. Then using a vacuum, remove the baking soda the following day.

Step 4: Spray The Vinegar

As a final step, spray the distilled white vinegar onto the carpet. Use the stiff brush to scrub on the light coat of vinegar. Then use a blow dryer or fan to get the moisture out.

How To Remove Mould From Carpets Using Chemicals

You should choose chemicals if you want a more effective way to kill mould. You may even need to call in Top Carpet Cleaners to ensure the cleaning is thorough.

You’ll want to carry out steps 1, 2, and 3 from above. Then try the following.

Use An Anti-Mould Treatment

You’ll find anti-mould cleaners at most hardware and supply stores. Get the one safe for carpets, as the ones intended for the kitchen or bathroom could damage it.

Use the anti-mould treatment as per the manufacturer’s instructions. And if you can’t get one, you can substitute with half a cup of colour-safe bleach in one gallon of water.

Apply Chlorine Dioxide

Mould cleaners commonly contain chlorine dioxide, which is very effective at removing moulds. However, it requires caution as it can discolour the carpet.

To be safe, test the product on a small carpet area. Follow the instructions on the products and let them dry before making a decision. Some products require a dry or wet vacuum to remove them at the end.

Leave It To The Professionals

If you feel you can’t carry out these methods well, you should call professionals. Top Carpet Cleaners use state-of-the-art equipment and products to kill mould in your carpets.

You can always tell them about your concerns if you have any.

Mould In Carpet Health Risks

Aside from the fact that mould is an unpleasant sight to see, it can pose a risk to your health. It’s common to get allergic reactions or respiratory problems due to mould.

How Problematic Can Mould Be On Your Health?

Mould produces irritants, allergens (substances that cause allergic reactions), and sometimes toxic substances.

Touching or inhaling mould spores can trigger an allergic reaction. These reactions include red eyes, skin rash, a runny nose, sneezing or an asthma attack.

Why Cleaning Mould From Carpet Necessary

Mould damages the carpet over time. If left too long, the mould becomes untreatable and may prompt a carpet replacement.

Hire professionals like Top carpet cleaning to remove the carpet mould as soon as possible. This will inevitably prolong your carpet's life.
