Not using your car as often? Doing shorter journeys or leaving it parked outside in damp conditions? If so, you’re not alone, and it can lead to an unwanted problem: car mould.

Moisture build-up inside a vehicle creates the perfect environment for mould to grow, particularly on seats, carpets, and upholstery. Left untreated, it can cause unpleasant odours, staining, and even long-term interior damage.

The good news? With the right products and a few simple steps, car mould can be removed quickly and effectively.

Step 1: removing mould from the car interior

Start by using interior cleaning products designed to tackle bacteria, stains, and deep-set grime.

A heavy-duty interior cleaner, such as Meguiars Heavy Duty Multi-Purpose Cleaner is ideal for breaking down mould on:

  • Fabric seats

  • Carpets

  • Upholstery

  • Floor mats

Spray directly onto the affected area, agitate gently, and wipe clean.

Tackling stains left by mould

If you find that your car mould has resulted in staining to your carpet and upholstery, it’s time to use Meguiar’s Foaming floor Mat Cleaner. It’s not only effective not only on mould but also on everyday marks like food, drink, or grease.

Restore interior freshness

Once you’ve battled the bulk of the mould, it’s best to then use a product that will restore your car interior’s freshness and shine. The Meguiar’s Ultimate Interior Detailer will revitalise your car interior, restoring its original appearance.

Step 2: preventing mould from coming back

After removing mould, prevention is key. Moisture control and regular cleaning will reduce the chance of regrowth.

Using carpet and mat cleaners will help:

  • Neutralise odours

  • Remove moisture-trapping dirt

  • Maintain interior freshness

We recommend using the Turtle Wax Power Out Carpet & Mats Heavy Duty Cleaner to help maintain your vehicle’s freshness. The chemical ingredient within the spray that is used to eliminate the bad odours will also help prevent the re-emergence of mould but will not necessarily stop it completely. Regularly using the Power Out Carpet & Mats Heavy Duty Cleaner will help your car interior stay fresh, preventing any further mould build-up.
