Clean and dry carpet does not promote mold growth. In fact, you have to really work hard to grow mold on carpet. With the exception of wool, carpet fibers are synthetic and cannot serve as food for mold.
However, mold grows in any moist environment where dirt and dust provide nutrients. If carpet is not properly cleaned and dried, and is exposed to excess moisture, it will grow mold just as will grouted tile or vinyl shower curtains.
Remember the formula: Clean + Dry Carpet = No Mold
Cleaning Carpet for Mold Prevention
- Vacuum slowly and thoroughly with a CRI-approved vacuum cleaner to remove organic dirt and dust, the food source for mold.
- If you use do-it-yourself (DIY) carpet cleaning equipment, use a machine approved by CRI that removes maximum moisture.
- Use a CRI Seal of Approval (SOA) cleaning solution.
- Be patient and don’t over-wet the carpet. Extract as much of the water as possible — do not rush this step.
- Wait until the carpet dries before replacing furniture or walking on carpet. This may take up to 12 hours, most typically six to eight.
- Ventilate. Open windows if outdoor weather conditions (temperature, humidity) permit, or put the AC on moderate settings (72-78°F). Never close up a wet, newly cleaned carpet; keep air circulating. You want the fastest dry possible, to prevent mold growth and to allow earlier use.
- Hire a professional CRI SOA Service Provider to periodically deep clean your carpet.
