Summer Carpet Cleaning in Commercial Buildings and Schools: Best Practices and Pitfalls to Avoid

As summer approaches, administrators and facility managers in commercial buildings and schools often turn their attention to maintenance tasks, and one crucial aspect that shouldn’t be overlooked is carpet cleaning. While summer presents an opportune time for deep cleaning carpets in these environments, it also comes with its own set of challenges. In this article, we’ll explore the best practices for summer carpet cleaning in commercial buildings and schools while highlighting common pitfalls associated with the season.

Why Summer Carpet Cleaning Matters in Commercial Buildings and Schools

Carpeted areas in commercial buildings and schools endure heavy foot traffic daily, leading to the accumulation of dirt, dust, allergens, and potentially harmful microorganisms. Regular vacuuming and spot treatment are essential maintenance practices, but they’re not sufficient for removing deeply embedded grime.

During summer break, maintenance crews have the opportunity to thoroughly extract carpets, making summer the prime time for this essential task in most buildings. Warmer temperatures and heightened humidity levels during this season can create an environment conducive to mold and mildew growth if best practices are not followed. In most schools, summer becomes the only window for conducting deep extraction cleaning, effectively eliminating accumulated dirt, allergens, and microbial contaminants, while also preventing the onset of mold growth.

Best Practices for Summer Carpet Cleaning in Commercial Buildings and Schools

  1. Deep Extraction Cleaning: Utilize specialized equipment designed for commercial settings to penetrate deep into carpet fibers and extract dirt, stains, and allergens effectively. Ensure thorough cleaning of high-traffic areas and spots prone to soiling.
  2. Prespraying Carpet: Before deep extraction, prespray the carpet with a cleaning solution like Triple-S Triple Carpet Prespray and Extraction Cleaner or Hillyard Carpet Prespray. This step helps break down stubborn stains and loosens embedded dirt for more efficient extraction.
  3. Proper Carpet Spotting Techniques: Prioritize spot treatment of visible stains using industry-approved spotting solutions and techniques. Addressing stains promptly prevents them from setting or spreading during the cleaning process. We recommend the Hillyard Double Down Spotter or a combination of the Triple-S Bio Enzymatic spotter targeted towards organic soils like coffee coupled with the Triple-S general purpose spotter targeted at inorganic soils like inks and dyes.

Common Pitfalls of Summer Carpet Extraction in Commercial Buildings and Schools

  1. High Humidity: Summer humidity prolongs carpet drying times in large commercial spaces, increasing the risk of mold and mildew growth. Implement strategies such as proper ventilation and scheduling cleaning during low-occupancy periods to expedite drying and mitigate moisture-related issues.
  2. High Temperatures: Elevated temperatures can accelerate the evaporation of cleaning solutions, potentially leaving behind residue that attracts dirt. Adjust cleaning procedures to account for higher temperatures and select solutions that evaporate cleanly without leaving a residue. If carpets are heavily soiled, incorporate the Hillyard Carpet pH Rinse into the process. After prespraying the carpet, use the Hillyard Carpet pH Rinse in the tank of your extractor for the rinse step.
  3. Inadequate Drying Time: Rushing the drying process can result in incomplete evaporation, leaving carpets damp and susceptible to mold growth. Allow ample time for carpets to dry thoroughly before resuming normal foot traffic, considering factors such as airflow and humidity levels. Never extract carpet at the end of the week. Many HVAC systems are programmed differently on weekends when buildings are unoccupied which can impact dry times. If your building is unairconditioned, air flow is key. Open windows and use air dryers to speed the drying process.
  4. Overwetting: Excessive use of cleaning solutions or water during extraction can oversaturate carpets, leading to prolonged drying times and potential damage to carpet fibers. Adhere to manufacturer guidelines for solution dilution and extraction techniques to avoid overwetting and ensure optimal cleaning outcomes.


Summer presents an ideal opportunity for deep cleaning carpets in commercial buildings and schools to maintain a clean, healthy indoor environment for occupants. By following best practices such as deep extraction cleaning, prespraying, and proper spotting techniques, facility managers can effectively remove dirt, stains, and allergens from carpets. However, it’s essential to be aware of common pitfalls associated with summer carpet cleaning, such as high humidity and temperatures, and take proactive measures to mitigate these risks. With the right approach, carpets in commercial settings will remain clean, fresh, and mold-free throughout the summer season and beyond, promoting a conducive environment for work and learning.
