Maintaining commercial washers free from mold and mildew is crucial for ensuring the longevity of the machines and the hygiene of the laundry processed within them. This guide provides detailed information and practical tips for maintaining commercial washers and promoting fresh laundry.

What are Mold and Mildew?

Mold and mildew are fungi that thrive in moist, warm environments. Mold tends to be black or green and can penetrate beneath surfaces where it grows, while mildew is usually gray or white and remains on the surface. Both can produce unpleasant odors and deteriorate fabric quality.

Why They Thrive in Commercial Washers

Commercial washers, due to their frequent use and exposure to moisture and organic materials (like skin cells and oils), provide an ideal breeding ground for mold and mildew. Without proper care, these fungi can accumulate quickly, leading to health issues and operational problems in laundry facilities.

Prevention Strategies

Preventing mold and mildew in commercial washers involves routine maintenance and careful operation of the equipment. Below are strategies to help maintain the cleanliness and efficiency of your washers.

Regular Cleaning and Maintenance

Daily and Weekly Tasks

• Daily: Wipe down the interior surfaces of the washers, including gaskets and seals, to remove moisture and any residue. 
• Weekly: Use a washer-safe cleaner to deep clean the drum and other components susceptible to mold growth. 
• Use Enzymatic Cleaners: These cleaners are particularly effective at breaking down organic materials (like body oils and sweat) that mold and mildew feed on. Regular use can prevent the buildup of these substances, which contribute to fungus growth. 
• Vinegar Rinses: Incorporate white vinegar rinses into your weekly maintenance routine. Vinegar is a natural disinfectant that can help kill spores before they become a problem. 
• Gasket and Seal Care: Pay extra attention to gaskets and seals, which are often overlooked yet critical areas where moisture collects and mold tends to grow. Use a dedicated soft brush or cloth to clean these areas thoroughly.

Monthly Deep Cleaning

• Use a mixture of hot water and a non-abrasive cleaner to thoroughly clean all components.
• Inspect and clean filters and hoses to prevent clogs that can retain moisture.

Optimal Usage Practices

Load Sizing

Ensure that wash loads are appropriately sized to prevent excessive moisture accumulation. Overloading can trap moisture, while underloading may lead to inefficient water use that increases humidity levels inside the machine.

Choice of Detergents

Use high-quality detergents that are effective at low temperatures. Lower water temperatures can reduce the risk of mold growth, but only if the detergent is capable of cleaning effectively at these temperatures.

Tips for Mold and Mildew Control

Moisture Sensors

• Automated Humidity Monitors: Install systems that automatically monitor and adjust the humidity levels in the laundry room. These systems can trigger exhaust fans or dehumidifiers when moisture levels exceed a preset threshold. 
• Moisture Extraction Systems: Consider investing in built-in moisture extraction systems in washers, which are designed to reduce the humidity level inside the drum immediately after the wash cycle concludes.

UV Light Sanitizers

Some modern commercial washers come equipped with UV light sanitizers, which use ultraviolet light to kill mold and mildew spores, thus preventing their growth.

Ventilation Improvements

Improving the ventilation in your laundry facility helps reduce the overall humidity and moisture levels in the air, making it less hospitable for mold and mildew.

Dehumidifiers

In very humid environments, using a dehumidifier can help maintain an optimal moisture level in the air, further protecting against mold and mildew.  

Antifungal Treatments

Some commercial laundry products contain antifungal additives that can be periodically added to wash cycles to inhibit the growth of mold and mildew.

For facilities with persistent issues, it may be worth consulting with a hygiene specialist who can recommend custom solutions tailored to your specific environment and equipment.

Air Flow Optimization

• Strategic Fan Placement: Use industrial fans to improve air circulation in the laundry area. Position these fans to push humid air out and pull in dry air, optimizing the overall air quality and reducing moisture.

• Heat Recovery Ventilation (HRV) Systems: Install HRV systems to efficiently exchange indoor air with fresh outdoor air without losing heat, thereby improving indoor air quality and controlling humidity levels effectively.

By applying these detailed and specific tips, your commercial laundry operation may help create a cleaner, safer, and more efficient environment with reduced potential for mold and mildew growth.
