Cleanroom Disinfectants

Validated microbial control for critical environments

Disinfectants are a core part of every cleanroom contamination-control program. While cleaners remove soils and residues, cleanroom disinfectants are designed to reduce microbial load on surfaces in a way that supports validated SOPs and regulatory expectations. SOSCleanroom has supplied critical environments since 1981, and we stock disinfectant chemistries that are trusted in pharmaceutical, biotech, medical device, semiconductor, compounding, and laboratory cleanrooms where sterility and yield depend on consistent surface control.

This category includes the primary disinfectant types used in controlled environments — from filtered 70% IPA and ethanol blends for rapid daily wipe-downs, to quat-based and hydrogen peroxide disinfectants for broad-spectrum control, and sporicidal solutions for periodic kill of resistant organisms. Many facilities also follow validated disinfectant rotation programs and specified dwell/contact times to maintain efficacy over time and meet audit requirements. As always, verify material compatibility and follow the product’s technical data and your SOP for dilution, application method, contact time, and rinse requirements.

Browse SOSCleanroom disinfectants below to match the right chemistry and format to your cleanroom class, organism risk profile, and compliance standard — and lean on our expertise when the disinfection step is critical to your environment.

Disinfectants FAQ

  • Q. What types of cleanroom disinfectants are available?

    +

    A. There are several types of cleanroom disinfectants, each with unique properties and applications:

    • NaDCC Chlorine Tablets: These are bleach substitutes that can be dissolved in water to create a disinfectant cleaner for hard surfaces.
    • Phenol/Phenolic Disinfectants: These contain phenol compounds and are effective against bacteria, viruses, and fungi.
    • Quaternary Ammonium (Quat): These are EPA-registered one-step cleaners and disinfectants, like Conflikt 4104, that are fragrance and dye-free.
    • Sporicides: These are powerful disinfectants effective against spores, such as Clostridium difficile (C. diff).

  • Q. How do I apply cleanroom disinfectants?

    +

    Cleanroom disinfectants can be applied using various methods, including:

  • Q. Can I use cleanroom disinfectants on any surface?

    +

    A. While cleanroom disinfectants are versatile, it's crucial to read the manufacturer's guidelines for specific surface compatibility. Some disinfectants may not be suitable for certain materials or finishes.

  • Q. What are the storage requirements for cleanroom disinfectants?

    +

    A. Cleanroom disinfectants should be stored in a cool, dry place, away from direct sunlight and heat sources. Always keep them in their original containers to prevent contamination and ensure efficacy.

  • Q. Can cleanroom disinfectants be used with wipers?

    +

    A. Yes, cleanroom disinfectants can be used in conjunction with cleanroom wipers for effective cleaning and sterilization. However, many cleanroom wipers contain isopropyl alcohol, so you must read the manufacturer’s instructions to ensure IPA won’t interact negatively with your cleanroom disinfectant.
