In many cleanrooms, the “hardest-to-remove” soils are not particles — they are films: tacky mat residue tracked into corridors, adhesive ghosts on carts, photoresist stains around wet benches, flux residues near rework benches, and greasy fingerprints that keep reappearing on stainless and painted equipment. MegaClean is positioned as a heavy-duty detergent/degreaser that targets those problem soils while avoiding the operational risks of solvent flammability.

SOSCleanroom (SOS) has been a proud distributor of Micronova for over 15 years supporting critical environments. When facilities standardize a heavy-duty cleaner, they typically want repeatable results, predictable documentation, and lot traceability that holds up during QA investigations and internal audits.

• Degreasing and heavy soil removal on cleanroom-compatible hard surfaces where solvent-based cleaners are undesirable.
• Adhesive residue removal (including tacky mat residues) on carts, wheels, thresholds, and staging fixtures.
• Photoresist stain cleanup and spot cleaning in semiconductor and electronics workflows.
• Parts cleaning and immersion/soak cleaning (where your SOP allows) followed by a defined rinse step.
• Floor and high-traffic-area cleaning when film build-up and scuff/track marks are not responding to routine neutral cleaners.

• Heavy-duty degreasing performance positioned as an alternative to flammable solvent cleaners such as acetone and isopropyl alcohol.
• Non-flammable, biodegradable, and water-soluble profile for facilities managing EHS risk while still needing strong cleaning action.
• Documented packaging configurations and traceability controls (case and individual container lot marking).
• Designed for cleanrooms and controlled environments; manufacturer documentation references ISO 5 through ISO 9 use ranges.
• Container flexibility for different workflows: 1-gallon for point-of-use refills and 5-gallon for higher-consumption cleaning programs.

Manufacturer product specification literature describes MegaClean as a heavy-duty detergent and degreaser manufactured at Micronova’s Torrance, California facility and produced within an ISO 9001-certified manufacturing environment. The product is water-soluble and positioned as non-flammable and biodegradable for controlled-environment cleaning.

Safety Data Sheet information identifies MegaClean as a mixture containing 2-(2-butoxyethoxy)ethanol and a (C9-C11) alkyl alcohol ethoxylate, with a primary labeled hazard of serious eye irritation. In practical terms: treat this as a powerful detergent system and build PPE and rinse discipline into your cleaning method.

MegaClean is positioned for heavy soils: grease, adhesives, and photoresist stains. The key to getting “clean” instead of “spread thinner” is to treat this as a two-part operation: remove the soil with controlled dwell/contact time, then remove the cleaner itself with a defined rinse (and, where your SOP requires it, a final wipe-down for visual cleanliness).

• Dwell matters: manufacturer brochure guidance suggests 3 to 5 minutes dwell or immersion time for heavy-duty cleaning use cases.
• Concentration discipline: brochure guidance suggests 50% or greater concentration for heavy-duty cleaning and 10% to 25% for medium-to-heavy cleanup, followed by rinse.
• Rinse is not optional in most critical uses: manufacturer brochure guidance indicates a production-quality water or IPA rinse is typically required after use.
• Safety and handling: SDS indicates serious eye irritation hazard; build eye protection and controlled dispensing into your method, especially when spraying or pouring.

• SOS purchasing options: 1 gallon (4 per case) and 5 gallon (1 per case).
• Manufacturer packaging (product specification): MC1-G: 4 bottles per poly-lined case; MC1-5G: 1 pail per poly-lined case; MC1-Q: 8 bottles per poly-lined case.
• Traceability: lot numbers printed on each case and on each individual container; COA support available with orders and/or upon request.
• Sterility: not stated in the SOS listing or manufacturer product specification.
• Country of origin: manufactured at Micronova’s Torrance, CA facility.

Heavy-duty cleaners fail in cleanrooms for one predictable reason: the soil is lifted, then redeposited because the wipe/mop path and rinse step are not controlled. Treat MegaClean as a defined cleaning event with a start, a soil removal endpoint, and a verified rinse endpoint.

• Residual film after cleaning: usually caused by skipping or under-performing the rinse step, or reusing a loaded wipe/mop face.
• “Clean today, haze tomorrow”: classic sign of partial soil removal and re-deposition; tighten wipe-face changes, dwell discipline, and rinse endpoint.
• Cross-contamination: using the same mop bucket or wipes from floors to benches without segregation controls.
• Safety drift: eye protection skipped during dispensing; SDS indicates serious eye irritation hazard — treat decanting/spraying as higher-risk moments.
• Unknown concentration: “a splash in a bucket” leads to variable outcomes; set defined dilution ranges per your SOP and train to them.

When comparing heavy-duty cleanroom detergents/degreasers, focus on: filtration, residue/rinse behavior, compatibility with your tools (mops, wipes, ultrasonic baths), documentation support, and whether your SOP can reliably remove both the soil and the cleaner itself.

• Contec heavy-duty cleanroom detergent systems (verify filtration and residue/rinse requirements against your acceptance criteria).
• STERIS/Klercide cleaning products intended for controlled environments (verify intended use and documentation support).
• Ecolab cleanroom-appropriate cleaners for heavy soils (verify residue profile, rinse requirements, and surface compatibility).

Manufacturer literature positions MegaClean for controlled environments and references use across ISO 5 through ISO 9 cleanrooms. In practice, it is best suited for: (1) scheduled “film removal” events where routine neutral cleaners are not enough, and (2) documented changeover cleaning where residues and adhesives can compromise product quality or downstream inspection.

• Semiconductor/electronics: photoresist and flux-related cleaning scenarios where flammable solvent risk is a concern and rinsing is tightly controlled.
• Aerospace/precision build: degreasing for fixtures, carts, and parts cleaning where you need repeatable outcomes and strong documentation.
• General controlled manufacturing: floors, high-traffic thresholds, and equipment touch points where adhesive films and greasy soils accumulate over time.
