CiDecon II is used when teams need a single concentrate that can both remove soil and deliver broad-spectrum disinfection on washable, non-porous surfaces. A common scenario is a busy lab or production support area where benches, carts, stainless panels, and equipment exteriors pick up fingerprints, splashes, and “invisible” residue throughout the day. The operational goal is simple: clean thoroughly, keep surfaces wet long enough to meet the label contact time, and avoid process drift caused by inconsistent mixing or short dwell times.

• Routine disinfection of washable, inanimate, non-porous surfaces in labs, production areas, and on process equipment.
• Situations where both cleaning (soil removal) and disinfection are required without adding extra steps.
• Programs that want verified performance in the presence of organic soil load and hard water conditions at the use dilution.

• Concentrated phenolic detergent-disinfectant designed to clean, disinfect, and deodorize in one step.
• Defined preparation method: 1 ounce per 1 gallon of water (1:128) and a 10-minute wet contact time.
• Efficacy claims supported by A.O.A.C. protocol testing at the use dilution in the presence of 5% blood serum and 400 ppm hard water as CaCO3.
• 2-year shelf life stated for the concentrate; fresh solution is recommended for each use.
• Hazmat controls are explicit (ground shipping only), which helps facilities plan receiving, storage, and internal distribution.
• Decon Labs is a recognized supplier in laboratories, cleanrooms, and process areas; SOSCleanroom has been a distributor of Decon for over 10 years supporting cleanrooms across the United States.

CiDecon II is a liquid, concentrated phenolic detergent disinfectant. The Technical Data Sheet lists the following active ingredients in the concentrate: ortho-Benzyl-para-chlorophenol (13.2%) and ortho-Phenylphenol (24.8%), with inert ingredients (62.0%). The Safety Data Sheet identifies transport classification information for a corrosive disinfectant liquid and notes potassium hydroxide in the shipping description; concentration of potassium hydroxide is not stated in the excerpts provided on the SDS.

The Technical Data Sheet positions CiDecon II for broad-spectrum disinfection and notes confirmation testing at the use dilution (1:128) in the presence of 5% blood serum and 400 ppm hard water as CaCO3 with a 10-minute contact time. Practically, that matters because “real” surfaces often have a combination of residues (skin oils, process dust, splashes) and water quality can vary by facility.

• Residue control: Phenolic disinfectants and detergent systems can leave films if over-applied or if rinse/wipe steps are skipped. The label direction includes rinse with water, wipe, or air dry; facilities with tight residue limits typically define a follow-on wipe/rinse method inside their quality system.
• Compatibility and safety: The SDS classifies the product as corrosive and provides transport information consistent with corrosive disinfectant liquids. Before broad rollout, confirm compatibility with painted surfaces, plastics, elastomers, and coatings used on your equipment.
• Process control: The most common performance issue is not chemistry—it is execution (wrong dilution, poor wetting, or early wipe-off). Treat measuring and dwell time as critical control points.

• Packaging: 1-gallon bottles, 4 per case.
• Sterility: Not stated in the SOSCleanroom product page or Decon Labs product page/tech sheet.
• Traceability: Decon Labs provides a Certificate of Analysis lookup on the product page (lot-based); availability of lot documentation should be confirmed at receiving based on your internal requirements.
• Country of origin: Not stated in the SOSCleanroom product page or Decon Labs product page/tech sheet.
• Shipping controls: SOSCleanroom flags the product as hazmat, requiring ground shipping only, commercial address only, and a $35 hazmat fee per case.

The Tech Sheet includes label-direction language. The workflow below mirrors those requirements and adds practical execution controls that help prevent “quiet failures” (short dwell times, wrong dilution, missed surfaces).

1. Pre-clean gross soil: Remove heavy soil or gross filth first. If soil remains, the disinfectant cannot reliably contact the surface.
2. Mix precisely: Add 1 ounce of concentrate per 1 gallon of water (1:128). Use a dedicated, labeled measuring device. Do not “free pour.”
3. Do not mix chemistries: The label states “DO NOT MIX WITH OTHER CLEANERS.” Treat this as a hard rule—mixing can reduce efficacy and create unsafe reactions.
4. Apply to wet thoroughly: Use a cloth, sponge, mop, or mechanical sprayer to wet the surface thoroughly. Avoid creating fine mist where inhalation risk increases.
5. Hold the surface wet for 10 minutes: Start timing only after full wet-out. Re-wet if edges dry early (common on vertical stainless and warm equipment skins).
6. Finish per label: After the 10-minute contact time, rinse with water, wipe, or let air dry—based on your surface type and residue limits.
7. Use fresh working solution: The Tech Sheet recommends preparing a fresh solution for each use. From a QA standpoint, this reduces variability and supports repeatable execution.

• Short dwell time: Wiping dry at 2–3 minutes instead of maintaining 10 minutes wet contact.
• Wrong dilution: “A splash in a bucket” leads to under-dosing or over-dosing; both create risk (efficacy loss or residue/compatibility issues).
• Mixing with other cleaners: Violates label direction and can undermine performance or create safety hazards.
• Skipping gross soil removal: Disinfectants do not compensate for heavy, layered soils.
• Material incompatibility surprises: Not testing on coatings/plastics first, then discovering haze, swelling, or discoloration after rollout.
• Residue drift: Over-application without a defined rinse/wipe strategy in areas with tight film/residue limits.

Facilities typically evaluate phenolic concentrates against other validated hard-surface disinfectant chemistries based on organism claims, residue profile, compatibility, and execution practicality. Examples commonly used in critical environments include:

• STERIS Vesphene® III se Phenolic Disinfectant: Phenolic disinfectant concentrate positioned for routine disinfection of hard, non-porous surfaces in pharmaceutical/cleanroom environments.
• Ecolab Oasis Pro™ Surface Disinfectant Cleaner (phenolic): A phenolic-scented disinfectant-cleaner concentrate format used in institutional programs (verify site-specific label/claims and residue expectations).
• STERIS Coverage Plus NPD® Cleaner Disinfectant (quat concentrate): A one-step concentrate built on quaternary ammonium chemistry; often compared during rotation-program design when facilities weigh phenolic vs. quat performance tradeoffs.

CiDecon II is a strong fit for controlled-support spaces where hard, non-porous surfaces require routine disinfection with defined execution parameters (dilution + dwell time) and where teams want a detergent-enhanced phenolic that can clean and disinfect in one step. Because it is shipped as hazmat with ground-only requirements, it also fits facilities that have established chemical receiving controls, segregated storage, and trained handling practices. If you operate under strict residue, compatibility, or documentation constraints, treat dilution control, dwell-time verification, and post-application finishing steps as program-critical controls.
