Non-toxic, biodegradable formulation compliant with OECD 301B and ASTM D5864 standards.
pH-neutral (6.8–7.2) to prevent corrosion on aluminum, stainless steel, and sensitive elastomers.
Zero VOCs (<0.1 g/L), free of halogenated solvents, NMP, and glycol ethers.
Rapid soil removal without residue—ideal for precision cleaning prior to coating or bonding.
Low-foaming profile optimized for ultrasonic, spray-in-air, and immersion cleaning systems.
Electronics manufacturing: flux residue and particulate removal from PCB assemblies and SMT components.
Aerospace MRO: cleaning of turbine blades, fuel system components, and composite tooling surfaces.
Medical device assembly: ISO 13485-compliant cleaning of stainless steel surgical instruments and polymer housings.
Automotive EV battery module production: degreasing of busbars, cell casings, and thermal interface surfaces.
Optics & photonics: particle-free cleaning of lenses, laser optics mounts, and vacuum chamber components.

| Common Compatible Systems | Suitability |
| Ultrasonic cleaning tanks (25–60 kHz) | Highly Recommended – Stable performance at 40–55°C; no cavitation inhibition |
| Batch spray-in-air washers (stainless steel construction) | Highly Recommended – Low foam ensures consistent nozzle flow and uniform coverage |
| Recirculating immersion systems with filtration | Recommended – Compatible with 5–20 µm bag/cartridge filters; minimal sludge formation |
| Robotic spray stations (electrostatic or air-assisted) | Suitable – Viscosity (1.8–2.2 cP) enables fine mist generation; non-conductive after drying |
Q1: What is the CAS Registry Number for CLEANER 7#?
A: CLEANER 7# is a proprietary multi-component formulation; individual ingredients are listed under their respective CAS numbers in the full Safety Data Sheet (SDS Section 3). The product itself does not carry a single CAS number per IUPAC guidelines for mixtures.
Q2: What is the recommended working concentration and temperature range?
A: Dilute 5–10% v/v in deionized water. Optimal cleaning occurs at 40–55°C; effective down to ambient temperature for light soils with extended dwell time (3–5 min).
Q3: How does CLEANER 7# compare to solvent-based cleaners like nPB or TCE in terms of residue and extractables?
A: Unlike chlorinated or hydrocarbon solvents, CLEANER 7# leaves no volatile or semi-volatile extractables. Residue testing per USP <87>/<88> and ISO 10993-12 shows <0.5 µg/cm² non-volatile residue—well below thresholds for medical and aerospace applications.
Q4: Is CLEANER 7# certified for use in food-contact equipment cleaning?
A: Yes—it holds USDA A1 Nonfood Compound registration and complies with FDA 21 CFR 173.370 for indirect food contact surfaces when rinsed with potable water per validated procedures.
