The chemistry is half the process. It wets the tank and the part so cavitation can form at the surface, and it holds the soil once the ultrasound has lifted it.Illustration generated by Misonics.
Why It Wins

Full flushing power, without the foam

Ordinary flushing chemistry foams the moment you pump or sonicate it — and foam is dead energy: it cushions cavitation, airlocks circulation rigs and lies about fluid levels. CoreFlush LF delivers full pH 14 flushing strength with the foam engineered out.

That makes it the version you run in moving systems: ultrasonic tanks, recirculating flush benches, anywhere the solution is agitated rather than still. Oil and residue release from cores and circuits, stay in suspension, and leave with the drain.

Between the two CoreFlush formulations, choose by motion: still soak — standard; anything that pumps, sprays or sonicates — LF, every time.

Applications

Where it earns its keep

Circulating and ultrasonic flushing of cores, coolers and hydraulic circuits.

Why Flash Rust Happens

A freshly cleaned ferrous part is chemically active — protective films gone, surface warm and wet, rinse ions acting as electrolyte. Rust bloom can start within the hour. DI water rinsing slows it; protection stops it.

Protect It

Inhibitor in the final rinse before hot-air drying, an Anti-Rust dip between processes, or a water-displacing film for storage — matched to the next process. Tell us what happens next and the protection specifies itself.

Bath Life

This is not a single-use chemical

A common misconception treats industrial chemistry like dishwater — used once, tipped out. A defended bath of CoreFlush LF works for weeks of production: weir oil separation and filtration defend the bath, solids leave through the filter, and the chemistry keeps working until genuine depletion.

Change out on evidence, not anxiety: when cycle times stretch or results fade at correct concentration, the bath has earned its retirement. Top-ups at specification carry it between changes.

Keep It Honest
  • Skim or weir oils continuously — oil load is bath killer #1
  • Filter solids; drain settled sludge from the sump
  • Verify concentration on schedule per the TDS check method
  • Log it — the trend predicts top-ups before cleaning fades
Storage

Drum and bath, both looked after

The Concentrate
  • Handling: Avoid eye contact and skin contact.
  • Avoid inhalation of vapour, mist or aerosols.
  • Storage: Store in a cool, dry, well-ventilated place and out of direct sunlight.
  • Store away from foodstuffs.
  • Store away from incompatible materials described in Section 10.
  • Store away from sources of heat and/or ignition.
  • Keep container standing upright.
  • Keep containers closed when not in use - check regularly for leaks.

The Working Bath

Lid the tank between shifts — holds temperature, limits evaporation, keeps dust out.

Idle periods: a warm, stagnant aqueous bath can support biological growth over extended stagnation. Circulate periodically, keep concentration at specification, never leave an open tank standing for weeks.

Extended shutdown: drain to sealed, labelled containers — or schedule changeover for restart day.

PPE & exposure controls
  • National occupational exposure limits: TWA STEL NOTICES ppm mg/m3 ppm mg/m3 Potassium hydroxide - 2 Peak - - - limitation As published by Safe Work Australia.
  • TWA - The time-weighted average airborne concentration over an eight-hour working day, for a five-day working week over an entire working life.
  • STEL (Short Term Exposure Limit) - the average airborne concentration over a 15 minute period which should not be exceeded at any time during a normal eight-hour workday.
  • These Exposure Standards are guides to be used in the control of occupational health hazards.
  • All atmospheric contamination should be kept to as low a level as is workable.
  • These exposure standards should not be used as fine dividing lines between safe and dangerous concentrations of chemicals.
  • They are not a measure of relative toxicity.
  • If the directions for use on the product label are followed, exposure of individuals using the product should not exceed the above standard.
  • The standard was created for workers who are routinely, potentially exposed during product manufacture.
  • Biological Limit Values: As per the "National Model Regulations for the Control of Workplace Hazardous Substances (Safe Work Australia)" the ingredients in this material do not have a Biological Limit Allocated.

CoreFlush LF FAQ

Asked at the tank

What dilution and temperature do I run?
Per TDS at 50–70 °C — and the trial sets your exact process values against your soil. Running richer than specified wastes chemical without cleaning faster. That range is the chemistry’s window — not the whole answer. The substrate sets its own ceiling, and it is usually lower: aluminium and anodised finishes discolour above about 65 °C, zinc and coated parts lower again, and magnesium is governed by pH before temperature. Run at the lower of the two. Bath temperature — chemistry vs substrate →
Why do my parts flash rust after cleaning?
Because the clean worked — protective films are gone and the bare metal is active. Rinse DI, then protect: in-rinse inhibitor, Anti-Rust dip, or a displacing film for storage.
When do I change the bath?
When cycle times stretch, results fade, or filtration stops holding the debris. Drain, clean the tank, refill — never lay fresh solution over settled sludge.
Can algae grow in the bath if it sits unused?
Over extended stagnation, any warm diluted aqueous bath can support growth as preservative systems deplete. Prevention: circulate periodically, hold concentration at specification, lid the tank. If a bloom happens: drain, clean the tank including weir and lines with hot fresh solution, rinse and refill — never dose on top of growth.
Can I get the SDS before buying?
Yes — every product ships with its SDS, and documents are available ahead of purchase for your chemical register and risk assessments.
