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

Get the oil out of places you cannot see

When an engine lets go, the debris and oil go everywhere the oil went — through the cooler cores, the galleries, the passages no brush reaches. Reassemble around residue and the new build inherits the old failure.

CoreFlush is purpose-built flushing chemistry: it releases oil films and residues from internal circuits, carrying them out in suspension so the rinse actually finishes the job. Run it through coolers and blocks after solvent cleaning or machining, and what drains out is the argument for having used it.

For circulating rigs and ultrasonic tanks where foam would kill the process, its low-foam sibling CoreFlush LF does the same work quietly at pH 14 strength.

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 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 repeated or prolonged 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.

CoreFlush 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.
